An ultrasonic sensor detects its presence and starts to read the colors of the cube faces using a light sensor. The robot turns and tilts the cube in order to read all the faces of the cube.

Purdue’s aspiring engineers set a new Guinness World Record.

Sonair’s 3D ultrasonic sensor uses acoustic detection and ranging (ADAR) to enable 360° obstacle detection up to 5 meters. Each ADAR sensor offers a 180×180° field of view, allowing autonomous mobile ...

On that note, we've recently stumbled across Cubli, a little cube-shaped robot made by Gajan Mohanarajah, Ph.D. candidate and research ... reduces vibrations and sensor noise." ...

Sonair is a 3D ultrasonic obstacle detection sensor that provides a “safety shield” around a robot. The new sensor operates by emitting a burst of ultrasound and then analyzing the signals ...

This method is more reactive to external disturbances and reduces vibrations and sensor noise." The resulting robot ... the cube, effectively rolling along. It's really cool stuff, and we'd ...
