Haile (robot)
Haile (pronounced Hi-lee) is a robot percussionist developed by the Georgia Institute of Technology that listens to music in real time and creates an accompanying beat. The robot was designed in 2006 by Georgia Tech's professor of musical technology, Gil Weinberg. He and one of his graduate students, Scott Driscoll, created the robot to be able to "listen like a human, () improvise like a robot" (Weinberg). Haile "listens" through a microphone mounted on the drum and analyzes the sound, separating it into beats, rhythms, pitches and several other qualities. Detecting changes in these qualities helps Haile to assume either a leading or following style of play, roles that define the robot's collaborative abilities. Haile was also the first robot to create an acoustic percussion experience rather than play music through speakers. Its anthropomorphic design, which gives it movable arms that can move in any direction, allow it to create this acoustic music.
==Goals and purpose==
Driscoll's initial goal for making Haile was to combine the use of auditory input and robotics to create a musical experience that would lead to further human–robot interaction. The final goal was a robot that could translate live music into an acoustic performance that could implement and transcend human capabilities. Haile wasn't designed to replace human musicians, but rather to accompany them with expressive playing.
These goals led to Weinberg wanting to create an acoustic musical experience. His earlier experiments failed to incorporate the visual or auditory aspects associated with acoustic music. Haile's functional drumming arms add musical cues (visually stimulating bouncing drum sticks and live, acoustic sounds) that other robot performances lack.〔 Additionally, other attempts at percussion playing robots, Weinberg saw, were limited in the variety of beats that they could produce. Haile is not only preloaded with individual beats, but is also programmed to identify pitch, rhythm, and patterns, allowing it to improvise and play different beats every time, rather than simply mimic.
