Walabot is a programmable 3D sensor that looks around using radio frequency technology that breaks
through known barriers, bringing highly sophisticated sensing capabilities to your fingertips. The Walabot
family of products is based on VSENSE/VMAKER family of sensor modules. The VSENSE family expands the
capabilities of the previous VMAKER family, primarily for larger-area indoor coverage and higher angular
resolution, and specifically useful for smart-home applications.
The devices under VSENSE family are UWB modules to be used with an external host, or to be
incorporated together with a host in a full device, serving as the sensing product.
Features
Three-dimensional radio-frequency based sensor, based on VAYYR2401-A3 System-on-Chip for signal
generation and recording. A MIMO array of linearly-polarized broadband antennas is used to obtain highÂresolution image.
The device is operated by a stand-alone host (PC, Smartphone, or other proprietary host), through a USBÂ2 interface. The power is supplied either by the USB interface, or by an external power supply.
VSENSE models
VSENSE comes in several models. See the table below for details on the differences in the models.
