See-through-wall robot

Our Chief Developer, Jonas, has equipped a robot with our D1 radar sensor, thus enabling it to see through walls. In the video below, you can see the very cool result:

How it works:

In the heart of the D1 radar sensor is a radar chip based on Ultra-Wideband (UWB) radar technology from Novelda (www.novelda.no). An UWB radar sensor sends out electromagnetic pulses and looks at the pulses that are reflected back. When an electromagnetic pulse hits the wall in the video above, a part of the pulse is reflected back to the radar and a part of it penetrates the wall and is reflected from the cabinet behind the wall.

The D1 radar sensor has several interesting functions. One of them is the ability to set a blind zone on demand. In the example above, the blind zone has been set at 1.5 meters, so that the sensor ignores everything up to 1.5 meters. Since the wall is closer than 1.5 meters it is being ignored and the distance to the cabinet behind the wall is returned by the sensor instead. The robot is programmed to always keep a distance of 2 meters away from it. Therefore, you see the robot move in accordance to the movement of the cabinet behind the wall.
