TeraRanger One


TeraRanger One is a lightweight, high-performance distance measurement sensor based on infrared Time-of-Flight (ToF) technology.

It is much faster than ultrasound and far smaller and lighter than laser-based systems. Its small size, high performance and low power consumption make it ideal for modern robotic applications, drone operations and automation, whilst its cost-effectiveness also makes it suitable for high volume usage as well as powerful research and DIY applications.

For crosstalk avoidance in multiple robot environments two versions of the sensor are available, type A and type B, which can operate simultaneously without affecting each other’s reading. Sensors A and B performance are very similar. We prefer A for indoor environments and B for outdoor as the latter is more stable in direct sunlight.

Davide Scaramuzza on TeraRanger One quoteProf. Davide Scaramuzza, Director of the Robotics and Perception Group, University of Zurich, Switzerland

“Teraranger One is a revolutionary sensor for flying robotics; its fast update rate, long range, and accuracy are terrific to ensure safety and inspection operations by flying robots.”


The European Organisation for Nuclear Research, CERN, independently tested the TeraRanger One and compared it with alternative range-finding solutions. In their conclusion they write:

[the TeraRanger One is] …A novel distance ranging device for autonomous navigation, its lightweight makes it suitable for all kinds of robotic platforms, even in payload-limited conditions (flying devices such as drones, wheeled robot, robotic arms). Its good accuracy combined with its high speed allows using it for autonomous system position definition and navigation.
