A New World Record in Production Quadruped Robots - Field Test of AlphaDog C-Series
Speed Test is one of the most essential performance tests for quadruped robots, especially for general purpose quadruped robots. Because speed test shows its fundamental motion control performance, which is the key difference from wheeled robots and flying robots. Plus, motion control performance is what matters to quadruped robots' daily usage for every user. Unless you are expecting your quadruped robot to take a job in a circus, only then show-off movements may matter that much, otherwise you should look at its walking/running performance. If one can dynamically control the quadruped robot reliably in fast walking/running motion, it proves its sophisticated motion control technology. And that's what we are going to show you.
Before presenting the video, there is still one thing to explain here. What does this specific 3 m/s world record mean for production quadruped robots? Unlike robots in research labs or customized situations, production robots need much more consideration in robustness, functionality and cost-effectiveness, which make it much harder to reach high speed. Like cars, even the best production Bugatti, Ferraris or Lamborghinis nowadays won't reach 500 km/h and most other production cars never will, customized cars like ThrustSSC achieved a speed of 1,228 km/h in 1997.
Among production quadruped robots, the U.S. pioneering quadruped robot company' quadruped robot can walk at 1.6 m/s. Although it's highly advanced, it's not for sale and it's very expensive to rent. And most other production quadruped robots also can't go beyond 2 m/s. A Chinese company claims its new largest quadruped robot can reach 8 km/h, which equals to 2.22 m/s. But this big robot is ten times more expensive and it's a 100 cm long, 60 kg weight big fellow. This very company also has a similar-sized (60 cm in length) quadruped robot which tops at 1.39 m/s. The AlphaDog C-Series we are going to show you is 48 cm in length and 12 kg in weight, which is the best size for most users to get started with. And it's very cost-effective without the compromise on performance.
