Build a cheap robot with no soldering, no programming, and no mechanical work. It is built on a dishwashing brush. To move forward, it will use the vibrations transmitted asymmetrically by the skew of the bristles.
I saw such a robot at the robotics festival of the Swiss Federal Institute of Technology
. I first thought it had a propeller, but soon understood it was working with vibrations.
Credits of this wonderful idea must be given to Pascal Peitrequin, explaining how to build one on http://www.expo-robots.net/rob-brosse1.html
My only and very modest contribution is to show a construction requiring yet less tools and materials.
UPDATE: the no-solder no-programming
idea came to me from the No-sew duct tape zipper pouch
, a sweet project.
UPDATE: Pascal Peitrequin told me his contribution was to use a dishwashing brush, after seeing bristle bots made with toothbrushes. (a bristlebot by evilmadscientist
- Cost: almost nothing, all should be found in a household (more or less)
- Energy: 2 x AA (or AAA) batteries
- Autonomy: hours
- Propulsion: vibrations (sonic ?)
- Actuator: small electrical motor, no reductor needed (the highest RPMs, the better)
- Speed: between snail and turtle
- Software: none. Open-loop. Not even one neuron. Can we still call it a robot ?
- Limitations: won't wash your dishes (finally, lot more neurons are required for this !)
