How to build your own Serge in 2010

From Domestic Robots:

Serge seems to have been inspired by the Ballbot which is able to balance itself on a single spherical wheel while traveling about but what makes Serge interesting is the effortless ability to interact with humans and their home while providing a soothing human language response to commands. (...)

Here are some basic "ingredients" to create Serge in 2010:

• Robotics: Use similar technology as used by the Ballbot or Anybot's Monty
• A.I.: A mix of speech recognition/feedback system as created by Tellme Networks and Artificial Neural Networks (ANN)
• Energy Source: Fuel cell technology
• Home Navigation: A mix of laser SLAM technology as used by the Neato XV-11, visual SLAM technology as seen on Samsung Tango and NorthStar as used on WowWee's Rovio.
• Home Automation: Medina's Home Automation System.
