This is a project to make a six-wheel robot with Arduino and Raspberry Pi.
It consists with

  • Six-wheel car platform
  • Dual VNH3SP30 Motor Driver Carrier MD03A
  • Battery
  • Arduino
  • Raspberry Pi
  • Wifi module
  • camera

Hardware architecture

system_hardware

Software architecture

Architecture with node.js

This is the planned architecture. However, there was a problem with Socket.IO in C++ so the next simple architecture was used. system_software

Architecture without node.js

Since there was a problem, C++ process directly sends serial command to Arduino. The disadvantage of this system is that we can't control the robot remotely. system_software2
