Robot having internal heat problem

It's a small robot my son assembled and is operated by a small battery... so some of the more sophisticated energy consuming techniques won't work.

Thanking everyone in advance.

Bigger heatsinks (maybe even a large brick of copper) & more fans, mainly, if you can get a proper air flow going over the hot spots then that'll pretty much fix the problem. If you can't power a fan, I suppose you could try using copper heatpipes to channel heat to a heatsink outside of the robot?
Dry ice might work. It runs out, though. And putting dry ice or turning a duster can upside down and spraying hot spots can create thermal shock, which is generally bad.

Hope this helps.
