摘要:
The contact sensor includes a conductive fabric, an insulative spacer having multiple openings, and a conductive sheet of a sheet-shaped conductor. The insulative spacer is interposed between the conductive fabric and the conductive sheet. Upon contact of a soft object such as a human body portion on the conductive fabric with force equal to or greater than a certain strength, the insulative spacer sinks in the soft object with the conductive fabric interposed therebetween. The conductive fabric is deformable in conformity with insulative pieces of the insulative spacer, such that touching of a portion of the conductive fabric on the conductive sheet provides detection of contact of the soft object.

The joint mechanism includes a first link, a second link, a third link, a shaft supported on the second link to be rotatable about an axis thereof, and movable in an axis direction thereof, a first worm and a second worm mounted on the shaft, a first worm wheel in mesh with the first worm to pivotally move the first link with respect to the second link, and a second worm wheel in mesh with the second worm to pivotally move the third link with respect to the second link. The first link and the third link are pivotally moved in opposite directions to each other by rotating the shaft, and pivotally moved in identical directions to each other by moving the shaft in the axis direction.
摘要:
A manipulator is provided with a first link, a second link, first and second differential input shafts rotatably supported on the first link, a differential output shaft rotatably supported on the second link, a differential gear mechanism for rotating the differential output shaft about two axes orthogonal to each other in accordance with the sum or difference of rotating speeds of the first and second differential input shafts, a first transmitting portion for transmitting a driving force to the first differential input shaft, a second transmitting portion for transmitting a driving force to the second differential input shaft, a first shaft rotational angle sensor for detecting rotational angle information of the first differential input shaft, a second shaft rotational angle sensor for detecting rotational angle information of the second differential input shaft, and a controller for detecting the reception of an external force by the first or second link based on an output signal of the first or second shaft rotational angle sensor. Each of the first and second transmitting portions includes a rotatable worm elastically held at a specified position in such a manner as to be movable in a translation direction of a rotation axis and a worm wheel engaged with the worm. The worm makes a translational movement in accordance with the external force received by the first or second link.
