Semi-autonomous soldering robotic arm

Robotics course · team project

The goal was a system that automatically solders predetermined points on an electronic circuit board.

• A Raspberry Pi computes the joint angles for each soldering point and sends them to the robot controller as UDP packets over Ethernet.
• The Mitsubishi industrial arm is programmed with RT Toolbox 3 to move through the received positions.
• A stepper motor (L298N driver) feeds solder wire at each point; LEDs show the system state.
• The solder wire tube and soldering iron holder were designed in SolidWorks.

In the final run the system soldered the target points on a perfboard end to end.
