I had my internship in China's Silicon Valley - Shenzhen. The company I worked for was SZOIL - Shenzhen Open Innovation Lab.
One of our projects was creating a Donkeycar. The documentation for it can be found online here. Following the guide to install the hardware and software it would seem to be simple, however with the compatibility with IOS, the files not showing and the WiFi cutting out when downloading dependancies, it deemed much harder.
Donkeycar is a project that upgrades the components of an normal RC car to allow for self-driving capabilities. It includes an addition of a camera which allows the vehicle to learn the track and teach it to drive around without crashing or crossing the track lines. The Raspberry Pi is used to control the vehicle through SSH or WiFi and allows for additional motor modules to be added.
In this video my team and I describe the process of White-label products. It was more of a comical video than one describing all the processes. Nonetheless it gave a great insight into the markets inside Huaqiangbei.
