What are the joints of a robot?
The joints (also called axes) are the movable components of the robot that cause relative motion between adjacent links.
What is joint variables in robotics?
The joint variables define the configuration of the manipulator by specifying the position of each joint. The end effector coordinates define the position and orientation of the end effector. The next subsection will address this dependence and analyse the kinematics of robot manipulators.
What is the purpose of robot joints?
A robotic joint provides relative motion between two links of the robot. Each joint, or axis, provides a certain degree-of-freedom (dof) of motion.
What is the home position of a robot?
Home The Home position is a position away from the workpiece transfer area, or the area where work is being performed. It is very common to program the robot to move to the Home position before the first position in a program, between cycles, and at the end of an application program before powering down the controller.
What kind of coordinate system does a robot use?
A robot’s TCP position is specified in a Cartesian Coordinate. A Cartesian Manipulator is a robot arm with prismatic joints, which allows movement along one or more of the three- axes in the X, Y, Z coordinate system.
Which is an example of a power mechanism in robotics?
A power mechanism used to effect motion, or maintain position of the robot (for example, a motor which converts electrical energy to effect motion of the robot) (R15.07). The actuator responds to a signal received from the control system.
Which is an example of a jointed manipulator?
A manipulator with an arm that is broken into sections (links) by one or more joints. Each of the joints represents a degree of freedom in the manipulator system and allows translation and rotary motion. Describes a jointed device, such as a jointed manipulator.
