Builder Assist
Builder Assist provides Surface Assist, a modular robotic platform that mounts onto standard aerial work platforms to automate repetitive construction tasks like drilling, painting, cleaning, and inspection at heights up to 20 meters. The system combines a certified 6-axis cobot arm with 3D perception and AI computing to achieve ±2 mm accuracy, and is compatible with Haulotte lifts and standard tools. A single operator can supervise multiple machines working continuously, including nights and weekends.

Product
Problem
Construction sites face chronic labor shortages, particularly for facade trades, while repetitive tasks like drilling, painting, and surface preparation remain slow, physically demanding, and dangerous. Workers are exposed to height-related risks, silica dust, and other hazardous conditions, while manual methods limit productivity and quality consistency.
Solution
Builder Assist provides Surface Assist, a modular robotic platform that mounts onto standard aerial work platforms to automate repetitive construction tasks. The system combines a certified 6-axis cobot arm with 3D perception, AI computing, and tele-operation capabilities to perform drilling, painting, cleaning, sanding, and inspection work at heights up to 20 meters. It uses a télémètre and 3D sensors for precise positioning, enabling automated execution with ±2 mm accuracy and 3D before/after scanning for quality traceability. The platform is compatible with Haulotte lifts and standard tools, allowing a single operator to supervise multiple machines working continuously, including nights and weekends.
Target Audience
Primary customers are construction companies, facade contractors, and industrial maintenance firms that perform repetitive tasks at height and seek to address labor shortages while improving productivity, safety, and quality traceability.
