Performing manufacturing tasks with a mobile manipulator: from motion planning to sensor based motion control
Résumé
We present a framework combining mobile ma-
nipulation planning and sensor based motion control. The
result of manipulation planning is a reference robot trajectory
composed of segments. For each segment, a hierarchical task
based controller is automatically built. Some of the segments
correspond to motions where some parts of the robot and of
the environment are known to be close to each other. The
corresponding controller implements a task of relative pose
between these elements. The task error is measured by vision
sensors using AprilTags. The higher priority of this task with
respect to the reference joint trajectory greatly improves the
accuracy of the task affected by the poor accuracy of the robot
base localization and other sources of error.
