Trolley speed control

Imagine that you want to have a kind of "automated control" for a trolley (i.e. a golf trolley). What kind of automation system would you use?

The basic requirements would be the follwoing ones:

- Trolley is stopped, you push it and it starts due to the force of the push.

- The trolley accelerates in order to reach the speed at which you're walking.

- When the trolley is having the same speed than the person walking behind it the force on the trolley handle is almost nul and the trolley runs at this speed.
