NIME – HydroBot Proposal
HydroBot: Proposal For A Water-Based Musical Robot
Primary Goals:
- Create mechanical instrument that incorporates water into its mechanism
- “Essence” of water should be clearly sonified
- Mapping should be as physical as possible
- Instrument should be self-playing (robotic, though under control/programming of musician using MIDI)
- Create a tonal instrument (if percussive, then with tonal qualities)
- Create an instrument that is musically interesting
Secondary Goals:
- Generate “watery” sounds or modulate pure tones such that effect of water is clear
- Create an instrument that can be used in ensemble with other musical robots or performers
- Mapping should be visually obvious
- Technology reuse for WaterLight
Constraints:
- Must not leak
- Transportation issues (e.g. tank length)
- Should be relatively easy to fill/drain
Design Process:
- Research existing instruments (e.g. water in wineglass, water drums, WaterPhone (demo), Mocean, others?)
- Consult with others (e.g. Eric Singer/LEMUR, NIME class)
- On paper design
- Practical research
- Test/prototype/refine
Design Ideas:
- Is it possible to use water to transmit audible tones directly to air (no interleaving material) loud enough to avoid amplification?
- Experiment with metal plates and speakers excited under surface of water
- Whale songs are created using air passed through structures in the body
- Suggests to use water to modulate another another body already vibrating (metal in contact with air)

[...] Some progress on the Hydrobot front. My thinking now is that I want to move the water more, and have the movement be more visible. The goal is to make the bot be itself a performer, and that requires the audience to understand what the bot is doing and have a feeling of tension. The audience should be amazed when the bot pulls off the performance. [...]
