Android stretches its legs... errr wheels... with help from 20% time at Google
Android stretches its legs... errr wheels... with help from 20% time at Google: "
By Ryan Hickman, 20% Robotics Task Force

Today we announced a fun 20% robotics project that resulted in three ways you can play with your iRobot Create®, LEGO® MINDSTORMS®, or VEX Pro® through the cloud. We did this by enhancing App Inventor for Android, contributing to the open source Cellbots Java app, and beefing up the Cellbots Python libraries. Together these apps provide new connectivity between robots, Android, the cloud, and your browser.
You can start empowering your Android phone with robot mobility by picking the solution below that matches your skill level and programming style:
- App Inventor for Android
This is an entirely cloud based programming environment where you drag and drop elements into a project right within your browser. The latest features for robots include a low level Bluetooth client for connecting with many serial-enabled robots, and tight integration with LEGO MINDSTORMS. There are seven LEGO components in all, with NxtDrive and NxtDirectCommands used for driving and basic control while NxtColorSensor, NxtLightSensor, NxtSoundSensor, NxtTouchSensor, and NxtUltrasonicSensor are used for sensors.
Also be sure to try out the social components to connect with Twitter, and TinyWebDB for hooking up to AppEngine. All of these can be used together to make your phone a powerful robot brain.
- Cellbots for Android
We wanted to offer a flexible application that could drive multiple platforms and support different control modes. To do this we created the Cellbots Java application which currently supports four robot platforms and allows additional robot types and UI control schemes to be added using the standard Android SDK. It is entirely open source and available for free in the Android Market so you can try it out right away.
With it you can use the phone as a remote control with D-Pad, joystick, accelerometer, or voice control inputs. Then try mounting your phone to the robot in brain mode where you can stream video back to a web browser and make the robot speak using Android’s native text-to-speech. For those of you with two Android phones, we support remote-to-brain mode where you can ask the robot for its compass heading or change the persona on screen.
 
- Cellbots Python library
The 20% team got together to create a more modularized version of the popular Cellbots project, which is all open source code. The goal for the Python library is to allow developers an easy way to demonstrate the features on Android phones suitable for robots. There are commands to make it speak, listen, record audio, take pictures, get a geolocation, and of course provide the I/O to the bot.
The Python code is the most flexible in terms of connectivity with support for Google Talk chat over XMPP, HTTP through a relay or direct connection, telnet, and voice input. To use it you just need to install the Scripting Layer 4 Android and enable the Python interpreter. Then copy over the Python and config files to the SD card and script away.
We hope this gives developers, hobbyists, and students a head start in connecting the next generation of cloud apps to the world of robotics. Be sure to push your mobile phone’s processor to its limits and share the results with the Cellbots Google Group. Try using Willow Garage’s OpenCV for Android or the new Gingerbread APIs for gyroscopes, enhanced OpenGL graphics, and multiple cameras!

BigQuery, meet Google Spreadsheets
BigQuery, meet Google Spreadsheets: "
"
Since announcing BigQuery at Google IO last May, we’ve been very excited by the response and feedback we’ve received from the developer community, enterprises and academia. The one consistent request we heard from everyone is the ability to interactively analyze large volumes of data without having to worry about provisioning, maintaining and scaling infrastructure.
Today, we would like to announce the integration of BigQuery with Google Apps Script and Google Spreadsheets, a feature we first demoed at Google IO. With this integration users now have the power to query multi-billion row tables, visualize the results and share them with others. Below you can see a simple script that queries a sample dataset and plots the results. A simple tutorial is available here with more to come soon.
We’ve seen a big uptake of the APIs (released in October) which let you create, populate and delete tables in BigQuery. Users have been loading more and more data in BigQuery. For instance the current M-Lab dataset in BigQuery stands at 240B rows!
The details of BigQuery and new features are available on the BigQuery website. We are gradually adding more developers during this free preview period. Please sign up for an invitation, and let us know about the creative and valuable ways you’re using BigQuery.

Google URL Shortener gets an API
Google URL Shortener gets an API: "

When we launched Google’s URL shortener externally back in September, there was no accompanying API to allow people to integrate goo.gl into their applications and web pages. However, we said that we were working on one, and today we're happy to announce that we’ve launched the goo.gl API in Google Code Labs. The documentation can be found on the Google Code site, with example code in the Getting Started section.
With this API, developers are able to programmatically access all of the fast, sleek goo.gl goodness that we currently provide via the web interface. You can shorten and expand URLs using the API, as well as fetch your history and analytics. You could use these features for a wide variety of applications, enabling behaviors ranging from auto-shortening within Twitter or Google Buzz clients to running regular jobs that monitor your usage statistics and traffic patterns. You can check out the Google APIs console to get started.
We’re very excited to be able to offer you this API to access one of the fastest URL shorteners out there. We’re continuing to work on several usability improvements and to make our auto-detection of spammy or malicious content even more robust. We hope that with the new API, you’ll find goo.gl to be even more useful in your future shortening endeavors! If you’re an application developer, check out the goo.gl API documentation and see how it looks.
