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.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
