Robotic manipulation

Definition

Robotic manipulation is the use of a robot to change an object's position, orientation, or state through physical interaction. It includes grasping and moving objects as well as actions such as pushing or carrying them without a grasp.

More than grasping

Picking up a cup is manipulation, but so is sliding it across a table. Modern Robotics distinguishes grasping from non-grasping manipulation and gives examples including pushing, carrying a tray, and moving objects through vibration.

The distinction matters because the robot makes different contacts with the object. The same reference analyses these tasks through contact motion, contact forces, and rigid-body dynamics.

Learning from demonstrations

Manipulation can use two arms working together. The ALOHA 2 project provides hardware for collecting demonstrations of two-arm tasks through teleoperation. Those demonstrations support research into learning robot behaviour from examples.

Handling objects is a specific capability

A humanoid robot may be built for manipulation, but body shape does not establish what it can handle. Check the object, task, contact conditions, and amount of supervision in a reported result. A successful grasp of one rigid object does not establish reliable handling of every object.
