Reading articles on robot competitions makes me really envious! :) I don't know of such competions in South Africa , sometime I feel quite alone here. Are there any other South African robot enthusiasts?
After adding my large castor wheel I sit with a balancing problem where my centre of gravity on the MACH 2001 is more over the main drive wheels than towards the castor so I may have to rebuild the robot. One great mission so I'm still pondering over a better solution.
At this stage at work we are looking at SUSE LINUX and who knows maybe the operating system on the MACH 2001 might just become that? We should get the professional package this afternoon!
