Hardware at Google IO

So my last post was about how, from looking at the Sessions list for Google IO 2012,  it looked as though Google had abandoned the hardware they presented at last year’s Google I/O. Now that IO 2012 is going on, we have some more information about what they’ve been doing.

  • Project Tungsten has turned into the Nexus Q, a music streaming device that Google is actually manufacturing (and manufacturing in the U.S., it seems)
  • Google launched their own tablet, the Nexus 7

More interestingly for me (and other robotics enthusiasts), is the remarkably quiet news that there’s a new ADK in town.

The ADK 2012 is still based on Arduino, but I haven’t found much info on it yet. The only picture I’ve seen is over at the Arduino blog. Apparently they distributed “a limited number” of them at IO, but it  wasn’t mentioned in the Keynote, like the original ADK was (now called ADK 2011).

Lack of hardware focus at Google IO 2012?

The schedule for Google IO 2012 has been released, and it doesn’t look like there are any sessions dedicated to hardware. This is kind of surprising, considering how much attention was paid to HW last year. At Google IO 2011 a good 15 minutes of the Day 1 Keynote was spent discussing the open accessory API, plus Android @ Home and Project Tungsten. There were technical sessions dedicated to the Open Accessory API, Cloud Robotics, and NFC. And remember the giant “labyrinth” game set up to demonstrate on a large scale? Google hasn’t done a whole lot since then to promote these different projects. I’m not sure if they’ve pushed Android@Home or Tungsten at all, although I guess there are some rumors about a multimedia device going around.

Even beyond the lack of continued support for things they announced last year, there have also been a few developments since then that should be worthy of a few sessions, right?

  • Google has an autonomous vehicle, and even a license to operate on the road! But no sessions to discuss the self-driving car project?
  • Google is acquiring Motorola Mobility, one of the premier mobile device makers. Not a whole lot has been said about this, but I guess they’ve been waiting for approval (and I see that just today China has approved the deal)
  • Google is now selling the Galaxy Nexus device direct to consumers, which is a pretty big shift in hardware delivery strategy
Maybe it’s just a little early to tell what they’re up to. Maybe more will be made in the Keynote presentations instead of the technical breakout sessions. But if they’ve actually made some progress on these projects (for instance, if the rumors are true and Android@Home will be supported in Jelly Bean) it would probably be good to start training developers on how to actually implement these things…



Android App for the Zeemote bluetooth controller

A few weeks ago I attended the Android developer conference, AnDevCon in San Francisco. One of the registration giveaways was this bluetooth remote control from Zeemote. It’s very small, and right now only a few games support it. I wanted to experiment with it a little bit, to see what else it might be useful for, and wanted to write a quick demo program. Since I learned about Fragments at the conference, I though I’d use this as an excuse to include them in my project.

One Fragment will display indicators for the 4 buttons on the controller. The other will represent the position of the joystick.

Zeemote does offer an SDK for interfacing with the device, and some code samples to help get started. You have to register by giving them your email address, then you can download the SDK.

Now, here’s my walkthrough for creating this demo app, using Eclipse.

Opening up the Google ADK

The Google ADK Board

I thought I’d provide some details on what’s provided with the Google ADK board, and start sharing some of my experiments with it (more to come!)

First, the base board itself is an Arduino Mega 2560 with USB Host shield, pretty much identical to the official Arduino ADK board.

ADK Achieved!

After finally learning the unfortunate news that my Acer Iconia Tab A500 did not support USB Accessory Mode and realizing that I wouldn’t be able to use my Google ADK or do any Android Open Accessory development, I decided to return the tablet and purchase a Motorola Xoom instead.

Well, the tablet arrived, and I eagerly plugged it in to the ADK, and it worked right away, just like it should.

In addition to actually supporting Accessory mode, it’s nice to see that Motorola actively supports a development community at MOTODEV.

Now that I have a working system, it’s time to get started with accessory development. In addition to the ADK, I also have a VNC2 and I just got an IOIO from SparkFun.
