Project Upgraded Tracking Ultrasonic Bluetooth (Elegoo) 4715

Review for uno project upgraded smart robot

Price was $72.42. I bought this kit (the upgraded version 2) to play with my 11 y/o grandson who also got the kit for christmas. It was about a 2 hour build and the version 2 wiring harnesses simplified the kit building. More fun was getting into the c programs that run the car! we adjusted the speed downwards for some of the forward/back motions to save wear and tear on hitting obstacles. Also found errors in the line tracking program making it not work properly. I will post to elegoo my version of the corrected program. When corrected, it runs great. The big problem was the sensors send a high signal when over black and the light of the sensor goes off and a low signal when over light colored surface and light of the sensor is on. Don't know why elegoo didn; t find this out if they tested it. All in all it is a great robot car to play with and experiment with c programming on the "lessons" provided.

Uno Project Upgraded Smart Robot Car Kit With Uno R3, Line Tracking Module, Ultrasonic Sensor, Bluetooth Module Ect Review (el kit 010)

Some of the translation was off a bit but i guess that is to be expected. For the price you can't beat this as great starter into robotics and arduino. My ten year old and i plan on attaching a robot arm with another arduino to perform some basic tasks the platform for this smart robot car kit is bigger than i thought. About nine inches long, and seems pretty sturdy. The build quality seems ok to good. I work with alot of elctronics and these arent the best i have seen but again for the price very nice. One of my motors had the polarity reversed. My son actually caught it before me and sense they soldered plugs onto the motor to fit into the motor driver board we just resoldered the motor. Just pay attention to all of the components. I was fortuante enough to be able to resolve the problem so i do not know what the return process would have been like. Also the instructions are not always clear cut. You need to make sure you add the proper libraries to the arduino sketch. Some of the other elegoo projects i have done already had all of the libraries added for you. One last thing, the ir sensor is not very responsive, you have to press the button a few times to get the car to follow the command unless you are right at the senser. I am going to try and modify so that the sensor is pointing up, or just try the bluetooth version. Either way that is the reason why not 5 stars(some quality issues and not clear cut instructions for beginners. ). . Don't pay attention to one star review anybody with any computer experience could have fixed that problem. Pproblem is that they were mac user. Macintosh is purposely made so that you can't manipulate things, it's defeats the purpose of programming your own robot mcintosh doesn't want you programming anything. It is kind of ironic. Made by some of the most brilliant programmers but they stand in your way when you try to think outside the box. Last paragraph is just my two cents and not related to this product at all. -X.

Uno Project Upgraded Smart Robot Car Kit Uno R3, Line Tracking Module, Ultrasonic Sensor, Bluetooth Module Ect
Click to see NoticeProject Upgraded Tracking Ultrasonic Bluetooth (Elegoo)"I wanted an introduction to the arduino universe, and this kit is a great way to start. For reference, arduino boards are autonomous microprocessors with extensive i/o connections that you can program in a c variant from your computer. The kit includes an arduino uno board and some sophisticated i/o options that would take you considerable time and effort to collect. The primary output is to a motor controller with individual speed and direction control on each side. Input options include infrared communications with a controller, a rotating ultrasound proximity sensor and an array of line sensors. My ultimate goal is to program it to find its way through a maze. . Some precautions. This is not a toy that you will assemble in one night to amuse the kids. It is an extended learning experience that takes some experimentation. The manual is written by a non-native english speaker, and several sections involve some head scratching. Nonetheless, the kit was developed with such sincerity that you have to forgive small flaws. All the parts are of high quality, everything is meticulously labeled and the rechargeable batteries have enough capacity to send the car to alaska."

The F.A.Q. for uno project upgraded smart robot car kit with uno r3, line tracking module, ultrasonic sensor, bluetooth module ect

