MASER – Mechanical Array of Sensors for Exploration Rover

The Countdown Company decided to participate to the latest’s NASA Tournament Lab-HeroX, Exploring Hell. The competition consisted of proposing a preliminary design of a system sensing obstacles in front of a Venusian Exploration Rover. The Venusian environment required the team to abandon many well known solutions since the temperature are around 450°C and the ambient pressure is 92 times the one we experience on the Earth. The proposed solution uses some mechanical arms to sense the height of rocks or depth of holes, a printed logic electrical circuit to combine the logic from the different inputs and a linear voice-coil actuator to trigger the stop button of the rover in the case of an obstacle detection.
