Robotists from Paris Sixth University have created such a hexapod robot with elastic algorithm, which can run happily for 26 cm per second. Then the researchers cut one of its front legs in half, and it could only run 8 cm per second. However, after 20 minutes of running test and debugging, the "five legged" robot found a unique running method, which increased the speed from 20 cm per second.

General robots are relatively simple in setting. When running on the road, a part will be scrapped if it goes wrong, just like a detector sent to other planets. If it loses contact and mechanical failure occurs, the equipment costing billions of yuan will be ready to be fossilized. So it would be great if these advanced and expensive robots could repair themselves. If they could not repair themselves, it would also be good to think of ways to use existing parts to continue to move forward and not completely scrap.

This robot uses what researchers call "self mode", which is basically to let the robot understand its structure when it is intact. The previous method is to let the robot analyze the efficiency of the new step to diagnose the condition of the broken limb, and then conduct corresponding debugging to compensate the speed. But the team's method is to ask the robot to list a variety of walking plans when intact, try various methods after amputation, and find the one with the highest efficiency. This method is faster to draw conclusions.

The "five legged" robot spent 20 minutes testing 25 different running methods. During this period, the robot's camera provided distance and speed information. The robot found the running method closest to the original speed by comparing the actual situation with the ideal situation.
