Robotics: Mobility Coursera

Now we'll put physical links and joints together and consider the geometry and the physics required to understand their coordinated motion. We'll learn about the geometry of degrees of freedom. We'll then go back to Newton and learn a compact way to write down the physical dynamics that describes the positions, velocities and accelerations of those degrees of freedom when forced by our actuators.Of course there are many different ways to put limbs and bodies together: again, the animals can teach us a lot as we consider the best morphology for our limbed robots. Sprawled posture runners like cockroaches have six legs which typically move in a stereotyped pattern which we will consider as a model for a hexapedal machine. Nature's quadrupeds have their own varied gait patterns which we will match up to various four-legged robot designs as well.
