Rebar-tying robot set loose on big Florida highway project – Global Construction Review
A robot that can tie up to 1,100 rebar intersections an hour is being used on the $598m Gateway Expressway Project in Clearwater, Florida
The project entails adding two new, four-lane elevated tolled roadways and connections, BIM+ reports.
The brainchild of a US civil engineering company boss who struggled with labour shortages, the ‘TyBot’ uses a robotic arm rigged to a gantry crane to find rebar junctions and attach a tie before a concrete pour, saving many hours of back-breaking labour on road, bridge and other projects.
It works “continuously, day or night, rain or shine, without breaks or injury”, says its developer, Advanced Construction Robotics (ACR).
Equipped with machine vision and learning, it self-navigates its working area and requires no pre-mapping or calibration, according to ACR. It can be assembled in up to four hours by two workers and a crane operator.
