Modular Climbing Robot Splits into Multiple Explorer Bots

Researchers from the Robotics Research Centre at the International Institute of Technology – Hyderabad (IIIT-H), have developed a stair and obstacle climbing robot that can disassemble itself into smaller robots, and then reassemble back into one device. As a composite system, the Detachable Compliant Modular Robot (DCMR) can climb steep obstacles and staircases, and explore uneven terrain. When it detaches into multiple robots, it can explore cramped spaces, traverse flat terrain, and behave as a Multi Agent System (MAS).

Actuated Smartwatch Moves in Five Directions

In an effort to make digital smartwatches more convenient for users, researchers at Dartmouth College and the University of Waterloo have produced a prototype watch face named Cito that moves in five different directions. With the ability to rotate, hinge, translate, rise, and orbit, the model improves functionality and addresses some of the limitations of today’s fixed-face watches.

Mechanical Actuators Bend as They “Breathe”

Extreme temperatures can severely strain a mechanical component because its material may have trouble enduring the heat without degrading. To address the problem, researchers at MIT developed a new material that expands and contracts as it lets oxygen in and out. The result is a new way to make actuators that could be used in extremely hot environments.

3D-Printed Soft Robot ‘Walks’ on Any Terrain

Traditional robots often feature isolated mechanical joints. These discrete components limit a rover’s ability to traverse sand, stone, and other challenging environments.

A team at the University of California San Diego has demonstrated a more flexible option: a soft robot that lifts its legs over obstacles and operates on a variety of terrains. The 3D-printed quadrupedal technology may someday support search-and-rescue missions requiring intelligent navigation capabilities.

Coming to a Lab Bench Near You: Femtosecond X-Ray Spectroscopy

The ephemeral electron movements in a transient state of a reaction important in biochemical and optoelectronic processes have been captured and, for the first time, directly characterized using ultrafast X-ray spectroscopy at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). Like many rearrangements of molecular structures, the ring-opening reactions in this study occur on timescales of hundreds of femtoseconds (1 femtosecond equals a millionth of a billionth of a second). The researchers were able to collect snapshots of the electronic structure during the reaction by using femtosecond pulses of X-ray light on a tabletop apparatus.

Engineers Invent Method to Control Light Propagation in Waveguides

A team of Columbia Engineering researchers, led by Applied Physics Assistant Professor Nanfang Yu, has invented a method to control light propagating in confined pathways, or waveguides, with high efficiency by using nano-antennas. To demonstrate this technique, they built photonic integrated devices that not only had record-small footprints but were also able to maintain optimal performance over an unprecedented broad wavelength range.
