I only noticed it now

They took my illustrated pic , did surgery on it, and used the same.

I have absolutely no problem anybody using any resources I post ( except those in spoilers ) but nevertheless it is a honourable thing to give credit where credit is due, same as one would expect from others in return.

 

[Bajirao]

Yes

And I am assuming dhruvastra also has the same.

sant also has two side thruster like helina but it's nozzle is like land version of nag.

@Bleh @porky_kicker @patriots @Karthi

do u guys know if we have home made bunker busting bombs like shown in this video?

the bunker busting bomb is shown still 2:55 and after that lot of glide bombs are shown. i hope our home made glide bombs will be as good and accurate as shown in the video.

any comments

Wind tunnel model of one has already been posted in this thread.

I think the previous version of NAG and HeliNa is dead. now the only contender is MPATGM, Latest version Dhruvastra with JVC and SANT. There will be a combination of the seekers as per required for Army and airforce

No,it's not dead.nag trial is complete and has got dac approval,contract may be going to be signed in near future.helina user trial will be completed in this financial year and will be main weapon against armour.

To help people with severe speech and motor impairment, researchers
@designatiisc have developed a robotic arm that can be manipulated by eye movement using a webcam and computer interface. https://iisc.ac.in/events/eye-gaze-controlled-robotic-arm-for-the-speech-and-motor-impaired/…





Eye gaze-controlled robotic arm for the speech and motor impaired



– Anoushka Dasgupta
People with Severe Speech and Motor Impairment (SSMI) ‒ a condition caused by disorders like cerebral palsy ‒ find it difficult to physically operate devices such as a joystick, mouse or trackball, or use speech recognition systems. Eye gaze-controlled computer interfaces can help them perform various tasks on par with their non-disabled peers.
To help people with SSMI, a research team at the Centre for Product Design and Manufacturing (CPDM), Indian Institute of Science (IISc), has designed a robotic arm that can be manipulated by eye movement using a computer interface. This interface is non-invasive since it is through a webcam and a computer, unlike other eye gaze-tracking devices that use head-mounted systems.

The team worked with young adult students who have SSMI at Vidya Sagar (formerly The Spastics Society of India) in Chennai, an institution for individuals with disabilities. “Many of these students [with cerebral palsy] are not able to precisely focus at a single point in their visual field, due to uncontrolled gaze movement. They are also not comfortable to look at all portions of the visual field equally,” says project lead Pradipta Biswas, Assistant Professor at CPDM.
Biswas and his team used computer vision and machine learning algorithms to analyse live feeds of facial video from the users, and were able to estimate where the user was looking. They coupled this with an Augmented Reality application to allow the user to use a robotic arm for tasks like picking up and dropping objects, and placing them where they desire, as long as it was within reach of the robotic arm.
One of the main applications of this eye gaze-controlled robotic arm is rehabilitation of young adults with SSMI, through tasks such as fabric printing. They usually require assistance in doing such tasks, as they can only do a small part of it by themselves. Using the robotic arm designed by the researchers, people with SSMI can use their eye gaze to perform mechanical tasks that can help them work on handicrafts independently.

This eye gaze-controlled interface has been deployed at Vidya Sagar and is in regular use. “This validation and evaluation [of the interface and robotic arm] with end users is a major contribution of the study,” says Biswas. The students with SSMI are able to use the robotic manipulator almost as well as their non-disabled counterparts, and the results were the same during repeated trials.
This technology can also be used by younger individuals with SSMI, to move toys like cars. “We are using play as a medium to teach new technologies, which they can use for the rest of their lives,” adds Biswas. Further modifications to this tool could also allow young individuals with SSMI to use it for e-learning.
The authors believe that this interface is a step towards designing future technologies which ensure that physical impairments do not stand in the way of pedagogical training and professional lives of individuals with SSMI. Biswas also says that such a system could be useful for automotive and aeronautical applications, as well as for developing collaborative robots used in smart manufacturing.

This could be the seeker for MPDMS , not guaranteed though

It's diameter is 120 , in tender of MPDMS the ZnS dome diameter is 100 . 10 mm on either side could be the thickness of the frame body on which the dome fits in.

And who say's we are not making any progress . Conference after conference , meeing's after meeting's , and finally the files closed .

Same has been sold to Myanmar navy.
These small projects are where these type of companies can shine.

L&T's Amogh AUV can stay underwater for 22 hours and can operate at 1000m below surface.

Th AUVs hav become an essential component of oceanographic s

urveys, underwater surveillance and reconnaissance. The Amogh can run autonomous. The primary function is to make a 3D map of ocean's surface as detect sub surface objects as a reconnaissance mission. Amogh can also conduct Surveillance by constantly unting for hostile subsurface objects.

Amogh is equipped with Multi-beam Swath Bathymetry System, Side-scan SONAR, Obstruction avoidance Sonar, Sub-bottom profiler, Underwater camera.

Is it tested in Italy......any reason behind it?

Is it tested in Italy......any reason behind it?

May be For better testing facilities , may be for testing in different locations to test the properties . Don't know any other particular reason

L&T collaborated with Edgelab (Italy) for amogh AUV

L&T collaborated with Edgelab (Italy) for amogh AUV

But the difference between a psu collaboration with foreign company and a company like L&T would be in learning and implementation. The difference will be seen in the next iteration.

Bdw @porky_kicker ...is there any aps in development for tanks...
Bdw drdo is going to test advanced light weight torpedo from seaking helicopter.....(info from various tender documents)
May be some uninformed missile tests also happening (info-from local sources)
The India china face off...paced up tests
