Looking for help: RP5 chassis and wheel encoding

ViennaMike 2011-11-13 06:30:49 6579 Views4 Replies
The RP5 chassis has one hole per drive wheel for wheel encoding. Any suggestions on the best way to make use of that? Specific parts, how to physically mount?

With one hole, is there any way to sense direction, or do I need to tie in information from the software code on which direction?

Or any specific directions on adding a different method of encoding for the RP5.

Any guidance would be appreciated.

Looks good. Thanks for sharing! Hector

2011-12-16 09:53:35 I ended up using black tape instead of paint, but it works fine. Here's a picture of one of the two home-made encoders using the Vishay TCST1202 photo interrupter. I just used hot glue to mount it. Since the encoder board sticks up above the chassis base I use standoffs to mount the plate with the Romeo controller and other electronics. ViennaMike

Thanks for posting a followup. It might help others in a similar situation. Hector

2011-12-05 20:21:42 I ended up picking up some Vishay TCST1202 transmissive optical sensors from DigiKey, and wiring them up based on the circuit in the arduino forum discussion on "Homemade wheel encoder." the circuit works, but the IR seems to go [b]through[/b] the white plastic wheel, not just through the hole! The circuit works if I put tape on the wheel, or move other objects in and out of the slot in the sensor, just not with the wheel. So I suspect I'll try painting the face of the wheel. ViennaMike
