Fabrica Robotics Pte Ltd invented an autonomous tile grouting robot that operates with a single press of a button powered by Computer Vision and Robot Operating System (ROS). The robot is able to grout and clean excess grout off floor tiles, navigating a given area to automate the tile grouting process. Human intervention is only needed to move the robot from room to room, reload grout, and change water, and the robot does not need to be supervised while in operation. Real-time mapping of the rooms (including irregularly shaped corridors and the main living area) and grout an entire apartment with no need to upload any floor plan beforehand. No BIM or any prior set-up is required. The robot is small (under 60cm on each side),  reasonably lightweight (roughly 60kg), and can be easily operated by one person and able to navigate tight spaces such as corridors in smaller homes.  

Besides, using the robot means that workers do not need to bend down for grouting which may hurt their knees and back over time. Our robot also ensures high quality of grouting as it is consistently able to compress grout within gaps and not just produce a nice surface finish. This will prevent grout from falling out over time leaving behind hollow gaps in tile joints where dirt can accumulate.
We have started selling in Singapore and Australia, started trials in the US, and are looking for distributors in the UK as well. We are co-founded by Cambridge University Graduates and are funded by a Cambridge University professor, amongst various other venture capitals and construction companies.
