VSS - Vibration sampling system

NASA's Lunar Sampling System Design Challenge features the VSS - a vibration sampling system designed for efficient sample collection both on and under the lunar surface. With minimal moving parts, failure rates are minimized, and the risk of stone jamming is reduced in case of vibration. The main components include a vibrating unit and grooved feeder, which can be installed either on a lunar vehicle's Z-axis or a robotic arm in stationary landing modules. Highly deflection composite springs power linear feed movement, while the system operates through a controller or microprocessor using no more than 20W of power and weighing only 501.9 grams. By adjusting frequency and amplitude, sample types can be controlled. For larger stones or full containers, a servo-positioner arm is activated to discard large samples and fill the container with small material. The percentage of vibration is also transferred to the storage container for optimal usage. The linear feeder teeth and grooves can function as sieves or agitate surfaces. A 3D camera monitors surroundings and samples in real-time, either controlled by an Earth-based operator or functioning autonomously. An optional impact hammer, with a reciprocating direct management system and ultra-low friction chamber, can be used to collect rock surface samples while protecting the robotic arm from damage. Power consumption remains under 17W.
