approximately 3' tall. His locomotion system consists of a
400 Series Roomba with the vacuum removed and controlled via serial
commands through its SPI interface. On top is a Yoostar
webcam consisting of a 640x480 pixel camera and dual microphones.
Inside is an Acer One netbook that has a 1.6 ghz Atom
processor, 1 gb of RAM, 160 gb of hard drive space, and built-in wifi.
Geoffrey runs custom Java software for control that uses the roombacomm
and jinput libraries. He was named "Geoffrey" by my girlfriend
due to his long neck. The bowtie is her idea too! (she
rhinestoned the tie herself). Geoffrey
has software for both on-board remote mode (using a wireless XBox360
controller), and a telepresence mode that allows both movement control
and speech synthesis. He has an autonomous "bump and turn" mode,
but it doesn't work quite well in real-world situations.
