Summary
The Spacer Robotics GRID is a compact, battery-powered wheeled robot designed to traverse rebar grids and automate repetitive steel wire tying on concrete slabs. It covers one subtask within the concrete job category: rebar tying, with rebar placement, layout, corner work, and vertical elements staying with the crew. GRID is at prototype stage with zero confirmed deployments and zero customers in the public record; all capability claims are vendor-sourced.
How it works on your site
Rebar Placement and Tying
The robot drives directly on the rebar grid and uses onboard SLAM and LiDAR navigation to locate intersections for tying. Auto-feeding wire reels handle consumable delivery during operation. The crew continues to place and position rebar, handle corners and edges, and manage vertical elements while the robot ties on horizontal grid sections.
