First one is Robotics Vision, the second MOOC of Peter Corke. He is an Australian roboticist known for his work on Visual Servoing, field robotics and the MATLAB Toolboxes for Robotics and Machine Vision. The course is focus on Artificial Vision for Robotics and it is based on some chapters of his book 'Robotics, Vision & Control'.
Second course is How stuff moves (III): Wave calculus, in it how oscillating systems move is explained. This is the third part of the 'How stuff moves' series, part 1 examined linear motion while part 2 examined angular motion. Although the third part is not directly related to Robotics, it is good to complete the full series to understand the mechanics of all types of physical systems.
