Meet Sweep: a scanning LiDAR sensor for drones and robots that allows them to map and navigate their environment and avoid obstacles. It adds 360-degree sensing capabilities to your robots. Sweep can be used to create a virtual curtain and track people within a space.
Sweep has a max range of 40 meters. It could prove useful for students studying navigation and mapping problems in the field of robotics. More information is available on Kickstarter.
