అఖిలేశ్ యాదవ్ను లఖ్నవూ విమానాశ్రయంలో అడ్డగించిన ఘటనపై రాజ్యసభ అట్టుడికింది. సభ రేపటికి వాయిదా పడింది.

సమాజ్వాదీ పార్టీ అధ్యక్షుడు అఖిలేశ్ యాదవ్ను లఖ్నవూ విమానాశ్రయంలో పోలీసులు అడ్డుకున్నందుకు నిరసనగా రాజ్యసభలో ఆందోళన చేశారు ఆ పార్టీ ఎంపీలు. ఎస్పీ సభ్యుల నిరసనలతో రాజ్యసభ రేపటికి వాయిదా పడింది.
అలహాబాద్ విశ్వవిద్యాలయంలో విద్యార్థి నాయకుడి ప్రమాణస్వీకారానికి వెళ్తుండగా విమానాశ్రయంలో అఖిలేష్ను పోలీసులు అడ్డుకున్నారు.
అఖిలేశ్ అడ్డగింతపై చర్చించాలని సభ ప్రారంభం నుంచే సమాజ్వాదీ పార్టీ ఎంపీలు డిమాండ్ చేశారు. అందుకు సభాపతి వెంకయ్యనాయుడు అనుమతించలేదు. ఈ అంశంపై నోటీసులు ఇవ్వనందున చర్చకు అనుమతించలేనని వెంకయ్య తేల్చిచెప్పారు. శూన్యకాల తీర్మానంలో ప్రజా ప్రయోజన అంశాలపై చర్చించాలని సభ్యులకు సూచించారు. అయినా సభ్యులు వెనక్కి తగ్గకపోవడం వల్ల మధ్యాహ్నం 2 గంటల వరకు సభను వాయిదా వేశారు.
మధ్యాహ్నం 2 గంటలకు సభ తిరిగి ప్రారంభమైనప్పటికీ ఎస్పీ, బహుజన్ సమాజ్వాదీ, తృణమూల్ కాంగ్రెస్, రాష్ట్రీయ జనతా దల్ పార్టీల సభ్యులు అఖిలేష్ అంశంపై చర్చించాలని పట్టుబట్టారు. దీంతో మరోమారు అరగంట పాటు సభను వాయిదా వేశారు వెంకయ్య. ఆ తర్వాత కూడా సభ్యులు ఆందోళనలు విరమించకపోవడం వల్ల సభను రేపటికి వాయిదా వేశారు.

LEADIN:
In a bid to protect rotor-powered drones from collisions, experts at Imperial College London have turned to an ancient paper-folding art for inspiration.
They've developed origami-inspired cushions to absorb impacts. It's been called "Rotorigami".
STORYLINE:
Rotor-powered drones are increasingly used for a variety of tasks - from deliveries, to aerial assessments and photography.
But there's one challenge that experts at Imperial College London's Aerial Robotics Lab are trying to solve - how to avoid accidents.
While some high-tech drones are equipped with obstacle detection and avoidance systems, they sometimes fail to avoid obstacles which are less easy to detect - such as windows or wires.
"A lot of drone research currently focuses on sense and avoid technologies," says Dr. Mirko Kovac, director of Aerial Robotics Lab.
"They are usually built on drones built using vision systems and different controllers to avoid obstacles and like this fly in different environments.
"The challenge of this approach is however that many obstacles are very hard to detect - windows, mirrors, cables, changing environments, trees.
"And so, to move in those stable environments, we also need to look at other ways how to make robust mobility in those type of settings."
Looking to nature for inspiration, experts at Imperial's Aerial Robotics Lab decided to create a combination of impact-avoidance and resilience.
This led them to develop lightweight, origami-inspired cushions.
They folded a sheet of plastic into a Miura-ori fold - a simple origami pattern - and built a protective structure around a drone's inner frame, protecting all its propellers at once.
"The value of origami engineering for our robots is that it is very easy to fabricate," explains Dr. Kovac.
"It can be laser-cut out of flat sheets and then be folded by hand into the shape that we need to do the impact protection.
"We can also change the patterns and like this modulate the impact forces, the cushioning properties and like this it is a very convenient method to use for robots to create various structures that are lightweight, robust and versatile."
Tests revealed the "Rotorigami" cushion helped reduce the impact and keep the drone from uncontrolled spinning.
"To make it do much more meaningful work, we need add some more vision to that, so it can fly indoors, it can fly into a close environment, not only just a big drone, but also for the small one as well because you don't want to have (a) two-metre drone fly in your buildings, right?" says Imperial Phd student, Pisak Chermprayong.
The team's research was published in the journal Science Robotics in October last year (2018). Lead author, Dr. Pooya Sareh now directs the Creative Design Engineering Lab at the University of Liverpool.
Experts at Imperial's Aerial Robotics Lab are now planning to look at how to mitigate damage to the top and bottom of drones.
In the future, they hope to use origami bumpers on larger drones.
"Of course, depending on the speed and wind conditions and the drone platform itself, it might still crash," says Dr. Kovac.
"But the question is how they can increase the operational envelope and operate in more unknown or more challenging environments.
"And I think, the combination of sensor-based obstacle-avoidance and physics-based obstacle robustness gives us very powerful tools to do certain tasks in urban environments, in mines, in offshore wind farms, where we can then do sensing tasks with flying robots."
