China's half robot marathon already has pit stops for fresh ice, batteries and WD-40
China's robot half marathon already has pit stops for fresh ice, batteries, and WD-40, and the scene looks less like athletics and more like Formula 1.
At the second Beijing E-Town Humanoid Robot Half Marathon on April 19, more than 100 teams sent bipedal robots down a 21 kilometer course.
Along the route, technicians poured coolant on overheating motors, sprayed lubricant into joints, and carried out hot battery swaps that keep the system running during the change instead of shutting the robot down.
Running a bipedal body that far pushes limits rarely seen in lab demos.
Batteries drain under load, motors heat up, and joints wear under continuous stress. The winning robot, Lightning from Honor, uses liquid cooling with flow above 4 liters per minute and joint modules with 400 Nm peak torque, and it still needed pit support during the race.
