first of all i would like to say hello to the LMR crowd and thank fritsl for creating this nice place where we can all share our robot experiences and have fun.
that being said let's talk about robots.
i used rhino3d to design the frame which is based on the tamiya twin-motor gearbox(#70097) and the track&wheel set(#70100).
the parts for the frame are cut from a sheet of 3mm MDF with the help of my robot slave(cnc router). they fit together with tabs and slot and are glued with wood glue.
the electronics consist of
the brains: atmega168 - bascomavr
motor driver: L293DNE
servo: hextronik HXT900
sensor: sharp GP2D12
power: 2cell lipo 7.4v and LM2940 5v 1A low dropout regulator
and are put together on a perfboard.
more to come...
