This is what I was looking for. I just need to learn how to free form the components. It shouldn't be too complex, but I am still a beginner.


Thanks to all who replied!

Well, in theory you simply find a solar panel that it can feed from (it has 3V, or am I wrong?) and use it simply instead of the batteries. Or for a more sophisticated version you can use the solar panel to charge the batteries. HOWEVER, if I'm thinking of the right toy (a small cockroach style thing with a sort of rubber brush underneath), the bug is quite sensitive even to changes of the brush position after being squashed in a pocket, and adding extra weight will change his pace terribly, if not totally immobilize the poor soul, as solar batteries don't come small (they need a big area, don't they?!).
I would try to stick different weights to the bug, and if it can carry at least 5 grams, then think further.
Good luck, G

The nano runs on 1.5 volts, so if you found a small solar panel and soldered it to the leads where the battery waswith enough light you could make the nano move.

Note: If you do this please make sure you remove the battery because they are not rechargeable.
