Background Many barns that contain livestock require some method to contain the animal waste and make it easy to clean Wood shavings are typically spread to make cleanup easier

Problem Statement Wood shavings may make cleanup easier, but it is still tedious. The shavings still need to be collected and removed.

Solution Statement Our solution consists of Autonomously driven vehicle with a vacuum source to collect the material Spiraling navigation Material collection storage area, with an auger disposal Docking station for disposal (HomeBase) For prototyping purposes, we are planning on testing and demonstrating the device in a controlled, "Lab" setting

System Overview Vacuum Pump Storage Bin Vacuum Hose Auger Out (when full & docked) Mobility Platform w/ Micro-controller and on-board power Collection Manifold Sensors A: HomeBase Receiver B: Bin Full Sensor C: Bin Empty Sensor D-E: Obstacle Sensors HomeBase Transmitter
