KEYESTUDIO Self-Balancing Robot Car Kit for Arduino DIY Project, Wireless Bluetooth Control, Strong DC Motors, Robotics and Electronics STEM Smart Car Kit for Adults to Build

The Keyestudio products are some of the better Arduino robotics products. They provide online instructions in passable English. They also provide good examples code you can copy. This is the second product from Keyestudio I have assembled. I have purchased other Arduino products from other companies, that look good until you discover that there are no accurate instructions, and in some cases absolutely no code. The balance car is more fun than a barrel of monkeys, and easy to assemble.

This product is a great idea. Mechanically, it works great! However, the smart phone app that is a part of this is almost useless. You can control the robots direction of movement with the app. However, the reason I purchased it, to be able to make adjustments to the PID balancing of the robot on the app, does not work at all. There is zero technical support (to my knowledge) so you are completely on your own. I am not a new comer to this type of product. I can usually figure these things our by Googling, YouTube, etc. Not with this guy. There is nothing that I have found to help me make this work like it should. This could be a 5 star product but with very little tech support via documentation / videos, etc, at best I can only give it 2 stars. If anyone out there knows where to find more info, please share with me.

Was a breeze to assemble and fun, too. Had a blast with programming and tweaking the bot. Would recommend.

Ran into nothing but problems with the programming. I got this for a project for my son and I to do. I spent over 6 hrs trying to find out why 1 of the programming coding wouldn't work. the Keyestudio website was no help. the instruction where no help and no technical sup. After finding how to fix for the problem on You-tube, i download this app. let me tell you, this app if could give negative stars i would. it looks like something someone made in 5 min. Oh and by the way IT DOESN'T WORK. Every time you link the Bluetooth is gives you a error 15 and a bunch of Chinese lettering. and like i said no tech support.i will never buy another Keyestudio product again

Note: I’m a repeat buyer from Keyes Studio store, and I received discount offer for this kit - it’s normally 80, but I paid $12 with their test and evaluate code.This is a very well designed and high quality kit with very good build and coding instructions. You'll want to follow along with the product's wiki which you can find by searching for "KS0193 keyestudio wiki." Build is very straightforward for any young semi-experienced builder - the directions are clear and parts are well labeled. The wiki runs you through a dozen projects to make sure all parts of the kit work (shield buzzer, motor controller, accelerometer/gyro, bluetooth), then it introduces you to feedback loops and filters for the balancing program. You can run through these in a couple hours, just go to the last (best) one and load it, or go down internet rabbit holes and learn about Kalman filters, positive feedback, and PID control.Either way, at the end, you will end up with a sturdy 2 wheel robot car that balances really well and that you can control via a bluetooth app.

The assembly instructions are very clear, simple and easy to follow, the tools provided with the package are of very good quality and are exact to assemble the components.The materials of the components are top quality, the separation and labeling of the screws helps a lot.Its aesthetic appearance is very sober and elegant.The instructions to access the source codes and libraries are very simple.At the time of evaluating the operation, I did not find any fault, it was connected without problems via Bluetooth with my Android device, it works from the first moment, only detect that at the time of being in standby mode, if it leans a little forward or backwards, the robot accelerates in that direction until it falls, but is easily corrected from the remote control, which responds perfectly.Perform tests on horizontal plane and inclined plane, from 5 to 45 degrees, always remained standing, I also tested it by placing loads of different sizes and shapes on top of the robot, it remained standing all the time.
