Pennsylvania-based Advanced Construction Robotics (ACR) has unveiled its latest robot designed to handle rebar on construction sites. Named IronBOT, the system can lift, carry, and place up to 5,000-lb bundles of horizontal and longitudinal rebar.

According to ACR, the robotic system requires no pre-programming, pre-mapping, calibration, or BIM input, and instead automates rebar placement based on the user’s spacing requirements. The company also claims the system can be mobilized on a construction site within 4 to 8 hours and can operate day or night.

IronBOT’s release comes six years after Advanced Construction Robotics released TyBOT, an autonomous system that can tie together steel reinforcement bars. According to the company, a construction site that uses both IronBOT and TyBOT can reduce rebar installation times by 50%.

“We are confident the combination of TyBOT and IronBOT generates a disruptive technology, meaning the time and cost savings are so significant on a job that it will disrupt the way our industry installs reinforcing steel,” the company’s founder Stephen Muck recently commented about the suite of tools.

Last month, the system completed its first project where it was deployed for the construction of the Port St Lucie West Boulevard Bridge in Florida. During its deployment, IronBOT placed 147,000 lbs of rebar while TyBOT completed over 58,000 ties. The contractor for the project, Shelby Erectors, estimates the system cut their rebar installation time by 50%, from 14 days to 7 days.

News of IronBOT comes one week after San Francisco-based Built Robotics unveiled the world’s first fully autonomous solar piling system. Last month, meanwhile, Boston Dynamics released a new video of their humanoid robot Atlas assisting on a mock construction site.
