Passive-Dynamic models

Peter writes – The devices shown here were created to explore aspects of regular, step-wise locomotion where the only energy input required is gravity. The first models were attempts to find a non-collision version of the “Wilson Walkie” type of ramp walker. These maintain constant surface contact and move with a rolling, non-scrubbing motion.

Matt Trossen at RoboDev

Matt Trossen’s talk from the 2007 RoboDevelopment conference is on YouTube (in ten parts). He does the typical techno-timeline leading up to robotics, posits where robotics can go, the impediments, next steps, need for standards, the usual drill, but well laid out. I like the way he starts out: When I look out into the […]

Hamster-powered night light

Here’s a little howto on building a low-RPM generator from scratch. I assume that not all of you have extra hamsters lying around to power your night lights, but a similar design could be used for creating a small generator for wind or other energy sources. Though it’s hard for the hamster to make higher […]
