I had seen a episode on discovery in which a robot tries to walk even
if legs are twisted. Can we program such robot to look for electrical
energy when battery is low?  For example, robot should detect presence
of live wire, appropriate voltage in wire and charge itself. As live
wire has electric(magnetic) field, may be it is possible to program
robot.

That will be a breakthrough in understanding origin of life.
