Q-Bot
Robot-applied spray-foam insulation for hard-to-reach underfloor voids
Q-Bot is a UK robotics company that sends a remote-operated crawler robot through a small access hatch into the underfloor void beneath suspended timber or concrete ground floors, 3D-scans the space, and sprays closed-cell polyurethane foam insulation onto the underside of the floor without lifting floorboards or displacing occupants. Originally an autonomous-surveying and robotics R&D platform (multiple granted and pending patents in void mapping and navigation), the company's primary commercial product today is contractor-delivered underfloor insulation retrofit for UK homeowners, landlords, local authorities, and housing associations, offered either robotically or by hand depending on access.
Why This Tool Exists
Millions of UK homes have suspended timber or concrete ground floors with no insulation, losing significant heat through the floor and causing cold draughts. Traditional retrofit means lifting floorboards or working from inside the home, which is disruptive, slow, and often impractical for occupied social housing, making floor insulation one of the most under-delivered measures in national retrofit programs.
A tracked crawler robot enters the underfloor void through a small existing or newly cut access hatch, builds a 3D map of the void with an onboard laser scanner as it moves, and then applies closed-cell spray foam to the underside of the floor in operator-guided passes, with insulation thickness monitored during spraying. The work is completed entirely from beneath the building in 1-2 days with no floorboard removal, and where robotic access is not feasible Q-Bot installs the same foam system manually.
