The QBot 2 for QUARC is built on a two wheel differential drive platform with built-in encoders. It utilizes Quanser’s on-board DAQ and a wireless embedded computer to measure onboard sensors including bump, cliff, and RGBD. The DAQ also provides several I/O channels for interfacing additional digital and analog sensors. The integrated RGB camera and depth sensor are capable of capturing RGB image data and 11-bit depth data at several resolutions and frame rates. The QBot 2 operates using a host-target structure. Controllers are developed on the ground station host using QUARC for Simulink®. Real-time code is downloaded from the host to the QBot 2 embedded computer and allows users to run, modify and monitor code remotely from the host. The controllers on-board the QBot 2 are open-architecture and fully modifiable.
