Here is another Raspberry Pi robot for more advanced students. The Yahboom Raspberry Pi Robot Tank (Transbot) comes with a Silan A1 LiDAR that can be used for 2D scanning and mapping. This robot can be programmed to detect faces, recognize objects, automatically drive, and navigate your home.
You can program this robot with your smartphones and a joystick. The robot has a HD camera with an electric rotating pan/tilt function. The Transbot is ready for Python and C++ programming. It is powered by a quad-core ARM A57 processor with a 128-core NVIDIA Maxwell GPU.
