Machines that do not just play notes
they listen, respond, and groove.
Jazz is built on interaction. The drummer provides the rhythm for the entire band. The bassist outlines the chords while providing solid quarter notes. The pianist adds a finishing touch to the roots the bassist provides. The horns and brass make phrases off of the rhythm section. Everyone collaborates and depends on the rest of the band.
Most music robots are either pre-programmed machines or mechanical instruments that play fixed tracks. Jazzbot can make its own, new music, and work with real people
Jazz is a strong testbed for musical robotics because it demands real-time:
The project began with the idea of a robotic jazz band: a robot drummer, a robot pianist, a human bassist, and a human trumpeter. The goal is not simply to automate music, but to create robots that can eventually listen and respond like bandmates.
The project architecture was defined around Jetson Orin as the high-level brain. Jetson handles timing, musical logic, planning, and future AI listening. Lower-level controllers handle real-time actuation.
Two A1/OpenArm-style 7-DOF arms with two ORCA hands. The main risk is not whether the parts can connect — it's whether ORCA fingers can press piano keys cleanly, repeatedly, and with useful timing.
The drummer is much easier than the pianist because it mainly requires timed strikes instead of precise finger placement. Fixed actuator modules for all main voices became the recommended first milestone.
The drummer can be made more human-like without becoming a full humanoid robot. A hybrid: human-like torso behind the kit, two visible robotic arms, fixed actuator modules for reliability, one movable accent arm.
At 50 hours/week, the drummer can reach a jazz demo in 3 weeks. A limited two-arm pianist prototype in three months is possible, but aggressive. Full virtuosity is not a three-month target.
JazzBot is an experimental robotics and music project exploring live robot-human jazz performance. Collaborators welcome.
