Safety Assessment of Life-support Robots by Environment-vibration Combination Test ĜıÓ	  	  ř¤|ƈƤÀŜĹƥ
Hiroyasu IKEDA, Toshiro HOUSHI, JNIOSH
Abstract: An environment-vibration combination test for a mobile life-support robot is implemented under the worst
expected environment and road surface conditions. The test parameters change by the robot’s specifications, but thestandard temperature/humidity and road conditions are decided. The vibration applied to the robot in the environmentalchamber is reproduced from the actual running acceleration waveform. The teat result is decided passes and fails after
comparison of the change of movement and safety functions before and after the test.
Key Words: Environment-vibration Test, Safety Assessment, Life-support Robot
