| Outline of Final Research Achievements |
In this research, we investigated high tensile strength synthetic fiber ropes for a robot joint driving mechanism. We measured and investigated (1)transmission efficiency when a synthetic fiber rope is wounded around a pulley, (2)strength reduction due to sharp bending, (3)strength degrade due to repetitive bending and (4)terminal fixation method. We showed that (1)transmission efficiency is very high, (2)strength reduction occurs in case of synthetic fiber ropes similar to a metal rope, (3)some material demonstrate higher repetitive endurance compared with a stainless rope, and (4)mechanical design of practical fixation method which can achieve sufficient fixation strength. We also developed an arm equipped hexapod robot for agricultural field, a long-reach multi-joint arm for decommissioning task and a sprawling-type lightweight quadruped. These robots prove the synthetic fiber rope can be used for practical robotic system.
