Description
QBii is an affordable, multi functional, and expandable solution for businesses, educators, and homeowners. It is operated using the QRS Control App on a mobile tablet or smartphone, which supports several advanced capabilities such as Autonomous Mode, Teleoperation Mode, Waypoint Mapping, and Path Editing.
For small to medium size commercial operations (warehouses, fulfillment centers, retailers, manufacturers, greenhouses, etc.), Qbii can help automate tasks such as carrying items weighing up to 50 lbs, towing utility carts (up to 200 lbs) with the Cart Hitch accessory, cleaning floors with the Broom Mount accessory, and inspecting surroundings with a Wi Fi enabled camera (not included).
Qbii is also a versatile platform to support STEM education and robotics research. It can be incorporated into a tech based curriculum or used as a base for research into control algorithms, sensor fusion, obstacle avoidance, etc. Moreover, it is expandable and customizable, with various interfaces (I2C ports, GPIOs, auxiliary PWM motor output, auxiliary encoder input) and an eight (8) threaded holes on the sturdy top plate for mounting customized payloads.
