TeraRanger Tower is a simultaneous multi-axis scanner. It is silent and has zero moving parts. It combines up to 8 TeraRanger One sensors and the TeraRanger Hub to create a scanner for SLAM (Simultaneous Localization and Mapping) and collision avoidance. Calibrated distance data is streamed from a USB or UART port as an array of synchronized distances, in millimetres. This model comes with 4 TeraRanger One sensors.
