How to make 3_wheeled Mousey the junk bot?


Hi Im kinda new to robotics and I want to make a 3-wheeled Mousey the Junkbot. https://www.instructables.com/id/Mousebot-Revisited/?&sort=ACTIVE&limit=40&offset=360
I would like it to have 3 motors because i want to put it in an alarm clock.I would also like for it to have a back bumper. Any help is appreciated.

Why does it need three motors? Why not just add a third free-wheeling, er, wheel?

because it wouldnt have enough power to move the clock
So just use larger motors, or gear motors.
