TyBot Rebar Tying Robot

by Advanced Construction Robotics

The TyBot is the world's first commercially deployed autonomous rebar tying robot, developed by Advanced Construction Robotics (ACR) in Pittsburgh, USA. Designed specifically for bridge deck construction, TyBot travels autonomously across rebar mats on a self-propelled gantry, identifying and tying rebar intersections at over 1,100 ties per hour — more than four times the rate of a skilled ironworker. This eliminates one of construction's most physically demanding and injury-prone tasks, which causes significant musculoskeletal injuries among ironworkers. TyBot has been deployed on major infrastructure projects across the United States including interstate bridge replacements and highway expansions. The robot requires no fixed infrastructure and operates entirely autonomously once placed on the rebar mat. At $400,000–$600,000, TyBot is typically purchased by large construction contractors or rented for specific projects. ACR also offers IronBot, a companion robot for rebar placing, completing the full rebar automation workflow.