The robot v2 kit from elegoo was a fantastic purchase for my family. I have 7 year old kids who are fascinated by robotics but are not quite ready to understand the intricacies that go into building a robot from scratch. This kit took away all the guesswork - literally everything you need down to the screwdrivers was in this kit. I had no idea what to expect and was honestly hoping it was going to be a multi day project, but we were done with the physical build in maybe 3h - this was with me trying to get the kids to do as much of the fiddly nut and bolt attachment as possible. . The instructions were laid out in folders - step 0 was the physical build. The other documents contain the instructions as well as the arduino sketches to run the car in that mode. I. E. Ir mode vs bluetooth mode vs object avoidance. These documents are also well thought out - for example the bluetooth mode has 2 sketches, one for turning a light on and off and the other is the full car control mode. This lets you debug the bluetooth connectivity without the car launching off the kitchen table (more on that later). . The kit itself comes in a perfect project box with every component and screw bag clearly labelled to make it easy to identify. The pieces are high quality although clearly selected to be budget conscious. The result was an amazing value in my opinion. The finished car is pretty resilient - at one point one of the kids used bluetooth mode to drive the car off the kitchen table from another room. This bent the bluetooth module and the board connector. Using the included mini screwdriver i was quickly able to bend things back into place and we were up and running again. The main frame is nice and sturdy without any sharp edges to hurt little hands. . If i was going to make any minor suggestions for v3 of this kit, i might focus on the documentation for the bluetooth mode. My module identified differently from the documentation and i later realized that the old iphone i was using must have had iffy bluetooth connectivity. A quick google and a different bluetooth phone later and i was up and running, but it was a bit non-intuitive. It was also not clear in the instructions that the brown sticky paper covering the black acrylic frame is removable - we realized half way through and had to demount stuff to remove the paper. The final tiny point is that the bluetooth module is super exposed - it sticks vertically from the top of the car and is prone to snag when driving under things or if the car rolls. With a slight change to the board design it would probably be easy to mount that somewhere safer given that it is one of the few delicate components. . Anyway, full stars and 10/10. We loved this project and look forward to playing with all the modes soon. My challenge for the kids is to combine the object avoidance with the bluetooth mode so they cant crash into stuff - that is outside the elegoo documentation and should make them think a bit. Thanks for a wonderful kit and a wonderful project! as an open challenge to elegoo - make a robot arm with similar quality/bluetooth etc - i would buy it in a heartbeat!

A number of questions have been asked here.

C. Wade, Haute-Normandie says

My daughter assembled this in a few hours with only minimal help from me, mainly to identify some components. The assembly "instructions" are somewhat disappointingly just a series of photos (think ikea), but they were clear enough that she was able to puzzle it out. Everything fit together well except for one small metal standoff that seems not to be threaded all the way through, but that was no big deal. Getting the car to actually do something is slightly more challenging than physically assembling it, but not if you are somewhat familiar with installing software. My daughter was thrilled when she uploaded the first example program to the car, turned it on and it started roaming around on its own. My only criticism is that the programming docs could use some editing due to language barrier.

D. Matherly, Windsor and Maidenhead

This kit would be a good value except for a problem that i'll describe below. The instructions are adequate, parts are mostly good quality and the boards are clearly labeled. Assembly is easy. The arduino code provided with the kit is useful and informative. The design of this kit is well thought out. . However, after assembling the kit, i noticed that the car would not move in a straight line. One of the wheels was rotating slower than the other three, causing the car to turn and making movement in a straight line impossible. I examined the 4 dc motors that were provided in the kit and discovered that one of the motors was geared lower than the other three. See the photo below. . I reported the problem to elegoo. Elegoo hasn't responded to my problem report or done anything to rectify the problem. Elegoo won't even provide specifications for the dc motors so that i can purchase replacement parts myself. A total lack of support. I should also note that documentation of some individual modules is in chinese (i. E. The l298n motor controller) and documentation providing specifications for the dc motors included in the kit is entirely missing. . Update:. . Once i finally made contact with the elegoo support team their response was terrific. They didn't just replace the defective motor, they shipped an entire kit! problem solved. Thank you elegoo, both the kit and your support are terrific.

Q. Lynette, Missouri says

 i gave it five stars because it is a great project for the price. The car can be built in a weekend and requires no soldering. I am an experienced computer engineer and maker, so, the kit was easy for me and i was able to troubleshoot problems quickly. Anyone that is handy with a screwdriver will be able to assemble the kit and get the car working. There is a good instruction manual and all the software is provided on a disk by elegoo. However, if you have a child in middle or elementary school, this is not a kit that they can assemble by themselves; adult supervision and coaching is required. I suggest you buy a kit and assemble it yourself first, then teach your child how to do it. If you run into problems, there are videos on popular video streaming sites that describe the construction and software. . I ran into a few problems which elegoo is very good about correcting. I haven't ordered the kit recently, but, i'm guessing that they have fixed a lot of the problems that i ran into. They are very responsive and helpful. . Because the kit is inexpensive and engineered to exact specifications, adding features such as cameras or audio would be challenging with the arduino uno. The uno is almost fully utilized, there is only one spare gpio pin. However, you can free up pins by reducing other capability, for instance, disconnecting the line following sensors. In addition, the wheel encoders are not implemented, therefore, the software does not know when the wheels are not turning and it cannot measure distance or speed. . The car has limitations, but they are acceptable for the price. I think its a great weekend project and a lot of fun for kids.

