Troy, N.Y. — Srinivas Akella, assistant professor of
computer science at Rensselaer, was awarded a Faculty Early
Career Development (CAREER) Award from the National Science
Foundation to develop software that will eventually allow
industrial robots to do what they’ve never done before:
manipulate flexible objects.
Akella will receive $399,700 from the NSF over the next five
years to develop algorithms for the robotic manipulation,
motion planning, and design of articulated, or hinged, objects
such as cardboard packaging cartons folded from flat blanks and
“pop-up” MEMS (microelectromechanical systems) devices. The
goal is to enable simple robots to fold and assemble complex
3-D objects from two-dimensional blanks. Currently, robots are
limited to manipulating rigid objects.
“Humans use their hands and fingers and can make
accommodations for changes in the shape or size of a cardboard
box, for example,” Akella said. “A robot isn’t as sophisticated
or flexible in accommodating change. But robots have an
advantage in that they don’t get repetitive stress
injuries.”
Akella is developing algorithms to enable industrial robots to
accomplish complex manipulation tasks. By using software and
interchangeable hardware, standard assembly-line robots can be
flexible to changes in product packaging. Akella’s techniques
would reduce manufacturing costs and time required for new
products. Akella’s research may also enable batch fabrication
of 3-D pop-up MEMS devices. MEMS devices are typically
fabricated from silicon as planar elements. The challenge lies
in automating the creation of 3-D micro-optical and
microrobotic devices using microhinges to pop these elements
out of the plane. Akella is developing design and simulation
tools for the automatic manipulation and motion planning of
such devices.
In addition to involving undergraduates in this research and
developing new courses in robotics and geometric algorithms,
Akella is initiating a robotics program using Lego kits with
the Junior Museum to interest schoolchildren in science and
engineering.
