The project focused on the development of a prototype for an electromechanical cable management system designed for unmanned ground vehicles (UGVs). As the use of UGVs continues to grow across industries, the need for reliable solutions for handling fiber optic cables—used for remote control and data transmission—is becoming increasingly important.

The students, Linus Samuelsson and Albin Hammarberg, set out to design a modular system capable of both deploying and retracting fiber optic cables, combined with a scalable control architecture adaptable to different cable dimensions and operational requirements. The result is a highly flexible concept that can be tailored to a variety of applications.

A key innovation in the project lies in the control strategy. The developed control loop dynamically adapts the system’s behavior based on the cable’s properties, such as width and length. By combining a feed-forward model—which accounts for changes in the drum radius during operation—with a load cell acting as a tension observer in a closed-loop system, the students achieved precise and stable cable tension control.

In recognition of Linus and Albins' outstanding work and dedication, Micropol awarded them a scholarship of 15,000 SEK each. This highlights both the quality of the project and the value of close collaboration between academia and industry.
