Ok... The stopping thing, that's lack of power - batteries flat, weak motors, heavy robot. Maybe wheels too large. The switch error - that's wiring. I can't see what you've connected where, but I am strongly tempted to tell you to desolder everything and start again, going slowly.

Wheels

Pinch them off a toy car, or make them from a pair of identical bottle-lids filled with epoxy. Use rubber-bands as tyres for grip.

If the shaft of the motor is very smooth, scratch it with a file or roughen it with sandpaper to make glue stick.

getting on and off

If it is switching on and off as you handle it, then something is loose - either a joint is not very solid, breaking the circuit occasionally, or there is a short - a bit of wire or metal connecting bits that shouldn't be connected.

Do your batteries get warm even if the bot isn't running? Then it's a short, quick, take out the battery before it melts the holder (I've seen that happen) and check your wiring.

(If that doesn't help, maybe post a photo of the wiring?)
