- when do you use Lego motors?
- Mounting motors
- What can go wrong
- Supporting servos and motors
- Need low center of gravity
- Battery management and electrical issues
- Recharging batteries - get a quick charger
- Watch for shorts
- Use heat-shrink tubing if allowed (check this)
- Careful cable routing - cables are rather stiff
- Are more flexible wires available?
