They are using the audio jack to send command data to the robot base. Notice how the iphone is not connected through a dock or 30-pin connector. Very clever indeed!
Making a "real" iphone accessory through the 30-pin connector is simply not possible for hobbyists/small outfits. This also makes their communication interface with the robot somewhat portable. I like :D
- gregsadetsky 15y agoThe audio port is definitely the right way to interface cheaply (and across different mobile phones). If anyone's interested, there _is_ now a way to interface RS-232 devices from an iPhone using an Apple-approved cable: http://www.makershed.com/ProductDetails.asp?ProductCode=MSRP02 http://www.makershed.com/ProductDetails.asp?ProductCode=MSRP... From what I've heard, negotiations with Apple took a lot of time and were quite "complex". Also, the cable unfortunately costs 80$ (because of the custom, "secret" DRM chip enabling the interface). Which goes to prove that the audio jack goes a long way!
