Well, if you mean the motor can't move the robot because its not strong enough. Then yes, you will need to upgrade the motor or reduce the robot weight.

I change the gear ratio from 58:1 to 208:1 , resulting in a higher torque and lower rpm. Problem solved  :)

What is the recommended way for bi-directional communication (wireless) with user controller ? i need to get some data from mobile robot while asking the robot to do some job.
I need some circuit/schematics .
Thank you !

For wireless it is best to buy RF modules as designing and building them is not trivial. If you need bi-direction communication then the choice is either modules with full bi-directional capability or modules on different frequencies one to send to the robot and one to receive from the robot.

SparkFun has various RF modules that would work.
