Dear mister_e,

Thank you for your help. Up to now the robot is walking forward and backward as well as left and right. That is controlled remotely by either remote control or PC (LABVIEW) via wireless communication. That robot can speak as well. It is supported with obstacle finder. Also, in stand-alone mode it can detect any motion for humans and generate an alarm as sort of security.

What else I can add.

Yours,
Bakari
