Ghost Robotics' Minitaur Demonstrates Impressive New Skills

For more details, we spoke with Kenneally and De, along with Ghost Robotics CEO Jiren Parikh. IEEE Spectrum: How does a legged robot like Minitaur compare to robots with wheels or tracks? Ghost Robotics: On flat surfaces with no objects in their path, wheeled robots are more efficient than tracked, legged and even aerial robots. In sand, mud and rougher terrain, tracks are superior to wheels. However, with fixed objects, obstacles and vertical surfaces in the path of a tracked robot with no alternative path, legged robots are superior. Even if moderate objects and obstacles can be overcome by tracks, continuous unstructured terrain over a large field of operation reduces the energy efficiency of tracked devices when compared to dynamic legged robots. Another advantage is that legged robots typically have a lot more actuated degrees of freedom than similar sized tracked or ...
