Abstract
In this study we examined the greenhouse worker's work load to test the efficiency of the developed vehicles (hand operated vehicle (HV), simple battery-powered autonomous vehicle (AV)). The subject of this study were healthy adult females who had experience in growing crops. We measured workers' heart rate, blood Pressure. rectal temperature, mean skin temperature, oxygen consumption and blood lactate level as a physiological index of work load. The results of this study are as follows : The test group using experimental vehicle showed the lower heart rate (mean
