Slideshow: Robots Creeping & Crawling Into New Territory
5/25/2012

The Multi-Appendage Robotic System (MARS) from Virginia Tech's Robotics & Mechanisms Laboratory looks like a giant spider with six legs instead of eight. Fabricated out of carbon fiber and aluminum, the robot's legs are spaced axi-symmetrically around its body, which lets it walk omni-directionally. Each leg uses a proximal joint with two degrees of freedom and a distal joint with one degree of freedom for added strength and rigidity. The goal is to develop a walking gait system for negotiating terrain with variations in height. The system is based on simplified biological neuron networks, arranged in subnetworks and subsystems to support the operation of another neural network: a central pattern generator (CPG) that generates gait patterns based on feedback from all supporting systems.

observation is key

Great slide show.  I wish there was video here too.  Some of these must be very elegant in action.  Thanks for the slide show.

Biomimicry in design and engineering has been around forever and proves to lead to some of the most innovative and evenually mundane products.  We all know about velcro.  I like to imagine that the wheel was invented after observing a pill bug (armadilldiidae).

Creepy, crawly with potential

I find the whole practice of biomimicky fascinating and these bug/worm robots really are a testament to how taking a page from nature can really get the innovation juices flowing. I noticed that most of these robot projects hail from universities. Makes sense to get student brain power in the mix. I'm wondering, though, how many of these are purely research efforts vs. potential for commercialized products.
