Developed by Advanced Construction Robotics of Pittsburgh, TyBOT did 17,823 ties in two shifts across a 7,775-sq-ft area on a bridge in Wisconsin. 

Rebar demand is up nearly 9% over the first seven months of 2022 compared to the same time period in 2021.

Subcontractor estimates that use of the robot trimmed its work schedule by 25-30%.

Standing before a crowd of curious onlookers at a corner of the show floor at the World of Concrete trade show in Las Vegas, Advanced Construction Robotics president and cofounder Jeremy Searock made a sales pitch for TyBot, his company’s rebar-tying robot.

On a Pennsylvania bridge last month, a prototype robot tied more than 24,000 rebar intersections at a rate of 5.5 seconds each.
