Have you used a voltage meter to check what is happening with the voltage?
ps. batteries can seem to have a full charge when unloaded, but when they
have to deliver power the voltage will drop. Is so then
A: your battery need to be re-charged
B: You draw to much current.
C: The battery is defect.

I remember making little boats using steam for power. I used an emptyed
egg shell with a pinhole in one end. This was filled with water and
a candle used to turn the water inside the egg into steam, which shot
out the hole to propell the craft.

This could be a very simple way to propell a robot.
