is an ethos that focuses on building robots with simple analog circuits. [NanoRobotGeek] built a great example of the form, creating a light-tracking robot that uses no batteries and no ...

Although soft-bodied robots themselves can be fairly simple, low-cost devices ... at the Netherlands' AMOLF institute, the tiny robot has been built in both two- and four-legged variants.

Here we introduce chaos control as a new strategy to generate complex behaviour of an autonomous robot ... drive 18 motors by means of a simple neural control circuit, thereby generating 11 ...

Any robot that moves needs actuators ... a short length of nitinol wire can be made into a simple muscle model that can power quick movements, using just a battery and a beginner-level paper circuit.
