Robotic
Personnal project




Quad robot:


The goal of this persnnal project is to realise my own quad robot. I am only computer scientist... So I tried to find a simple way to build the physical part of the robot. You will find on this page the different step of the construction. For the controller, I use an arduino board.

Video:

Second version... The controller was improved to dectect the obstacles.

Specification of the robot:


I would like to make an autonomous robots thanks to distances sensors with:
4 indendant wheels
Max-speed of the robot: 1m en 3,6s
IR sensor: range 17cm-2m
Ultra-sonic sensor: range 3cm-4m
Mini wireless camera
Arduino board
Bluetooth communication (in project)
XBee communication (in project)
