Shanghai Jiao Tong University
Shanghai Jiao Tong University researchers including Dr. Gao Feng, Director of
the Chinese National Laboratory of Mechanical System and Vibration at SJTU
and Dr. Yang Pan, Postdoctoral Research Fellow at SJTU, have designed the
Octopus III six-legged robot for moving, searching, detecting, repairing and
rescuing in extreme environments such as nuclear radiation, fires, and underwater.
The six-legged Octopus III robot takes advantage of the unusual capabilities
of legged robots such as traversing uneven terrain, overcoming obstacles,
performing vertical climbs, and righting themselves after turning over.
The SJTU researchers tested the prototype under a wide range of conditions such as turning valves and switches and carrying loads of up to 500 kilograms in order to evaluate its fitness for proposed missions. The physical experiments showed that the performance of the prototype closely matched the Adams predictions. “If we had not used Adams to optimize the design prior to building the prototype, we would probably have needed five additional prototypes at a cost of $100,000 each to get the design right,” Pan said. “With Adams, the first prototype worked exactly as intended so we did not have to make a single change.”
