DEF

Distance traveled divided by the time of travel.

CONT

Velocity is the rate of movement, or more specifically, the distance traveled per unit of time.

OBS

Rate of motion in a straight line is called linear speed, whereas change of direction per unit time is called angular speed. Speed and velocity are often used interchangeably although some authorities maintain that velocity should be used only for the vector quantity.

OBS

Record 2 1999-01-15

English

Subject field(s)
  • Applications of Automation
DEF

A control scheme whereby the velocity vector of the end point of a manipulator arm is commanded and the computer determines the joint angular velocities to achieve the desired result. Coordination of a robot's axes so that the velocity vector of the end joint is under direct control. Motion in the coordinate system of the end point along specified directions or trajectories (line, circle, etc.) is possible. Used in manual control of manipulators and as a computational method for achieving programmed coordinate axis control in robots.
