High Access Survey Robot

Category: Robotics > Characterization and Inspection > Wheeled/Tracked System
Reference # : Model No :

The survey robot consists of a mobile platform developed by AIST that carries a robot arm developed by Honda which can be extended up to 7 meters (23 ft). It is remotely controlled via a 400 meter (1300 ft) fiber-optic LAN cable and wireless LAN workstation from inside a separate building. The 1,100 kg (2425 lb) robot travels at up to 2 km/h (1.24 mph) and can overcome 6 cm (2.3 in) bumps. The two groups also co-developed the remote control interface used by the operators.

Using a combination of cameras, laser range finders, and dosimeters on the tip of the extendable arm, operators can see detailed video images, collect 3D structural data, and identify sources of radiation from areas that would be otherwise inaccessible. The arm has 11 joints, allowing it to curl up while the robot is moving to stay out of the way, and snake between pipes during inspection.
