TyBOT Rebar Tying Robot Evolves Beyond the Screed Rail

The Tybot rebar-tying robot from Advanced Construction Robotics is usable by more contractors as need for a screed rail is eliminated.

Advanced Construction Robotics (ACR), which offers to the market its TyBOT rebar tying robot and IronBOT rebar carrying robot, has announced a new deployment method for TyBOT, which eliminates the need for a screed rail for the robot to operate on. This requirement for a screed rail required a contractor to seek adjustments in the timeline, because the rail, which would need to be in place earlier than would typically be the case on steel-reinforced concrete construction. Tb Edgeform Bogies 01Advanced Construction Robotics

TyBOT is a gantry-mounted robot that has operated on a screed rail or porta-rail between 9.5 feet and 100 feet wide. It is powered by a Cummins Onan generator that can run continuously for 12 hours without refueling, using a 16.5 AWG poly coated single snap wire to complete up to 1,100 ties per hour. TyBOT requires a minimum bar chair height of one inch and can tie bars with intersections as small as 3-by-3 inches. It can accommodate up to #8 or #9 rebar, and while it has not been used on fiber reinforced rebar in the field, tests on this material have been successful according to the company.


A truly autonomous robot, TyBOT does not need a building information modeling (BIM) design file, or other digital information about the project. Nor has it been trained to perform its job through machine learning. Its dual camera system can see the intersections of rebar, and the robot can then execute ties either a 100% or 50% pattern on bottom and top mats. The cameras are equipped with a light ring, enabling TyBOT to work in the dark.

The robot now relies on new bogies that ride directly on the timber edge forms erected on site to support the concrete pour. Tb Edgeform Bogies 02Advanced Construction Robotics

 "At Advanced Construction Robotics, we believe that true innovation in infrastructure comes from listening to those working with our solutions in the field," ACR Founder and Executive Chairman, Stephen Muck said. "Their feedback is invaluable, influencing our product roadmaps and driving us to develop problem-solving solutions that revolutionize construction. Together, we are shaping the future of infrastructure," 

"By redesigning how TyBOT deploys on construction sites, we've created an opportunity for contractors to conduct deck operations more rapidly and efficiently than ever before," ACR President and CEO, Danielle Proctor said. "We are excited to release edge form bogies because it provides our clients a more flexible and accessible solution, increasing TyBOT's viability for a wider range of projects."
