Compact & Powerful Cart Towing Robot
- Enhanced QBii platform with cart attachment
- Navigates autonomously to transport goods
- Carries 50kg (boxes, bins, tools, supplies, etc.)
- Includes Raspberry Pi co-processor with camera
Description
QBii Cart is a logistics robot designed to transport goods from A to B autonomously. QBii Cart is an affordable alternative for small- to medium-size businesses and institutions who wish to automate their point-to-point delivery process.
The cart attachment allows QBii Cart to carry much more than a standard QBii, allowing a 6kg robot to tow loads up to 50kg (110 lbs)
QBii Cart is well suited for warehouses, fulfillment centers, retailers, manufacturers, machine shops, greenhouses, etc. This robot can also be used by movers, couriers, delivery companies, etc.
QBii Cart expands upon on the capabilities of the standard QBii autonomous mobile platform by adding a Raspberry Pi co-processor and a machine vision camera. QBii Cart also comes with a higher capacity 18V battery.
