What's on the Cutting Edge of Technology
The Twendy-One model robot, designed at Waseda University, Tokyo, weighs in at 245 lb, stands almost 4’10”, and has forearms that can support up to 75 lb. A six-axis force sensor lets the robot grasp objects both delicately and robustly, and 12 ultrasonic sensors detect objects to keep people safe.
C-3PO’s Great Grandfather
Robots have been integrated into industry for decades, but
haven’t been brought into homes as useful appliances yet. Work at the Shigeki
Sugano Laboratory, at the Department of Modern Mechanical Engineering, in the
School of Creative Science and Engineering, of the Waseda University, Tokyo,
Japan, may be bringing the day of the ’droids one step closer.
Twendy-One is a nearly-anthropomorphic
human-symbiotic-robot designed to support human daily
activities to fill the gap in labor in the care of members
of aging societies in such chores as human safety assistance
and manipulation.
The Twendy-One model robot has high-output actuators with the
passive impedance mechanisms that let it manipulate objects with various shapes.
It can adapt to human motion and support a human. The robot has the demonstrated
ability to pick up a paper cup as well as assist a person out of bed and into a
chair.
The robot, weighing in at 245 lb, stands almost 4' 10" has
forearms that can support up to 75 lb, with shoulders and elbows with four
degrees of freedom. The hands have four fingers with almost the same range as a
human’s. In the finger tip, a six-axis force sensor and distributed force
sensors let the robot grasp objects both delicately
and robustly.
It has 12 ultrasonic sensors and a six-axis force sensor to
detect nearby objects and humans to keep people, and its environment, safe.

Ford is Exploring and Applying Nanotechnology
Ford scientists are embracing nanotechnology in developing
paints, plastics, light metals, and catalysts that let Ford reduce vehicle
weight and improve fuel economy without sacrificing quality.
Ford powertrains already are benefiting from the company’s
grasp of nanotechnology and mircomechanical properties. A Ford study, "Atoms to
Engines," looked at the structure of cast aluminum alloys at near atomic levels.
From this work, a detailed analysis of the structure/property/process
relationship of the aluminum alloy engine blocks led to reduced engine weight
and, in turn, increased fuel efficiency.
The technology has let the automaker pull
10 percent in structural performance out of Ford engines,
which translates into weight and fuel economy savings.
Ford’s European research lab in Aachen,
Germany, is developing a thermally sprayed nano-coating that
could replace the heavy cast iron liners that provide wear
resistance in cylinder bores in aluminum block engines. This
thin wear-resistant coating reduces weight and improves
friction performance while delivering durability and
reliability equal to traditional bore linings.
Nanotechnology also is being tapped by Ford scientists to
help develop smarter solutions to energy storage issues for
alternative power sources such as lithium-ion batteries and
fuel cells.
