Prototype and Design of Six-Axis Robotic Manipulator

The paper presents a design for a six-axis manipulator. The design consists of specially designed solutions for housing, planetary gearboxes, and electronics. The manipulator is controlled by a supervisory control system. The use of a series of measuring elements allows tracking of the current position of each axis. This can be used to create a cascade control loop with velocity and acceleration feed-forward. The implemented control algorithm together with the microcontroller software allows one to tune parameters of the controllers for both control loops: inner, related to the speed of the robot; outer, related to its position.
