Abstract: The disclosure includes an input unit for robot operation having a base, a contact part which is rotatable with respect to the base and with which an operator's finger makes contact. A detection unit can detect the amount of rotation of the contact part with respect to the base. The contact part is configured to: rotate in a first direction about a first axis with respect to the base and in response to flexion of the finger; rotate in a second direction about the first axis with respect to the base in response to an extension motion of the finger; rotate in a third direction about a second axis with respect to the base in response to adduction of the finger; and rotate in a fourth direction about the second axis with respect to the base in response to abduction of the finger.

Abstract: The motion detecting device that detects motion of an operator's finger for remotely operating a multi-articulated robot includes a device main body that is installed such that the finger is placed thereon, a contact part that follows a shape of the finger in the device main body and is in contact with the finger, and a detection part that detects the motion of the finger on the basis of a pressing state of the finger against the contact part.
