How do I get the Ultrasonic Detector to work? I have followed the directions for connecting and setting up the Ultrasonic Detection board to my Revolution Roli. However, it gives no indication that it is detecting objects and the fails the collision avoidance. Regards, T. Steven Cotter, Ph.D. Engineering Management and Systems Engineering 2101I...

Ir/Serial Codes How-To

I've spent about 2 hours digging thru the community and some threads and such and can't find what I'm looking for. Does anyone have a link, tutorial or something for how to serial commands in a sequence from EZ-B? For example let's say I'm able to connect to any toy's IR port via soldered connections and know their particular IR codes that I...

Need Some Shipping Relief

I'd love to buy some jumpers from the online store here. I popped em in my cart and started the checkout. Shipping was over $21USD. For a $9 item that weighs nothing. So I can't buy them. These shipping costs prohibit me from spending my money here. Any word on boosting your Amazon presence? Your distributors don't seem to carry your full product...

Posting A New Library

What should I know before posting an EZ-B compatible library to github? Are there any obvious license gotchas the community is aware of? I have been working on a little Clojure library that speaks the EZ-B protocol. (I may eventually try to bring it up on the board directly, but I suspect the top-level APIs will remain the same.)

Check The Arms Like An Excavator

If you move the joystick slightly in one direction, The arm moves continuously slowly in the direction. If you move the joystick strongly in one direction, The arm moves continuously rapidly in one direction. For my robot I would like...

Omnibot 5402 - Belts

Saw a few posts about Omnibots here, joined the site hoping for some help. Just put a battery in my old Omnibot... has been on a shelf since the late '80s. Turned it on, went to test the tape deck and the motor turns without a tape, but with a tape it doesn't. I suspect a slipping belt issue. Anyone know what belt I need for the deck on this?...

Does anyone have an good suggestions? For some reason I am not having any luck in my search; they either don't have a mute button or are designed to work with a cellphone. Any help is...
