I've bought a floppy fish toy (crab version) for my kid. The toy looks like:
Unfortunately, the toy mechanism inside jams when grabbed and the battery lasts for a short time:
I tried to do my own mechanism, printing own case and using Arduino with servo PowerHD R12 but the servo was heating up :( Is there any possibility to make similar mechanism for toy with not oversizing it? What kind of motor/mechanism would be good for that kind of sweeping toy so it doesn't get hot?
EDIT: what type of motor/servo would fit for this kind of mechanism? I tried few servos and notices that desired speed would be minimaly 0,06 [s/60sec] and momentum 8 [kg*cm].