G. Cathy, Peterborough

Not sure what is in the v2 upgrade of this as i received the v1 version just a couple of weeks ago. Some of the issues i had may have been fixed in the new release. . First, the good: nicely packaged, very good selection of components, nicely constructed chassis and good layout for mounting the motors and boards etc. Went together easily, with very little ambiguity in the design. . The not-so-good: following the construction instructions results in a non-workable result. The layout and wiring for the motors described in the documentation results in a robot with wheels on the same side that rotate in opposite directions! fix this easily by either mounting all 4 motors in the same orientation, or switch the wiring on one motor on each side. The programs supplied with the kit are rather poorly written. They serve as a good basis, i suppose, but having to rewrite them to even get basic functionality is a little disappointing - at least one sketch defined the wrong pin for one of the motor drive outputs, resulting in a poor robot spinning in circles until i fixed that. . If you know what you are doing, or have no expectations of this working perfectly "out of the box", then this is a good purchase. Not only is it a good jump-start into the world of arduino robotics (including the l298n h-bridge module, a servo, bluetooth and ir-control - all staples of entry-level robotics). Longer-term, all the components are generic enough to be reused in a range of projects. On the other hand, if you have no experience with arduino programming or robotics/electronics, i would not recommend this as a good entry point.

Quick and fun build. Needed a replacement part and they responded promptly. Great product and customer service!

L. Smith, Rotherham

Product as expected - thanks!

Y. Patricia, Devon says

Worked well except the blue-tooth radio on the car. I think 2 of the pins are wired backwards. When that happens, the car won't receive programming.

I like it

So i received this kit a little more than a week ago, and was so excited that i brought it to work with me and completed it during an 8 hour shift. It is very easy to set up if you follow the included instructions (may even be intuitive to some). The instructions are clear and to the point - i used the . Pdf available online, as i hardly ever touch cds these days. All of the parts listed come with the set, along with the tools needed for the project as well, although i feel like a tiny socket wrench would have helped with the tinier nut/screw tightening. The only true complaint that i (had) with this kit is that the screws included to fit the ir receiver don't truly come together for a tight fit on the base - it leaves a very small gap, so the ir receiver will wiggle just a bit no matter how much you tighten it (but if you have extra shorter screws this can be remedied easily). The ir receiver is still fully functional though otherwise. . The projects included with the kit are pretty easy to understand and implement. Of course they can be modified to fit your needs, and there are all other sorts of sketches available on the internet to make your robot do different things. For instance, currently i'm working on a program to make the robot run away from me by using a motion detection sensor. I have uploaded and tested all of the included sketches, and they work pretty perfectly on the first try. I really like the line following capability, and the bluetooth control is pretty amazing - being able to control your robot's every move from your phone is awesome. The ir control is okay, works like it is supposed to, but i'm not a huge fan of the included remote control, but that doesn't sway me from a five-star review of this product. . You may also do well to check out some sensors to do your own add-ons for this kit - i also would suggest a backup set of batteries if you plan on getting a lot of use out of this thing. The batteries are 3. 7 li-ion rechargeable (a bit bigger than aa). . This kit will keep you busy for awhile if you are an open-minded individual. With that said, this is great for kids as well as adults. Pick one up and you won't be sorry! . . The links for the motion-detection sensor and other mentioned optional items are below:. .

This is a great robot kit for learning how to build and program robots. - good assembly instruction available from the elegoo website. - components fit together nicely. - the plastic base and top are made of sturdier construction that similar kits i have purchased. - excellent customer support. I had a couple of questions and elegoo answered each of them within a couple of business days, including sending me some upgraded arduino sketches, an updated android application, and an updated arduino library. - the furnished sketches do not provide for speed control but the kit attaches the speed control capability to pwm pins so it was fairly easy to change, for example, change. Digitalwrite(ena, high); . To. Analogwrite(ena, abs); . In the functions, . Then add functions for speeding the car up and slowing the car down, for example:. // move car faster. Void mup(). . If (abs 255) // make the car go faster. . Abs abs + 10; . Analogwrite(ena, abs); // analog output allows pwm speed control. Analogwrite(enb, abs); // analog output allows pwm speed control. Serial. Print("faster "); . Serial. Println(abs); . . Else. . Serial. Print("fast enough! "); . Serial. Println(abs); . . . . Then in the void loop() add calls to the new functions, for example, . Else if(getstr 'u') // speed up. . Mup(); . Delay(200); .

This is an amazing value, perhaps the best robot car kit on the market. Very professionally packaged and easy to put together (version 2. 0, the 2016 version, is much improved in this respect due to a revised arduino shield that has easier to use connectors that cannot be plugged in incorrectly). It's quite easy to add a raspberry pi and camera to this and make it an advanced computer vision autonomous car for less than $135!

These are excellent and affordable products. Great fitting for the class robotic projects i needed them for. I am happy with my purchase.
