Description

Dr. Messmore
“Dr. Messmore, MD” ~ automaton
“Mad Scientist” – Servo controlled mechanism

YEAR: 2003
SIZE: 24 x 12 x 12 inches
MEDIUM: Mixed media
MATERIALS: Servo motors, electronics, brass, wood. Resin, epoxy clay, wool crepe hair, glass eyes, fabrics.
MOVEMENT: “The Dr.” moves head side-to-side observing his audience, slowly pushing/pulling the lever of the Hypno-machine. Lights begin pulsating while his right hand simultaneously turns the hand crank causing the Hypnodisc to spin as “The Dr.” attempts to hypnotize unwitting victims. OOAK 1/1. Video available: C+M Videos see “The Dr.” in action.

Mechanism

Movement is programmed and recorded using Visual Servo Automation (VSA) servo control program. The vertical lines trigger the start/stop time creating the servo movement: head forward/ back/side to side, hand crank lever push/pull activates pulsating lights, and spins Hypnodisc.  More about servo programs, see BLOG POST: Electronic Automata

For the last few years, I have been experimenting with servo electronics to move figurative sculptures in a lifelike manner. I have been using a computer program called Visual Servo Automation (VSA), which allows me to define a wide range of motion and duration for each servo movement, then save each motion in the computer and replay it any number of times. The servomotors, programmed at different forward and reverse speeds, alone or in unison, create the effect of an animatronic figure. By having the ability to program the automaton’s movements, I can work out the motions and finesse the mechanical design before machining the parts, which saves a considerable amount of time. Moreover, I am able to change the movements of the prototype without completely redesigning the mechanism, giving creative freedom without technical limitations.
