Joint

How it is used

Used in kinematics, programming and specifications. Joint angles, joint limits, joint speed and joint coordinates are common phrases. In programming, a 'joint move' means each axis goes directly to its target angle instead of following a straight line.

Example sentences

1. Jog the robot in joint mode until the wrist is clear of the fixture.

2. The joint limits are set in the controller, so the arm can't damage its own cables.

Common collocations

• joint angle
• joint limit
• joint move
• joint coordinates
• revolute joint

Related terms

• axisOne controlled direction of motion, either a rotation or a straight-line movement, driven by its own motor. Also a line in a coordinate system, such as the X, Y or Z axis.
• robot armThe moving mechanical part of a robot, made of links connected by joints, that brings the tool at its end into position. Technical texts also call it the manipulator.
• degrees of freedomThe number of independent ways a robot or a body can move. A typical industrial arm has six, enough to place its tool at a chosen position and orientation within its workspace.
• kinematicsThe study of motion without looking at the forces that cause it. In robotics, it describes how the joint angles relate to the position and orientation of the tool.
• linear moveA robot motion in which the tool center point travels in a straight line from its current position to the target, at a programmed speed.
