PowerBotix power supply systems allow robot batteries to be hot swappable, so a robot could change its own batteries.
August 31, 2011 – rChordata announced its PowerBotix line of power supply systems that allow robot batteries to be hot swappable, reducing or eliminating system downtime. The PowerBotix system also intelligently communicates with an onboard computer allowing for better mission planning. Because a robot never loses power to its internal CPU or other components, it could change its own batteries.
