A cast aluminium robotic sculpture.
It rolls on 3 wheels and is constantly listening for human voices. If it finds the pitch of a voice appealing the sculpture will drive to the person for a visit.
The brain uses a combination of stereoscopic sound locating hardware and a software neural network to control the piece. The neural network listens for voices of a particular pitch, while the hardware tries to locate the source of the sound.
Although the brain of this artwork is based in software and can be trained to respond to people's voices, the training process is manual and the sculpture cannot learn new behaviors on its own.
At rest the sculpture has a cover with an handle that is lifted to turn the piece on.
