The subjects of this paper are a requirement clarification for a robotic structural matrials and a proposal of the new concept by the comparison with the conventional mechanical structural materials. Take into account a evaluation method for the flexibility on the bicycle structure, the evaluation method of robotic structural matrials properties is considered. Focusing on carbon nanotubes have excellent mechanical and electrical characteristics of both, the CNT/PVDF composite is tried to fabricate, and evaluated the characteristics of the sensor. The sensor characteristics of CNT/PVDF composite is used to change electrical resistance by the strain to occur from external load. The fabricated CNT/PVDF composite is compared some mechanical properties with the typical conventional mechanical structure. The possibility of CNT/PVDF composite is considered for a robotic structural materials. CNT/PVDF composite elastic modulus for 22.3 vol% CNT was the highest. The degree of elasticity has improved by about 40 % compared with PVDF. As a result of the measurement the electrical resistance by using composites with 5 wt% CNT, the rise and fall of the sensor signal was confirmed by the strain change.
