Shared control allows a robot to use two hands working together to complete tasks

A team of researchers from the University of Wisconsin and the Naval Research Laboratory has designed and built a robotic system that allows for bimanual robot manipulation through shared control. In their paper published in the journal Science Robotics, the group explains the ideas behind their work and how well they worked in practice.

Dashing the dream of ideal 'invisibility' cloaks for stress waves

Whether Harry Potter's invisibility cloak, which perfectly steers light waves around objects to make them invisible, will ever become reality remains to be seen, but perfecting a more crucial cloak is impossible, a new study says. It would have perfectly steered stress waves in the ground, like those emanating from a blast, around objects like buildings to make them "untouchable."

Probing semiconductor crystals with a sphere of light

Tohoku University researchers have developed a technique using a hollow sphere to measure the electronic and optical properties of large semiconducting crystals. The approach, published in the journal Applied Physics Express, improves on current photoluminescence spectroscopy techniques and could lead to energy savings for mass producers, and thus consumers, of power devices.
