The idea behind this design is that the cutter will rotate around a container where the material will be stored. Also, having an exterior cutter allows for replacement cutting edges to be bolted on and if the cutter fails a new one can be put on. Another benefit of this design is the container will have very little force put on it so it can be made from an extremely light material in order to save weight. This presents multiple benefits from the current design where the material is stored in the cutter. The biggest benefit is the strain on the motor spinning the cutter. For example, on the current model the final weight of the cutter would be much heavier than the starting weight, whereas on this model the cutter would maintain the same weight allowing the cutter to maintain full power and rpms. The design is based off a rotating cutter that spins around the container and every revolution drops four cuts of material into the container. With very little modifications this cutter could have many more cutting edges added for a quicker fill time. However this whole design revolves around the motor being used to power the cutter, and the amount of cutting edges is directly based on the power of the motor spinning the cutter and the hardness of the material. The end of the cutter with the motor will have to be bolted on that way the cutter can be slid off and the material can be extracted. • Total width of scoops engaged at any given time: 175 mm• Bucket drum mass: 4.886 kg• Bucket drum diameter: 450 mm• Bucket drum length: 360 mm• Volume of regolith captured: 22.457 liters• Intended Fill: Can be up to about 90%, but considering weight this could be much lower
