Haptic/touch vs. objects moving in space
touching a person vs. moving an object – touch is more personal, requires little energy. Touch can be wrapped in a robotic device, ex: Paro (wiki) trade show demo.
Moving things typically requires an external power source, Arduino can only provide 5V at a few milliamps.
For moving things, use basic physics
- gears — FAQ on 3d printing gears
- levers — drive a lever with a solenoid, transfer short movement to long
- pulleys – drive with DC motors or steppers
