High-Access Survey Robot Developed Jointly by Honda and AIST Begins Work at
TEPCO Fukushima Daiichi Nuclear Power Station 
Tokyo, June 17, 2013 - (JCN Newswire) -  Honda Motor Co., Ltd. and the National
Institute of Advanced Industrial Science and Technology (AIST) have jointly
developed a remotely controlled survey robot that will conduct on-site surveys
on the first floor of a nuclear reactor building at Fukushima Daiichi Nuclear
Power Station of Tokyo Electric Power Company, Inc. (TEPCO) and help discern
structures in high and narrow areas. This newly-developed survey robot will
begin working inside the reactor building on June 18, 2013. 
The survey robot was developed to support the actual needs based on
information provided by TEPCO concerning conditions inside the reactor
building. AIST developed the high-area accessible crawler work platform and
Honda developed the survey-performing robot arm, which is installed on top of
the platform. 
In developing the survey-performing robot arm, Honda applied the following
technologies which were developed originally for ASIMO, Honda's humanoid
- Technologies that enable 3D display of structures surrounding the subject of
the survey using a 3D point cloud (a group of vertices in a coordinated
- A control system that enables simultaneous control of multiple joints
- Control technologies which enable the robot arm to absorb the impact when it
makes physical contact with surrounding structures 
With these technologies, the newly developed robot arm can easily approach
hard-to-see objects that are behind other objects in a structurally-complex
environment in the reactor building by applying simultaneous control on
multiple joints. When approaching the objects, the robot uses a zoom camera,
laser range finder and dosimeter located at the tip of the arm to confirm
detailed images, collect 3D data and identify the source of radiation. 
For the high-area accessible crawler work platform applying a structure with a
low center of gravity that enhanced the stability of the robot, AIST applied
its various remote control technologies and ingeniously positioned camera,
lights, laser marker and other devices, enabling it to be remotely controlled
via 400-meter fiber-optic wired LAN and wireless LAN. 
Moreover, Honda and AIST jointly developed an intuitive remote-control
interface. Using this interface, the operator can control the robot from a
remote location such as the Main Anti-earthquake Building and allow the robot
to maneuver in dark and narrow places in the reactor building. Once the robot
reaches a target spot, the mast can be extended to survey areas as high as
seven meters without hitting the robot arm against surrounding structures.

- Maximum allowable bumps: 60mm in height 
While making progress in the development of ASIMO, a humanoid robot that can
be helpful to people while co-existing with people in their daily lives, Honda
also has been studying and researching the possibility of using humanoid robots
at disaster sites. Following the development of this survey-performing robot
arm, Honda will accelerate the development of humanoid robots also designed for
use in response to disasters, including the prevention and mitigation of damage
caused by a disaster. 
In reaction to the Great East Japan Earthquake, AIST has been supporting
recovery efforts in various forms including surveying the situation of
underground seawater seepage in areas affected by the tsunami, leading the
Kesennuma Kizuna Project, conducting and supporting radiation measurement and
decontamination, and volume reduction of plant-based radioactive cesium. AIST
will continue utilizing primarily its robotic technologies to contribute to the
efforts to decommission the TEPCO Fukushima Daiichi Nuclear Power Station.
