Best project upgraded tracking ultrasonic bluetooth (elegoo) in review

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:. .

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.

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

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 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.

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.

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.

Product as expected - thanks!

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!

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.

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); .

Great product no issues with so far. Still working on more programming projects. Fast shipping, it had arrived before expected time. I would recommend this product.
