Lightweight High-Speed Anti-Collision Sensor for Drone and Robot Applications

Lightweight High-Speed Anti-Collision Sensor for Drone and Robot Applications

TeraRanger Tower Evo – Solid-state ToF LiDAR system, 4/8 detection zones, 92 grams.

TeraRanger Tower Evo is a solid-state LiDAR system. With zero moving parts, the product offers increased robustness and silent operation. At the same time, the compact and lightweight design make it ideal for fast-moving and lightweight robotic applications, both on the ground and airborne. In addition, TeraRanger Tower Evo is compatible with Pixhawk (APM) flight controllers. Choose between 4 versions with varying performance, including 4 or 8 detection zones.

Simultaneous monitoring of multiple axes

When mounted on a ground or airborne robot, the simultaneous data point acquisition of 4 or 8 axes at high speed, coupled to the natural movement of the robot (both translations and rotations), ensures the capture of features and data points around the robot, with a similar output to the laser scanners typically used in SLAM operations.
