Morph: Adaptive Spaceframe

prototype_1.jpg.client.x675

[William Bondin] is working on a rather interesting project, a tetrahedron morphing robot called Morphs (Mobile Reconfigurable Polyhedra). 

It is able to move by the extension of each of its telescopic edges, and as it morphs, the centre of gravity shifts, allowing it to roll over. It is far from an efficient way to move, but it is quite entertaining to watch!

The custom two-directional linear actuators were designed to ensure the weight is symmetrically distributed on each axis, and they were able get the current draw down to about 200mA during actuation, which means with a few strategically placed battery cells, it’ll be able to go wireless too. The prototype unit is controlled by a single Arduino, which sends the commands to each motor-encoder couple.

[William] is hoping to develop it into a full scale architectural prototype, and by 2015 hopes to have these interactive robotic structures rolling around public parks. The architectural end goal is to allow for buildings to respond to environmental inputs, like daylight and temperature.

Sphere morphing hexabot is a mechanical jellyfish

Once again, we’re wowed over [Zenta]‘s robotic skill. A few months ago, [Zenta] posted a video of his MorpHex hexapod spherebot that left us awed. After a few long months, more bits of MorpHex have made it onto the chassis. [Zenta] says his project isn’t done but it’s still enough to knock our socks off.

Going through the [Zenta] archives, there’s a little more to go on this time around. The MorpHex will be made up of two hemispheres, but only the bottom one will be able to walk. That’s really not that bad because [Zenta] gave the upper panels 1 degree of freedom. Just enough to scare off predators, we’re sure.

The chassis and the legs are amazing little pieces of engineering. Despite all the work [Zenta] has put into his MorpHex, there’s still work to be done. He hasn’t gotten the sphere to roll on command yet. We’ll be sure to post a video of the robot dancing to some lo-fi. Check that out after the jump.

Morphing hexapod has us drooling

morphex_morphing_hexabot

Hexapod robots seem to be a dime a dozen lately, but we think you will be hard pressed to not be wowed by [Zenta’s] latest creation. He’s built a bunch of hex and octopods before, but hasn’t tried building anything quite like this.

His MorpHex bot might look like your standard hexapod, but once it gets moving, you can see that it’s quite unique. Utilizing over 25 servos driven by a single ARC-32 controller, MorpHex moves in smooth, fluid-like motions, making it almost seem like it’s alive. The inner portion of the body can fan out, extending the overall length of the bot, though it’s more meant to allow the bot to morph into a ball and back, rather than increase its size.

In the teaser video below, you can see MorpHex in action, with its parts flowing together more like a jellyfish than any sort of land animal. While [Zenta] is continuing to work on MorpHex’s sphere-morphing capabilities, we think it would make for an awesome and creepy spiderbot!

[Thanks, weaz]
