i just got my omnibot 2000 from JOSH while back and got a chance to take him apart and start the modding first i am working on the base,i am adding tracks with floor inserts,so that he can move on tile floors and carpets.,these tracks are easy to use and add on and can move up to 60 lbs,will be posting photos ,parts lists in a few days software using will be my AI SOFTWARE

my software

i guess will tell you the tracks i am using its from VEX ROBOTICS

vex robotic tracks now if using a floor and carpet or rugs or both

vex robotic tracks upgrade

for up to 60 lb load need 4 motors if 30 lb 2 motors

vex robotic high torque motors

plus frame kit and few parts whats great about this design if you dont want tracks add wheels very simple change so you are looking at a universal wheel design add-on latter are optical feedback this design fits perfect without many changes to omnibot body i have tried lynxmotion tracks,but lot of changes then need to make a track base not universal and not great on floors,i have both track designs
