Claw Machine Drone Graspers
When claw machine meets drone, you get this quadcopter equipped with graspers. Developed by MIT researchers, this soft aerial manipulator boasts a fully onboard perception pipeline, capable of robustly localizing and grasping visually as well as morphologically varied objects.



Put simply, the system consists of a closed tendon-actuated soft gripper that enables fast closure at grasp, while still compensating for position errors, complying to the target-object morphology, as well as dampening reaction forces. An integrated onboard perception pipeline combines a neural-network-based semantic keypoint detector, a state-of-the-art robust 3D object pose estimator, and a fixed-lag smoother to estimate the pose of known objects.

Claw Machine Drone Graspers

We demonstrate fully onboard vision-based grasps of a variety of objects,in both indoor and outdoor environments, and up to speeds of 2.0 m/s—the fastest vision-based graspreported in the literature. Finally, we take a major step in expanding the utility of our platform beyondstationary targets, by demonstrating motion-capture-based grasps of targets moving up to 0.3 m/s,with relative speeds up to 1.5 m/s,” said the researchers.
