Theoretical and experimental heat transfer studies are conducted for performance assessment and evaluation of various thermal insulation materials for robotic operations in this study. Nineteen different thermal insulation materials are theoretically analysed, and three of these materials (namely stone wool, fiberglass and extruded polyurethane) are tested at both low and high temperatures to obtain their thermal performance under the extreme ambient conditions. According to the experimental results obtained at 40 degrees C, the heat transfer rates between the inside and outside of the robot are obtained 120 W for stone wool, 126 W for fiberglass, and 173.9 W for extruded polyurethane. On the other hand, at -25 degrees C, the heat transfer rates are 97 W for stone wool, 107.8 W for fiberglass, and 127.8 W for extruded polyurethane, respectively. (C) 2018 Published by Elsevier Ltd.
