Here is a simple CAD of our West Coast Chassis with the drop down e-plates cfair was talking about. We have two e-plates on this robot, and both are able to be dropped. However, in this CAD I only dropped down one to show what one e-plate would look like when it is not dropped.
wyrzykowskij1 also asked what the dimensions of this robot are. Currently we are at 29.5 inches x 26.25 inches.
