Plant operator Tokyo Electric Power is hoping the iRobot Packbots will be able to provide data on the current condition inside the buildings, parts of which contain high levels of radioactivity and are hazardous for workers to enter.
The robots entered the plant's number 3 reactor building and were due to take radiation and temperature readings. They are equipped with video cameras that can provide a live feed to operators.
Photos released by Tokyo Electric Power (TEPCO) showed one of the robots manipulating a handle on the second of a pair of double doors that lead into the reactor building. ()
