MorpHex MK-II in Action!

morphex mk-II

Zenta has just posted a video of his MorphHex MK-II in action! This robot is an improved version of the original MorpHex robot. This robot still can transform from 6 legged cralwer to a rolling robotic bawll. The latest version of the MorphHex has 2DOF on the upper half of the sphere, giving it much more freedom and the ability to make a variety of different shapes and patterns. We can’t help but think that the MorpHex looks like a robo-flower during some parts of the video.

The video also shows off the new and improved symmetric rolling engine and a special test at the very end. And don’t forget to check out Zenta’s MorpHex Forum Thread on the Trossen Robotics Community.

CORE Studio’s Robotic Kinetic Sculpture

Core Studio's Kinetic Sculpture

Trossen Customer CORE studio has just unveiled their newest creation: a DYNAMIXEL and Arduino / ArbotiX based kinetic sculpture.

CORE Studio is the virtual incubator for the structural engineering consulting firm Thornton Tomasetti, so it was natural that CORE Studio would build this sculpture in the Thornton Tomasetti San Francisco office.

The group started by building a quarter scale model of the final sculpture, which allowed them to test motors, sensors, code and their custom 3D printed assemblies.

Once the prototype was shown to be viable, the group began work on the final sculpture. Using their in-house MakerBot 3D printer, the CORE Studio team printed out over 350 custom parts! Over three days the group installed the 150 square foot sculpture. Each DYNAMIXEL servo can move the carbon fiber rods independently while several ArbotiX boards keep the DYNAMIXELs synchronized and working together. ArbotiX boards can be controlled via XBee wireless communication. The overall orientation of the sculpture is effected by movement in the room, which is reported to the ArbotiX boards by a series of sonar sensors.

Over the coming weeks the CORE Studio team will be fine-tuning the sculpture’s behavior to create new and interesting configurations.
