1A1-C03 Development of Actuator Unit for Operation Under Extreme Environmental Conditions : Evaluation using Actual Mobile Robots

Abstract

This paper presents the evaluation results of the actuator unit for operation under extreme environmental conditions. This actuator consists of a high efficiency brushless servo motor unit equipped with torque sensor, temperature sensor, angular position sensors, and also has built-in reduction gear and is supported by large bore ball bearings. The actuator can be directly connected to the external mechanism without extra bearings. This paper presents the project concept, specifications of the final prototype and evaluation using actual mobile robots.
