The i-Sobot humanoid robot is still the world's smallest humanoid robot in production according to the Guinness Book of World Records. i-Sobot already danced onto the scene in 2007. A year ago Amazon sold the little robot for $300. Now gadget shop Hammacher and Schlemmer is selling the i-Sobot for only $99.99.

This a pretty low price for the high tech toy you are getting with the i-Sobot. Additionally Amazon still charges $179.99 for the i-Sobot robot. The i-Sobot robot has 180 preprogrammed individual movements, responds to verbal commands, and performs up to 240 movements in sequence, allowing you to design countless routines, such as programming the device to say "hello," introduce himself, play an air guitar, bow to his audience, and say "good-night."
Using the included action chart as a guide, simply enter the alphanumeric codes into the remote control and the little droid reacts in earnest with acrobatics, verbal phrases, and greetings, or you can control the robot's movements manually using the dual joysticks and trigger buttons on the remote.

In voice recognition mode, the robot moves in response to 10 verbal prompts such as "Go forward" or "Back up," and acknowledges questions like "How are you?" with appropriate retorts.
The robot is controlled by 17 customized servomotors with built-in clutches; a gyro-sensor ensures optimal balance and the 17 points of articulation in the neck, arms, hands, legs, and feet allow human-like movement.
