Tool Center Point

  • This is the geometrical center of the clamps at the end of the effector

moveJ (Joint)

  • this is called Joint Motion
  • it is used when the path of motion is not important
  • such as in free space

moveL (Linear)

  • linear straight motion from 1 waypoint to another
  • pick or place an item
  • path of TCP is important

moveP(Process)

  • somewhat similar to moveL
  • but it moves at constant speed throughout
  • good if the arm is a process of releasing glue and we want it to be constant pace
  • a normal straight path from A to B, like a corner of a rectangle, becomes a rectangle with rounded edges
  • the curve at an edge is called Curve Radius
  • we need waypoint A (starting), via waypoint (which is the midpoint the motion will pass through), and finally waypoint B (which is the ending waypoint of the motion)

Degree of Freedom (DOF)

  • to see if a joint or link is able to move, that will produce a unique point in space
  • for UR5E, 6 dof
