The controller disconnects under acceleration

Identify the electrical reset without rewriting serial reconnect logic.

Pairs with Linux devices and electrical evidence in Hardware Integration & CANopen. Read the concept first, then diagnose it here.

Open repair workspace

Operator report

USB disconnects occur only when both motors accelerate hard.

Ubuntu 24.04, ROS 2 Jazzy, SocketCAN vcan, CANopen drive simulator, ros2_control

How this lab works

You diagnose it. No command list.

Open the repair workspace and gather your own evidence in a real terminal. No diagnostic commands are handed to you - finding the fault is the exercise. Stuck? Progressive hints unlock inside the workspace.

Verification

Pass more than the visible symptom.

4 checks
  • No reset at peak acceleration
  • Reconnect logic still passes
  • Hidden regression behavior
  • Root cause explanation
