That's just one thing researchers in Hod Lipson's Creative Machines
Lab envision with their latest robot prototype. It can autonomously
traverse and manipulate a 3-D truss structure, using specially designed
gears and joints to assemble and disassemble the structure as it climbs.
Lipson is an associate professor of mechanical and aerospace
engineering, and of computing and information science at Cornell
University.
Jeremy Blum '12 holds one version of a prototype robot that can autonomously climb, assemble and disassemble truss structures.
The robot's design is detailed in a paper accepted by IEEE Robotics and Automation,
to appear soon online and in print. Its co-authors include former
visiting scientist Franz Nigl, former visiting Ph.D. student Shuguang
Li, and undergraduate Jeremy Blum.
"What gets me most excited is this idea of safety," said Blum, a
student researcher working on the project. Having a robot able to climb
and reconfigure building structures, even just to deliver materials,
would be a step toward making construction zones safer for humans, he
said.
The researchers also point to space-exploration applications. Instead
of sending astronauts out on a dangerous spacewalk at the International
Space Station, a robot could be deployed to repair a damaged truss.
The robot is equipped with an onboard power system, as well as
reflectivity sensors so it can identify where it is on the structure.
This allows it to maneuver accurately without explicit commands, Blum
added.
Lipson said he envisions transforming the built environment with the
help of these kinds of technologies. Instead of making buildings out of
concrete or other non-recyclable materials, components designed
specifically for robots could be used to build or reconfigure structures
more efficiently -- for example, after an earthquake, or if an outdated
building needed to be torn down in favor of something better.
"Right now, we are very bad at recycling construction materials,"
Lipson said. "We are exploring a smarter way to allow the assembly,
disassembly and reconfiguration of structures."
The project is part of a National Science Foundation Emerging
Frontiers in Research and Innovation grant jointly awarded to Lipson at
Cornell, Daniela Rus of the Massachusetts Institute of Technology, Mark
Yim of the University of Pennsylvania, and Eric Klavins of the
University of Washington.
