A flower pollination algorithm for efficient robot path planning
Over the past decade or so, researchers worldwide have developed increasingly advanced techniques to enable robot navigation in a variety of environments, including on land, in the air, underwater or on particularly rough terrains. To be effective, these techniques should allow robots to move around in their surroundings both safely and efficiently, saving as much energy as possible.
Researchers at the Indian Institute of Technology Kharagpur in India have recently developed a new approach to achieve efficient path planning in mobile robots. Their method, presented in a paper published in Springer Link’s Nature-Inspired Computation in Navigation and Routine Problems, is based on the use of a flower pollination algorithm (FPA), a soft computing-based tool that can identify ideal solutions to a given problem by considering a number of factors and criteria.
“Flower pollination algorithms (FPAs) have shown their potential in various engineering fields,” Atul Mishra, one of the researchers who carried out the study, told TechXplore. “In our study, we used the algorithm to solve the problem of path planning for mobile robots. Our prime objective was to plan, in the least time possible, the most optimal path in terms of minimum path length and energy consumption, with maximum safety.”
They’ve Contained the Coronavirus. Here’s How
But lockdowns and forced quarantines on this scale or the nature of some methods — like the collection of mobile phone location data and facial recognition technology to track people’s movements — cannot readily be replicated in other countries, especially democratic ones with institutional protections for individual rights.
And so Singapore, Taiwan and Hong Kong might be more instructive examples. All three places were especially vulnerable to the spread of the infection because of close links with mainland China — especially in early January, as they were prime destinations for Chinese travelers during the upcoming Lunar New Year holiday. And yet, after all three experienced outbreaks of their own, the situation seems to have stabilized.
As of midday Friday, Singapore had 187 cases confirmed and no deaths (for a total population of about 5.7 million), Taiwan had 50 confirmed cases including 1 death (for a total population of about 23.6 million) and Hong Kong had 131 confirmed cases including 4 deaths (for a total population of about 7.5 million).
If this era of automation mirrors the past, we’re in trouble
“In the case of the Industrial Revolution, people’s lives didn’t improve for seven decades,” Frey says. “That’s two generations. I think we need to be very concerned about some of these short-term effects on people.”
Frey says for seven decades wages were stagnant, food consumption decreased and “people’s living standards deteriorated.” The economy was doing quite well, but most of the workers weren’t seeing the benefits of that economy.
“Because people’s living standards deteriorated, people rioted against mechanized factories. The Luddites are often portrayed as these irrational enemies of progress, and to some extent, that’s right if you take a very long term view,””
The case against the flawed argument that automation won’t be so bad.
Google releases quantum computing library
Google announced Monday that it is making available an open-source library for quantum machine-learning applications.
TensorFlow Quantum, a free library of applications, is an add-on to the widely-used TensorFlow toolkit, which has helped to bring the world of machine learning to developers across the globe.
“We hope this framework provides the necessary tools for the quantum computing and machine learning research communities to explore models of both natural and artificial quantum systems, and ultimately discover new quantum algorithms which could potentially yield a quantum advantage,” a report posted by members of Google’s X unit on the AI Blog states.
Chinese Robot Is Designed to Help Doctors Fight Coronavirus
Chinese researchers have developed a robot designed to help doctors treat the new coronavirus and other highly contagious diseases.
The machine has a long robotic arm attached to a base with wheels. It can perform some of the same medical examination tasks as doctors. For example, the device can perform ultrasounds, collect fluid samples from a person’s mouth and listen to sounds made by a patient’s organs.
Cameras record the robot’s activities, which are controlled remotely so doctors can avoid coming in close contact with infected patients. Doctors and other medical workers can operate the machine from a nearby room, or from much farther away.
New Antenna Will Boost UAV Communication with Satellites
A group of Chinese researchers has developed a compact, sabre-like antenna for unmanned aerial vehicles (UAVs) that can switch between two radiation patterns for better communication coverage. They describe their work in a study published 26 February in IEEE Transactions on Antennas and Propagation.
For UAVs cruising at high speeds, it’s desirable to have small, aerodynamic antennas that limit drag but can still yield sufficient bandwidth and coverage. Zhijun Zhang, a researcher at Tsinghua University, notes that sabre-shaped antennas are beneficial in the sense that they are very aerodynamic—but there is a major limitation that comes with this design.
“Conventional sabre-like antennas generate a donut-shape radiation pattern, which provides an omnidirectional coverage and is ideal for air-to-ground communication. However, a donut-shape pattern has a null at its zenith,” Zhang explains.
