Cursor in Action

Components

The system consists of

Power circuit

The Chariot as well as the FPGA Board are powered with the power circuit located on the cursor chariot.

DC motor

The DC motor is controlled by a L6207 H-bridge driver.

Encoder

The position of the screw can be detected with help of the incremental encoder module

Toplevel Design

There is a Empty and a Demo Toplevel Design. the Empty for the Students to create their own system and the Full is our example.

Specification

  • On reset the cursor moves to the end of the chariot
  • By pressing the pos 1 button the cursor need to move to position 1 with an acceleration and deceleration phase
  • By pressing the pos 2 button the cursor need to move to position 2 with an acceleration and deceleration phase
