Moving 3-D Printer

While 3D printers are able to print virtually anything, the size of what’s able to be printed is limited by how big the printer is. Well, that isn’t a problem anymore!

Researchers from Pontificia Universidade Católica do Rio de Janiero have made a 3D printer on wheels. With 4 omni-directional wheels and an extruder that points out of its body, the bot can stuff as large as your table/surface can allow.

It’s controlled by an Arduino and could be wirelessly controlled from a computer. Take a look.

Robot Lumberjack

With conspiracy theorists teeming with excitement over Google’s potential Skynet plot (buying Schaft, Boston Dynamics, self driving cars…what gives?), roboticists Yasuhiko Ishigure, Katsuyuki Hirai, and Haruhisa Kawasaki, are adding to the fray, with this  lumberjack bot.

This chainsaw bot is not only capable of climbing up and down trees, but can also dismember them without human interaction. The robot can spiral its way up tree trunks ranging from 2.3 to 9.8 inches in diameter, and easily lops of limbs up to about two inches in diameter without a second thought…actually, without a thought at all.

Behold, the ”Pruning Robot With a Power-Saving Chainsaw Drive.”

It doesn’t matter how much smooth jazz you play as it tears up the tree, slicing off branches, it’s still a deadly machine. While the machine could definitely reduce the need for human labor, the fact that it can climb and slice limbs seems like a horror movie waiting to happen. Imagine what this thing could do if it latched onto your leg. Eesh.

MIT’s new exoskeleton arms

Need a hand? Two? Look no further!

Thanks to a team of researchers at MIT’s d’Arbeloff Laboratory, a set of robotic arms have been developed which can be mounted on your shoulders or waist. Now…where have I seen that before?

Meant to augment actual arms, these robotic arms instead base their movements off of the movements of their wearer’s entire body, measuring acceleration and orientation to predict what they should be doing. By detecting and anticipating what your own arms are trying to do by using a pair of wrist-mounted sensors, the robotic arms will position themselves to assist the wearer.

The MIT researchers are also working on a separate set of arms, pictured above, that will help with building planes. It attaches to the waist, and it’s meant to be used to hold objects or brace the someone while they’re working. And irritate Spidermen.

Indestructible robot crawls through fire

Try to burn it, run it over, or freeze it, and it just keeps on crawling. Developed by Michael Tolly of Harvard University and his team, the pink X-shaped robot is completely soft, with no rigid skeleton.

At 65 centimeters long, this robot has a battery capable of running for 2 hours on a single charge, and an air compressor system that drives its pneumatic motion. With a flexible body that can navigate through small spaces, and designed to be used in harsh terrain, this robot is ideal for search-and-rescue missions. It can work in temperatures reaching -9 °C, and can withstand fire for 20 seconds, get run over by a car, and resist water and acids.

Robotic hand performs underwater tasks

To touch, or not to touch. For this robot, the answer is the former, always the former. A hand with three digits, the robot designed by Achint Aggarwal and his team at the German Research Center for Artificial Intelligence in Bremen lives to examine the depths of the ocean by touch.

With underwater visibility hampered by impurities and/or sediments in the water, objects and extremely difficult to locate and manipulate. To look past the waters’ impurities, Aggarwal’s team made the hand, which could be attached to an undersea vehicle. Built-in sensors in the hand can track changes in texture, movement, and pressures as it moves around. It can then use that information to make a map of the object and make a guess about what it might be, with 90% accuracy.
