MasterPi 5DOF Robotic Arm for RaspberryPi 5 AI Vision Tracking Target Sorting Line Follow Open Source Programming Smart Robot Car Kit for Teen Adult STEM Educational Building Robot, with RPi 4B 8GB

I loved how the customer service from HiWonder gave really fast responses on questions about their product. The robot allowed my son and his friends to experiment with robotics, implement object detection algorithms and more without having to worry too much about making sure the hardware was correct. Regarding the product, we recommend it for anyone who wants to use it for their custom projects and it offers great customizability and a user-friendly interface. The robot itself is beginner-friendly and easy to assemble. For instructions, users can visit the HiWonder youtube channel to find a variety of tutorials and instructions for their products. The app is great in terms of functionality, and we recommend the PC software for further customizability. Outstanding product overall and we can tell that a lot of effort was certainly put into this!!

The robot is good in terms that it does what it says. However, it may need some additional adjustments and calibration to work as expected. Also, the bundling and strapping of cables can be improved. What I like the most are the details, the easy-to-follow documentation and the tech support. Recommend buying one of this.

We received this robot and did not immediately have time to assemble. With about 4 days left on the return status we discovered it was not completely functional. None of the servos were working. We contacted Amazon and then the seller via the message center. The seller had me do some root cause analysis steps, most of which I had already done, and it was still not resolved. I suggested that I check voltages as I was getting a power error message on the RaspPi home screen. They had me check voltage of the supply, which was spot on, and the output from the board to the servos, which was 5V instead of 7.4V. They then sent me a new board and power supply and this resolved the issue. As an engineer, I know that having an issue like this is a great teaching tool even if it was a little frustrating and time consuming to resolve. Happy with the purchase!

Broken servo right out of the box. Doesn’t function very well. Not very cool. Definitely not worth the money.

I bought this to learn more about robotics. It has opened up a lot of possible projects. The assembly instructions are written and they also have videos. Took about a half hour to assemble.

No manual included. Assembler video is ok but not clear how to wire the servos. When finally done I downloaded the WonderPi app and the control worked. I had to connect to an unsecured WiFi to use the app, so I cannot use my phone while operating, but often the wifi served from the robot disconnects midway, and the robot keeps moving and spinning out of control.

Good one to explore the robotics , after going throw the videos able assemble. Default image provided has most of the packages needed.

I can't find a guide or tutorial, there's a lot of headscratching. I'll see what happens.
