Today we worked more on our prototypes.
Here is the working version of our tote puller. This mechanism will be used to retrieve the totes from their starting configuration and move them around. We still have to perfect the tension and position of the surgical tubing.
Our drive train has been modified to be an H-drive consisting of two rear wheels and a large omni wheel on the front. This could potentially allow us to strafe sideways and at angles to align the totes more easily.
