10 Robotic manipulation - goal Automate manipulation Machines that can manipulate like human/animals

11 Robotic Manipulation cutting-edge research has started to shift towards  the development of planning algorithms built upon  the kinematic and dynamic models of the manipulator and  its interaction with the environment. You need to know  not only about the kinematic, dynamic and control of robotic systems  but also the algorithms as well as their computational complexities.

12 Robotic Manipulation - this course We will cover the manipulation of rigid bodies with rigid manipulators. Review  Rigid Body Dynamics and  Manipulator Kinematics. Mechanics of Manipulation  contact models,  friction and statics  static and quasi-static models of interaction between the manipulator and the environment.  force- and form-closure in grasps  measures on grasp stability and quality. Planning  configuration space approach and  planning algorithms for robotic manipulation.

13 Background requirements Open to all engineering students Will need to cover  Calculus  Linear algebra  Programming - MATLAB
