The Robo-Cajon is a robotic musical ’performer’ capable of real-time improvisation with a human performer. It is a wooden cajon mounted with 2 push/pull solenoids that receives input from a separate cajon mounted with contact microphones. Rhythmic data from the human performer is classified using a multi-layer perceptron and several Markov models are used for prediction and performing rhythmic patterns based on this prior classification.The Robo-Cajon demonstrates a novel approach to human-computer interaction and real-time applications for various machine learning algorithms. The Robo-Cajon was realized using Max/MSP and Arduino.
