Student-made device sends obstacle warnings to mechanical bug’s brain
Can a robot learn to navigate like a cockroach? To help researchers find out if a mechanical device can mimic the pesky insects behavior, a Johns Hopkins engineering student has built a flexible, sensor-laden antenna. Like a cockroachs own wriggly appendage, the artificial antenna sends signals to a wheeled robots electronic brain, enabling the machine to scurry along walls, turn corners and avoid obstacles.
The work is important because most robotic vehicles that are sent into dangerous locations rely on artificial vision or sonar systems to find a safe path. But robotic eyes dont operate well in low light, and sonar systems can be confused by polished surfaces. As an alternative, Noah J. Cowan, an assistant professor of mechanical engineering at Johns Hopkins, is turning to the sense of touch, drawing inspiration from bugs that move quite skillfully through dark rooms with varied surfaces.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
