SCARA Robot Basics: Four Axes, Motors and Grippers | Lesson 1

How does a SCARA robot pick up a part, move it across a table and place it with precision? Follow one complete task and see what each part of the robot does. In the first lesson of our SCARA mechanical engineering course, we explore the base, arms, four axes, motors, bearings, vertical drive and gripper. Animated 3D views and simple examples connect the mechanisms to the motion you see. You will learn how J1 and J2 set horizontal position, how J3 changes tool height and how J4 turns the tool. We also work through link geometry, workspace limits, transmission ratios, lifting torque, stiffness, accuracy and repeatability.

Dimensions and calculations are examples, not specifications for a particular manufacturer's robot. Next in the course: designing the base, column and arms.
