Toyota Motor Corp.’s new violin robot performs during a press unveiling in Tokyo Thursday, Dec. 6, 2007. Compared to a virtuoso, its rendition was a trifle stilted and, well, robotic. But Toyota’s new robot plays a pretty solid “Pomp and Circumstance” on the violin. The 152-centimeter (five-foot)-tall all-white robot used its mechanical fingers to push the strings correctly and bowed with its other arm, coordinating the movements well

MIT media lab has achieved a new milestone in the field of robotics with the development of a new robot that is able to show various facial expressions such as “slanting its eyebrow in anger” or “raise them in surprise.” It shows wide variety of facial expressions while communicating with people.

Nexi - The Next Generation RobotsScientist has named this advanced robot “NEXI”. The name has been derived from the fact that it is the next generation robot which will be used in a range of applications in personal use especially where a human-robot team work is to be carried.

Designing Features of NEXI

Xitome Design, an innovative designing and development company has designed head and face of NEXI. They are specialized in designing cutting edge robotic design and development.

Neck Mechanism:

The expressive robotics started with a neck mechanism sporting 4 degrees of freedom (DoF) at the base, plus pan-tilt-yaw of the head itself. This mechanism has been made to time the movements so they imitate human speed.

Face:

The face of NEXI is also specially designed to use gaze, eyebrows, eyelids and an articulate mandible which helps in expressing a wide range of different emotions.

Chassis:

Chassis of NEXI has been designed and developed by Laboratory for Perceptual Robotics UMASS
(University of Massachusetts), Amherst. It is based on uBot5 mobile manipulator. It can balance dynamically on two wheels. Arms of NEXI are able to pick a weight upto 10 pounds.

Head of the Project:

Cynthia Breazeal, a famous robotics expert and associate professor of Media Arts and Sciences at MIT is heading the project NEXI. She has worked successfully on projects like Kismet in the past. She named her new product as an MDS (mobile, dextrous, social) robot.

Features of NEXI:

NEXI has many other features except a wide range of facial expressions. It has self-balancing wheels like the Segway transporter, to ultimately ride on. Currently it uses an additional set of supportive wheels to operate as a statically stable platform in its early stage of development. It has hands which can be used to manipulate objects, eyes (video cameras), ears (an array of microphones), and a 3-D infrared camera and laser rangefinder which support real-time tracking of objects, people and voices as well as indoor navigation.
