Due to the extreme environmental conditions on Mars, humans will be exposed to thermal discomfort producing an imbalance of homeostasis that can affect the general health and physical performance of astronauts. Therefore, Bioastronautics and Space Mechatronics Research Group conducted a study from 2019 to 2021, resulting in the proposed project named T-EVA which is a Medical Robot, defined as a wearable embedded mechatronic system for continuous temperature monitoring of the upper limbs especially during extravehicular activities at Mars Analog. This research presents the version 2.0 of the device, where the analysis is focused on the telecommunications technologies and protocols to connect the astronaut to the Command Center, and also the improvements of the electrical-electronics design. It has been chosen in 2020 by The Mars Society to evaluate its functionality and to develop the technical-clinical validation tests at The Mars Desert Research Station in Utah, USA, in order to be part of Team Peru VI in 2022. Also, it was chosen among the 10 best projects for the Mars University Symposium 2021.
