On the second day of Google I/O 2011 , Ryan Hickman, Ken Conley, Brian Gerkey, and I gave a tech talk about cloud robotics. You can watch the talk now on YouTube . We'll also be at Maker Faire next week! There will be more robots and plenty more open source goodness. During the talk, we announced the release of rosjava , the first pure Java implementation of ROS . One exciting aspect of rosjava is Android compatibility. You can now integrate Android devices with your ROS-enabled robots and write apps for them. In addition, with the newly announced Open Accessory API and ADK , you can start controlling actuators or reading external sensors directly from Android devices. Android devices offer tons of sensor and user interface possibilities to robots. Beyond that, they also offer robots a link to the cloud. Cloud robotics is about making robots universally accessible and useful. Robotics is full of hard problems that make intelligent interaction problematic. Robotics res...

Here's a tiny bash function I wrote to do it with mencoder ( sudo apt-get install mencoder ): function combineavis() { read -p "Combined AVI name: " -e output mencoder "$@" -o "$output" -ovc copy -oac copy } I also found this page (which has quite a few handy snippets about lots of various Linux tasks). It recommends using avimerge -o "$output" -i "$@" instead.
