ROVER is a 4x4 platform designed for an indoor and outdoor operation requiring higher ground clearance and faster maneuverability. When compared with traditional 3 driven platform, the 4WD use four independent drive motor, which makes it more powerful and provide the climbing ability for outdoor applications, this is my final graduation project of industrial mechatronic.
The main goal microcontroller with 8bit, Wifi communication, Wifi and infrared camera, 4x4 platform.
