One robot powering another is a small step towards symbiotic, robotic relationships out in the wild. A quadruped robot can’t see very far in front of it, but a quadcopter above could do the job ten times better. That seems to be one future application of the above combo.
Though there’s not a whole lot information about the duo, it appears to be the StarlETH quadruped robot from the Legged Robotics Autonomous Systems Lab at the Swiss Federal Institute of Technology Zurich. The quadruped includes legs specifically designed for different gaits, helping it maneuver about.
Any specific purpose for the two is speculation, though the obvious use for a quadcopter is to see things from above. Getting the lay of the land to all sides of a quadruped could help the four-legged ‘bot run about even better.
If nothing else, it’s interesting to imagine the different ways other robot pairs could support each other. And the possibilities of an untethered version of the quadcopter? The sky’s the limit.
