Robot Platform

I spent a little time coming up with a very simple robot platform. Attached are the schematic and design.

The circuit contains two photosensors for speed sensing, and two distance (front/back) sensors.

My intention is to make a custom PCB (placement marked in the rendering).

I love some feedback.

I'd suggest making the pcb your chassis, as done by a couple of popular robot kits out there.

Also, don't forget a third wheel/support, I can't see any in the cad pic you attached but your bot will drag one of its ends on the floor otherwise.
