How to keep pixace controlled robot from getting stuck?


I have built my first robot after advice of  LMR start here. So my robot is navigating with help of IR sensor and has those standard geared motors.

 I'm wondering if picaxe can read information from motors if the robot gets stuck. I guess motor makes some noise in such a situation?Can pushing against some obstacle with rubberwheels on harm picaxe?

I would be grateful for any piece of advice!

Two ways:

Monitor the current draw of the motors. When they get bogged down or stall, they will start sucking a lot of power. The other option is to use some encoders on your wheels. If the motors are on and your encoders are not moving, you are stuck.
