Rotorcraft perching, recovery, and takeoff
|This project seeks to adapt what we have learned on climbing robots and fixed-wing perching to enable small rotorcraft to easily land, attach, detach and move along walls, ceilings and other surfaces in intermittent contact. The project is supported partly under ARL MAST (MCE 13-4.4) and by the National Science Foundation (IIS_1161679). We are collaborating with Vijay Kumar's GRASP lab, Prof. Sean Humbert's lab at U. Maryland and with Russ Tedrake's lab at MIT. We use a dynamic high-pitch-rate maneuver to allow us to perch using an undercarriage-mounted gripper. This allows us to also use our adhesives for grasping tasks.|
Recent work has enabled us to distinguish between success and failure using only the onboard accelerometer as feedback. We can then initiate a recovery routine. To determine what signals distinguished success and failure, we used a machine learning algorithm. After dozens of ballistically launched trials, we converged on a set of markers that distinguished between success and failure with 90 percent accuracy within 40 ms of impact. We extracted the most important feature from this algorithm and implemented it on the Crazyflie quadrotor. In twenty trials, fifteen of which were failures, the algorithm correctly differentiated between success and failure every time. The recovery routine halted downward motion after, on average, an 80 cm drop.||
