The Arroyo Bridge, a 70-foot suspension bridge over a Los Angeles canyon, was collaboratively built by humans and robot arms. The structure was designed by R Scott Mitchell alongside 13 undergraduate students from the University of Southern California and features a durable crisscrossing pattern. The Arroyo Bridge was constructed through a process called collaborative robotics in which welders worked with robotic arms to attach the parts in a precise manner.
The Arroyo Bridge's construction relied on the combination of 600 steel parts in total divided into 30 sections. The accurate cutting techniques employed for the parts alongside the robotic arms replacing traditional scaffolding allow the project to significantly reduce waste. These practices proved particularly useful for sustainability purposes and also cut construction costs in half.
