|Waseda University Uses PTC Pro/ENGINEER to Develop a "Human-Symbiotic" Robot|
Cabling Capability Overcomes Difficult Challenges In The "TWENDY-ONE" Project
NEEDHAM, Mass.--(BUSINESS WIRE)--
The human-symbiotic robot called "TWENDY-ONE" is a jointly researched
and developed by
The project team used the Pro/ENGINEER Piping and Cabling Extension, which enables users to define cable properties parametrically and to find optimal routes automatically. Because more actuators and sensors are required to enhance the robot's capability, the team had to increase the number of cables. Additionally, as the team deploys higher-output actuators, thicker cables had to be introduced, making cabling design a major challenge in developing high-performance robots. "TWENDY-ONE" has a large number of sensors and actuators all over its body, which inevitably requires many cables and advanced engineering techniques. But with the advanced cabling capabilities of Pro/ENGINEER, the project team succeeded in generating accurate cable routings just by specifying certain points on the cable routes and also in updating the cable design automatically when changes were made.
"We must be very careful about the appearance and the materials used when we design the outer shell of a human-symbiotic robot because the robot should never hurt the humans or the surrounding environment on its contact," says Professor Sugano about the design requirements enabled by the Pro/ENGINEER Piping and Cabling Extension. "Also, the appearance is very important from an affinity standpoint. Exposing many cables outside the robot's body shell could create major problems, and therefore, we must place all cables inside the shell. Furthermore, cables must be compact in order not to interfere with moving parts. We could use piping or solid models to define cable models, but with the specialized cabling capabilities in Pro/ENGINEER, we can define the properties of the cables and create cable models while we see how the cables behave."
"When a cable route is updated based on a design change, the cable often sticks out of the allowable space. Pro/ENGINEER gives me that information immediately," says Yohei Uemura, a second-year mechanical engineering master's program student. "The tool also enables us to perform mechanical and cabling designs concurrently while graphically viewing the orientations and locations of the circuit boards and their relative positioning. Also, cables can be ordered accurately since accurate lengths of the cables can be obtained. We were actually able to assemble the ordered cables with little deviation, just like I viewed in the CAD tool. That was extremely impressive."
"Pro/ENGINEER Piping and Cabling Extension has been enhanced and refined
over the years to increase the ease of use and breadth of cabling design

"TWENDY-ONE" is a humanoid (height: 146.7cm, weight: 111kg) being developed for physical care and other purposes in a human-symbiotic environment, formerly introduced as WENDY (Waseda ENgineering Designed sYmbiont) in 1999. The robot is placed at the top of the field as the one that integrates hand and fingertip manipulators and other technologies at a very advanced level. The project has also attracted some attention from an educational point of view, as it gives the opportunity for students to learn the technology while nurturing a dream and gain some understanding of product development.
