I have built and testing my Lynxmotion A4WD1 MTS chassis and am now planning on mounting the sensors I want to use. My plan is to use the chassis for different experiments and rather than keep chopping and changing the sensors onto the supplied deck, I thought I’d build a deck for each use case. The Lynxmotion decks are pretty expensive and the default cutouts don’t make any sense to me. Instead I have bought some very cheap 3mm thick Perspex sheet off eBay, cut them to size and cut now make holes and slots only where I want them. Works well.
