Robotic Terms Flashcards
What is the definition of a robot?
An electromechanical device with multiple degrees-of freedom (DOF) that is programmable to accomplish a variety of tasks.
What are the 2 types of robots?
> Manipulator
> Anthropomorphic
What is a manipulator?
Electromechanical device capable of interacting with its environment
What is an anthropomorphic robot?
A robot that looks and acts like a human being
What does DOF mean?
> Degrees of freedom
> the number of independent motions a device can make. (Also called mobility)
What is an endeffector?
The tool, gripper, or other device mounted at the end of a manipulator, for accomplishing useful tasks.
What is the work space?
The volume in space that a robot’s end-effector can reach, both in position and orientation.
What is the definition for position?
The translational (straight-line) location of something.
What is the definition for orientation?
The rotational (angle) location of something. A robot’s orientation is measured by roll, pitch, and yaw angles.
What is a link?
A rigid piece of material connecting joints in a robot.
What is a joint?
The device which allows relative motion between two links in a robot.
What is kinematics?
The study of motion WITHOUT regard to forces
What is dynamics?
The study of motion WITH regard to forces
What is an actuator?
An element of a robot that provides force for robot motion.
What is a sensor?
Reads variables in robot motion for use in control
What is speed?
Distance per unit time for a robotic movement
What is the load baring capacity?
The maximum weight-carrying capacity of the robot
What is accuracy with regards to robotics?
The ability of a robot to go to a specific position without making a mistake
What is repeatability with regards to robotics?
This is the ability of a robot to repeatedly position itself when asked to perform a task multiple times.
What is kinematics?
The geometry of motion
What is forward kinematics?
Finding the end effector location from the angle of joints and lengths of links
What is inverse kinematics?
This is finding the angles of the joints whilst knowing the end effector location and angle of it from the horizon and lengths of links
