Development of Four Legged ROBOT by Toshiba
As the recovery works continue at crippled Fukushima No.1 Nuclear power plant the officials in charge of the investigation and recover work are working hard to find a way to minimize the risk for individuals working at the plant which makes use of robots as an indispensable solution to carry out this operations. One company which has been involved in developing such solution is Toshiba which has developed a tetrapod (four-legged) robot to carry out such type of missions. The new robot comes with an integrated camera and dosimeter capable of investigating the condition of nuclear power plants by remote-controlled operation.
The multiple joints of this robot’s leg are controlled by a dedicated movement algorithm enabling the robot to walk on uneven surfaces and avoiding obstacles as well as climbing stairs and securing access into areas which would be difficult by wheeled robots or crawlers. The new robot also comes with a folding arm capable of releasing a smaller robot which can carry a second camera, where it can be launched from the main robot and positioned to take images of narrow places and any equipment behind them, plus tubes and other places that are too small for the robot to enter. The smaller robot is connected to the main robot via a cable. The main robot weighs 65 kg with a form factor of 624 (L) x 587 (W) x 1066 (H) mm. It is battery powered which can run continuously for 2 hours. The robot has a walking speed of 1KM/h. The second camera weighs 2 kg with form factor of 313 (L) x 327 (W) x 47 (H) mm, also battery powered which runs for 1 hour and speed of 200m/h.
