NEO by Stephen Mounioloux

NEO is a six-legged Robot. I started the design 9 months ago but I already had my ideas before. I wanted a
robot able to walk autonomus in a perimeter where NEO would be able to find its way. NEO is totally made of
aluminium : in fact, aluminium is heavy but it has good mecanical caracteristics... Moreover, aluminium is not
difficult to operate. Before machining any piece, I drew totally NEO. I reflected that the movement won't be
very plaisant with my first idea. It came me an idea : every leg should be able to move horizontally when the
legs are brought back and the robot moves forward. So every leg owns three degrees of liberty : to take up the
leg (translation) ; to move forward/back the leg (rotation) and to move left/right (translation). The two first
use one servo each one and the last one don't use any extern power, only the horizontally force of movement.

NEO use so 12 servos only for the movement. 2 other servos are used for the video camera. It can move
right/left or up/down. It's a black and white video camera and next to that I add an Infrared object detection
system. So for example, when NEO find an object in front of him, he can turn the "head" instead of turning
totally to find his way.

His features are overall :
- NEO can be put in a box of 600 x 550 x 400 mm for a weight of 9 Lbs.
- The power supply : 12V / 1200 mAH (for electronic and video camera) & 7,2V / 1900 mAH (for servos).
- 14 servos (Futaba and Hitec).
- A SX 28 DP micro-controller.
- 2 serial servo controler.
