The Walabot Starter is a small, programmable sensor tool that looks into objects using radio frequency technology that breaks through known barriers, bringing highly sophisticated sensing capabilities to your fingertips. This Walabot Starter version uses a three-antenna array to illuminate the area in front of it and sense the returning signals. The signals are produced and recorded by a VYYR2401 A3 System-on-Chip integrated circuit. They are then communicated to a host device (like your phone or computer) using a USB interface, which is implemented using a Cypress controller.
Through broadband recordings from multiple transmit/receive antenna pairs, the Walabot Starter is able to analyze and reconstruct a three-dimensional image of the environment. Analysis of sequences of images allows detecting changes in the environment. Each Starter version is capable of short-range imaging and target and breathing pattern detection, and includes a micro-B to micro-B USB cable
