KEYESTUDIO Raspberry Pi 4WD AI Robot Car Starter Kit with Camera Video Python Programming for Adults (Pi NOT Include), Face Tracking, QR Code/Color/Gesture Recognition, Matrix Expression, IR Remote

This is a quality product which is very study and well made. The assembly instructions are clear and easy to follow. All the screws and fittings are in separate bags which makes it easier to identify them. The fact that the pan and tilt kit for holding the camera comes completely assembled with the servos already in place is a great bonus.The basic functions of the robot including line follower, ultrasonic follow and avoidance and InfraRed remote control are easy to code and provided with clear explanations of how the code works. The Camera adds a number of extra features including face , colour and QR code recognition.The Mobile phone App allows you to dive the robot independently and view on your phone what the camera sees (which can also be adjusted). You can also use the computer and remote control to drive the robot.The documentation also includes a PDF Python Programming Book. This is an excellent education tool for developing coding skills and how the use of AI can be incorporated into robotics.

The cost for all the parts were reasonable. Assembly was ok. Ultrasonic and LED screen connections were swapped. When trying to run the motors the power supply droops removing power from th Raspberry Pi.The servos worked well and are fast. The supplied code needed changing to make them work.I would not buy unless you are. just buying for the parts.I would hope that the supplier.replaces the control board. If so I will add to my review.So the issues were as follows:1) The lead for the Ultrasonic detector and Led panel were the wrong way round in the instructions, swapping them rectified that issue2} There are two python programs that run on startup, these affect the motor driving going through the tutorials. I disabled them and now it works better3) I added a capacitor to the ROI power input and tgat stopped resets

I bought this kit and found that even though the instructions were not brilliant, I was able to build the car.However, as mentioned in two recent reviews, the software code instructions are rubbish. It was only through another review did I find out that the connections within the instructions for the LED display and the Ultrasonic connectors are reversed on the drive shield. Another complains of poor coding, which I agree with as I found source code on the internet that makes the servor motors work more smoothly than the code provided.I also found that the VNC instructions were rubbish and did not work and took some fiddling with.I had trouble with the 4wD Motor Drive Shield which has a Keyestudio code of KS3019 was not referenced on Keyestudio's websites and so troubleshooting the issues I had was not easy. I had same issue with the length of the camera ribbon cable being too short causing issues when the camera is rotated/tilted as well.So the overall view for me, given that I have emailed Keyestudios for advice and had no response is, avoid this product as there are far better kits out there with far better customer support.

The kit isn't terrible for the price, but there were/are a number of issues. It's all well packaged but let down by poor documentation and some iffy quality control.First hurdle was right at the beginning of the build where the screw holes didn't align with the aluminium posts. This meant I had to drill the screw holes out wider to enable post attachment. Not a massive deal and once that was done everything else seemed to go together securely - although don't make the mistake we did and leave the film on the acrylic panels before assembly! It's not obvious it's supposed to be removed and wasn't mentioned in the instructions to remove it first.Once everything was built I discovered the VNC setup didn't work as suggested in the instructions. It required allsorts of fiddling with settings and finger-crossing before I could get it to work. That's done now too and I finally managed to get the robot responding to some of the test scripts. However it's not all rosy. The LED metrix refuses to respond to anything at all. I'm unsure if that's hardware or software related though and unsure how to test. Everything is connected securely and as directed.Anyway, TL:DR - avoid unless you're a) pretty technically proficient with both tools and programming, and b) willing to work around less than ideal instructions on technical installations and put in extra time to troubleshoot or figure out alternative solutions.This is not something you can buy for your brainy kid and leave it to them to tinker with.With a little more work and accessible and responsive customer support channels I'm sure this could be a fantastically successful product, but I'm not sure I can recommend it as is.

As expected
