Yesterday we were between several ideas before settling on a walkable dog treadmill. We started with a solid idea so it hasn't changed much since then. Although, we received feedback that  making a remote controlled one of these would be too difficult and time consuming to do within the two weeks we have so we're just making it so one can pull it. We decided to make that decision because of the time and skill constraints. After figuring all this out we started on a rough cardboard prototype of our project with a semi working treadmill on top of it eith a duct tape belt.
