Made wheels work, need to rotate the dae file to restore that to working order.
Test pattern works wells facing straight down, try setting pose next.
I thought placing the projector on the revolutely jointed link would work correctly, but it is still glitchy when the projector is at an angle.  Next create an intermediary revolute joint and attach the projector to that.
Putting another joint in the loop didn't help much (same glitchy results), making the joint fixed as it is here causes the projector to disappear entirely.
This arrangment looks to be working, but try a few more orientations.
This orientation looks good too, try flipping to fixed again.
Fixed makes the texture disappear
Showing the pose setting not working again.
