IOIO-SHR version 2 sneak preview

Started this weekend with the 2nd version of my IOIO-SHR (Start Here Robot). Because Santa brought me a Rover 5 chassis on christmas, this would become the chassis for it. I got the 2WD version including wheel encoders and the motor controller board.

Here are some shots from the assembly test.

The IOIO is mounted on a carrier board with 3 pin headers for all IOs. Some Jumpers are available to select the supply voltage for the IO headers, 3.3V, 5V from the IOIO or external servo voltage.

Android Open Accessory DIY DemoKit

At the Google I/O 2011 the new Android Open Accessory Development Kit (ADK) has been published. This allows to connect Accessorys to your Android phone and communicate between the Accessory and the Android via USB. The Accessory has to implement an USB Host, while the Android acts as a USB client.
