Actuated Responsive Truss
The Actuated Responsive Truss was completed as David Long's Master of Architecture project at the John H. Daniels Faculty of Architecture, Landscape, and Design at the University of Toronto. UTRA collaborated with David on the fabrication of the 30-actuator model that was presented in 2009. This project was published in the 2010 ICRA Workshop on Modular Robots: The State of the Art. The full publication is available here.
Trusses are used everywhere (bridges, ceilings, floors, etc.) to support load between two pillars. The amount of load that the truss can support is mainly determined by the length of the web members, or height of the truss. We have developed the first truss that can dynamically change the amount of load that it can support by lengthening and shortening its web members. The model in the video above consists of 30 linear actuators, 15 force sensors, 3 trusses and 3 microcontrollers.
This research was funded in part by The Royal Architectural Institute of Canada through the Canada Green Building Council Scholarship awarded in 2009.
