Omnidirectional Driving Gear

Omnidirectional driving gear that can move curved surfaces with arbitrary curvatures was developed. The omnidirectional driving gear has two orthogonal active D.O.F. on one flat or curved surface.

As ordinary dual-axis driving mechanisms in X-Y directions, for example, commercially available X-Y stages with ball screws are familiar. However, such driving mechanisms have two stages, namely both upper and lower linear actuators, the latter of which must generate sufficient thrust to carry large weights, including that of the upper actuator mechanism, which has hampered efforts to achieve suitably fast and smooth driving motion due to the inertial force effect. It is also difficult to achieve a small and slimline driving mechanism with such overlapping two-stage structure. In these ordinary two-stage driving mechanisms, the motion of the X-Y stage can be disturbed by the wires of the upper actuator. In this research, we have considered the abovementioned problems, and propose a new omnidirectional driving gear mechanism that enhances its driving area from the normal X-Y plane to convex and concave curved surfaces respectively, and even various combinations of both.

Robots that can Work better with Humans

High Speed hands, high speed camera... What happens in your brain when you play with a humanoid robot? What happens if the robot tricks you? In this project we investigate the game dynamics behind that will help us build kinder, smarter, more perceptive humanoid robots. Come to see the robot that never loses to paper rock scissor game. The first academic achievement of this research was released in ROBOMEC2011 conference of The Japan Society of Mechanical Engineers (JSME) in Okayama city.

Lightweight and Soft Humanoid Robot

Nowadays robots made of steel, batteries and industrial servomotors are so heavy that in some cases they cannot even lift themselves from the ground. Their heaviness makes them dangerous. The high-power heavy-motors needed to move them make them even more dangerous. Until now, use of high precision high power open-loop servomotors has been the only solution available to ensure that a robot moved where it was ordered to move. This is the technology used in car factory robots. These factory robots work without eyes and because they are blind they need a very controlled environment to work safely.
But today advances in visual recognition mean that we can use less-precise lighter motors because robots are not blind anymore. The visual robot can adjust better to a dynamic environment. Some companies like FESTO and others have been using air based actuators for a while now. Air based actuators are not so precise but are lighter and compliant, this means that nobody can get harmed by an air actuator.
The challenge: How can we design a cheaper-lighter-safer robot by realizing that we don't need millimeter precision in a humanoid robot?
