Researched and developed with ease of use and productivity in mind. Fully autonomous co-bot was designed for users, not engineers.

Carnegie Robotics is partnered with Nilfisk to build advanced and intuitive autonomous floor cleaning robots. The Liberty SC50 is the first product that will result from this collaboration. The SC50 is a stand-on scrubber/dryer that can be operated autonomously or manually and features two operating modes. In Copy Cat mode, the operator trains the autonomy system by cleaning a space manually. Later, the SC50 can “replay” those paths autonomously, allowing the operator to perform other activities nearby. With Fill-in mode, the operator drives the room perimeter and the SC50 automatically plans a path to clean the interior of the space.

Fully Safety Certified

Intense research and development combined with strict guidelines and a proprietary sensor and software suite, the scrubber/dryer recognizes unknown obstacles as small as a tennis ball and then automatically maneuvers around them, making the Liberty SC50 safe the only 3rd party safety certified autonomous floor cleaning system.

Drop In Autonomy Proven

‍

SC50’s autonomy is powered by Carnegie Robotics drop in autonomy kit, optimized to operate Nilfisk scrubbers. Since deployment in 2018, this system as logged over 250,000 of accident free autonomy. Its multiple sensing modalities support different perception functions (positioning, obstacle detection and avoidance, drop-off and people detection, etc.) and autonomous operation in different interior spaces with varying size, floor, wall types, and lighting conditions. CR applied a proven simultaneous, localization, and mapping (SLAM) algorithm that underpins its industry-leading GPS-denied position estimation technology.
