In this paper, a novel haptic device is proposed that gives weight and friction illusions. Sensing a slip condition at the fignertip plays an important role to estimate the weight and friction of an object. This fact suggests that controlling the ...
In this research, we propose a producing method of softness sensation using a pinching type tactile device. The producing method of softness sensation which is significant information during the pinching motion by a human is proposed. The basicall...

In this paper, we present a water volume estimation method in various cups using the glass harp acoustics. When a rigid probe flicks a glass, sounds arise. Since the sounds alter depending on the water volume in the glass, we can utilize the sound...

In this research, the slip margin between an elastic object and a rigid plate is estimated based on the analysis of Hertz contact model. A method of the grip force control using the slip margin is proposed. When an elastic object is pressed and sl...
In this research, a novel compact pointing device is proposed which utilizes the deformation of the fingerprint. When the fingertip is pressed and slid slightly on a rigid plate, a partial slip, called "incipient slip" occurs on the contact surfac...
Recently, there is growing interest on recording human motions from first-person perspective in a domestic environment. RGB-D cameras have been widely used in the field of robotics and also in analysis of egocentric vision, and such devices are st...
Recently, cleaning robots are becoming widely used. However, even if commercially-available cleaning robots can collect dust and small debris on the floor, they can not pick up trash such as PET bottles, cans, etc. We developed a cleaning robot in...
Recording manipulation tasks are very useful for teaching-by-demonstration and digital archiving of manipulation skills. In this paper, we propose a method for recording hand-object relationship during tasks using first-person RGB-D vision. First-...
Recently, we have proposed a low-cost and highly reliable monitoring device which is called the MIMAMORI device for a monitoring system at a medical institute. The MIMAMORI device can detect dangerous situations, such as when a patient is at risk ...
