Telesar V Robot Hints At The World Of Surrogate Robots



TELESAR V Robot

 Telepresence Robots
TELESAR V is a dexterous anthropomorphic slave robot that duplicates the same size and movements of an ordinary human and maps the user's spinal, neck, head, and arm movements. With this system, users can perform tasks dexterously and feel the robot's body boundaries through wide-angle high-definition vision, binaural stereo audio, and fingertip haptic sensations.
In the film Surrogates, a future is imagined where people engage in their day-to-day activities via a robot avatar.  Now scientists at the Japanese Science and Technology Agency (JST) and Keio University’s Tachi Lab have presented their newest telexistence system, the TELESAR V, at SIGGRAPH 2012 Emerging Technologies that could be an early prototype right out of the science fiction film.

TELESAR V is a dexterous anthropomorphic slave   that duplicates the same size and movements of an ordinary human and maps the user's spinal, neck, head, and arm movements. With this system, users can perform tasks dexterously and feel the robot's body boundaries through wide-angle high-definition vision, binaural stereo audio, and fingertip haptic sensations.

The TELESAR V system’s ability to relay tactile sensation has improved since its original reveal last year. In a world first, a human operator can now distinguish if the robot is handling cloth or paper by touch sensation alone.

The operator gets much more than just tactile feedback as part of the experience - a head-mounted display provides a high-definition wide-angle view from the robot’s perspective, along with stereo sound.





The robot avatar’s body has a total of 54 degrees of  freedom (head x3, trunk x5, two arms x7, two hands (and fingers) x16) which allow it to accurately mimic the operator’s movements (using a motion-capture system).

The TELESAR V system is probably the most sophisticated teleprescence robot of its kind in the world today and has the potential for many practical applications. It is exactly this kind of system that will enable humanoid robots to perform complex tasks in hazardous environments, though it will take a second operator to control a robot’s lower body.

The precise controls exhibited by the robot in the video below will probably influence teams competing in the DARPA Grand robotics challenge.  Already, TELESAR's developers Sho Kamuro and Susumu Tachi have expressed their desire for their remote robot to work in dangerous conditions like the Fukishima nuclear disaster.

The Story of the Chessboard


The classic parable of how the inventor of the game of chess used his knowledge of exponential growth to trick an emperor is commonly used to explain the staggering and accelerating growth of technology. The 33rd square on the chessboards represents the first step into the second half of the chessboard, where exponential growth takes off.

33rd Square explores technological progress in AI, robotics, genomics, neuroscience, nanotechnology, art, design and the future as humanity encroaches on The Singularity.
