Microspines Make It Easy for Drones to Perch on Walls and Ceilings
Morgan Pope is a PhD student investigating robots that live at the boundary of airborne and surface locomotion at Stanford’s Biomimetics and Dexterous Manipulation Lab. He wrote about SCAMP, a flying and perching robot, for Automaton earlier this year.
A disaster site. A rainforest. A battlefield. These places have something in common: we have a need to understand what’s going on where established infrastructure can’t give us good data. Advances in computation, fabrication, and materials over the last half-century have resulted in small, cheap, and lightweight sensors that can provide us with these data; now the task is to find ways to deploy such sensors rapidly and effectively.
One way to do this is with small, agile aerial vehicles like quadrotors. Quadrotors are becoming affordable, ubiquitous platforms that can fly quickly over rugged terrain to collect critical data. There’s a catch, though: most small (less than 1 meter in diameter) quadrotors can only stay in the air for tens of minutes at a time, and this limited endurance makes some missions unachievable. However, if the goal is to collect data from a fixed vantage point, there is an alternative to hovering in place that might extend mission life from minutes to days or even longer: perching.
