#### Introduction to robotics

lesson

We introduce the topic of robotics, the recent history, why we need robots and the future of robots.

lesson

We introduce the topic of robotics, the recent history, why we need robots and the future of robots.

lesson

We consider a robot with three joints that moves its end-effector on a plane.

lesson

We consider the simplest possible robot, which has one rotary joint and an arm.

lesson

Much of what we know about robots comes from fiction. Let’s look at fictional robots and the underlying reality.

lesson

In this mini-documentary we look at a diverse range of real-world robots, discuss what they do and how they do it.

lesson

For a simple 2-link planar robot we introduce and derive its Jacobian matrix, and also introduce the concept of spatial velocity.

lesson

We consider a robot with four joints that moves its end-effector in 3D space.

lesson

We consider a robot, which has two rotary joints and an arm.

lesson

For a redundant robot the inverse kinematics can be easily solved using a numerical approach.

lesson

For real robots such as those with 6 joints that move in 3D space the inverse kinematics is quite complex, but for many of these robots the solutions have been helpfully derived by others and published. Let’s explore the inverse kinematics of the classical Puma 560 robot.
