I'm starting a new Robot project after the experience with my first, and small, one.
My goal is to build up a robot base platform to be used to play with SLAM algorithm and image vision. From the experience on my first robot I got this guide lines for this second one:
- get a good control of motors speed;
- high resolution encoders;
- low center of gravity.
To achieve those goal I choose the RD02 drive system (http://www.robot-electronics.co.uk/cgi-bin/sh000001.pl?REFPAGE=http%3A%2F%2Fwww.robot-electronics.co.uk%2F&WD=rd02&PN=Drive_Systems.html%23a5#a5). The chassis base will be hand made from carbon/glass fiber plate.
Here a drawing of my project:
I choose to use omni ball instead caster since the caster can create some uncontrolled move during direction changes. Furthermore I add 4 of them in order to increase the ground base area (increase stability) and to reduce the load on each omni ball.
What do you think about? Do you have some suggestion for me before I start construction?
