AIC - Gazebo Friction During Evaluation
A robot arm gets stuck on cables in simulation, raising questions about evaluation fairness.
A competitor in the AI for Industry Challenge (AIC) has raised a critical technical issue that could impact robot performance scoring. On March 30, 2026, user KarlJohannes posted in the competition forum detailing how their simulated robot arm in the Gazebo physics engine gets stuck when a cable lays across NUC (Next Unit of Computing) boxes. The reported problem involves unexpectedly high friction that prevents the arm from pushing the cable down to reach a plug located behind the boxes, potentially hindering task completion.
The post directly questions the competition organizers about whether this specific friction behavior is an intended part of the challenge or if parameters will be adjusted for the final evaluation trials. This query sits among other technical threads about the AIC, including migration to new Gazebo versions and launch sequences for evaluation. The resolution will determine if teams need to re-engineer their control strategies to handle the current physics or if they can expect a more forgiving environment during judging, affecting development timelines and final rankings.
