PERPETUAL MOTION – 21152
“motion that continues indefinitely without any external source of energy; impossible in practice because of friction.”
Perpetual motion describes “motion that continues indefinitely without any external source of energy; impossible in practice because of friction.” It can also be described as “the motion of a hypothetical machine which, once activated, would run forever unless subject to an external force or to wear”.There is a scientific consensus that perpetual motion in an isolated system would violate the first and/or second law of thermodynamics.
WRIST-FORCE SENSING – 21151
Several different forces exist at the point where a robot arm joins the end effector. This point is called the wrist. It has one or more joints that move in various ways. A wrist-force sensor can detect and measure these forces. It consists of specialized pressure sensors known as strain gauges. The strain gauges convert the wrist forces into electric signals,which go to the robot controller. Thus the machine can determine what is happening at the wrist, and act accordingly.
