Indian ROV monitors the health of coral reefs

Scuba divers who take a plunge into ocean floors to study coral reefs can now take a break. An indigenously developed remotely operated vehicle (ROV) is taking up their role with more efficiency and accuracy and it’s expected to contribute significantly to the conservation and management of corals.

The National Institute of Ocean Technology (NIOT), Chennai, had recently deployed the ROV for studying the coral reefs of the Andaman and Nicobar Islands, which are facing survival threats due to global warming.

While it would take weeks together for a scuba diver to diagnose the health of corals, the ROV could map a larger area in a day.

“The images of corals recorded by the ROV are useful for studying the biodiversity of coral reefs and their evolution. The underwater visuals had shown the coral debris and boulders caused by the 2004 tsunami and the rejuvenation of the colonies of branching corals, stony coral and brain corals at some locations,” explained G.A. Ramadass, Head, Deep Sea Technologies Group, NIOT.

The coral reef biodiversity at Andaman region, which spreads across an area of 11,000 sq km, was seriously affected during the 2004 tsunami. The increasing sea surface temperature added to the stress. Currently, there is no mechanism other than scuba diving to examine the corals and assess the extent of damage or rejuvenation,” explained Dr. Ramadass.

According to the experts, no evidence of coral bleaching was seen in Andaman reef during April 2016 when the ROV carried out a survey. However, the ecosystem needs to be monitored constantly to understand the impacts of raise in temperature, he said.

Development of ROV

NIOT had earlier developed a deep water work class Remotely Operated Vehicle (ROV) ROSUB 6000 which was suitable for exploration in deep waters. It was successfully operated at a maximum depth at 5,289 metres in the Central Indian Ocean Basin. It also contributed to the exploration of deep ocean minerals such as gas hydrates, polymetallic nodules and hydrothermal sulphides, which occur at water depths ranging between 1,000 and 6,000 metres, said a communication from the institute.

A new miniaturised version of ROV, which could be effectively used for exploration and inspection up to 500-metre water depths, caters to the need of the research community and industry. It was also deployed for scientific research in Antarctica as a part of the 34th Indian Scientific Expedition to Antarctica during Jan-Apr 2015. It was deployed in the Lake Priyadarshini near the Indian permanent station Maitri and in the New Indian barrier ice shelf regions.

Geek Speak: Navaratri Special Edition

It’s the final day of Navratri and we couldn’t be more happier. Called the day of Vijayadasami, it signifies the day when good trounces evil. While there had no battle against evil here at Kidobotikz, there was one stiff competition underway though- the competition to get robots on the Kolu stairs. 

Upon announcement of the Kolu display at Kidobotikz, dozens of students visited the center and were eager to get their robots on display. Students spent the first half of their dusshera holidays developing their Kolu-themed projects. The next half was spent displaying these on the stands at Kidobotikz. Quite a few number of entries were received and owing to space constraints, a few of them had to be not displayed at the stands. We’ve picked a few of the projects that had turned quite a few heads and have featured them here.

1) Thirumalai Thirupathi Oonjal Sevai by A.V Sangeetha

The theme of this project is to emulate the traditional swing on which the deity at Tirupati is customarily placed upon as a part of the Brahmotsavam celebrations. This project, done by Kidobotikzian A.V Sangeetha, makes use of a couple of B.O motors, and an arduino board to induce an oscillatory motion in the motors. Suspended from the B.O Motors is the Oonjal.

2) Blessing Ganesh by A Shiekh and S. Sai Manivanan 

Using nothing but a starter shield and a BO motor, these young roboticists have created a Blessing Ganesh picture frame that has an automated trunk. Whenever, one takes their arm near the image, the trunk of Lord Ganesh will rise up and bless the devotee.

3) Automated Kumkum and Manjal offering by Mrithun Chockalingam 

This project is a rather neat looking one with a lot of functionality built into it. There’s an idol of Lord Ganesh in the middle with a small motor mounted umbrella behind him. In the front, the two small cups of kumkum and turmeric are placed on small plates. These are connected to two BO motors that are concealed below the boxes. The motors are connected to IR sensors. So, when someone brings their palms near to Lord ganesha to touch his feet, the sensors detect the palms and the small motors rotate the containers above.

4) Ranganatha being fanned by Balaji S.Rao 

To add some robotics to mythology, Balaji Rao came up with this concept. It depicts the image of how Lord Ranganatha is fanned while he rests upon a serpent in his holy abode. Balaji made a slow rotating fan with a torque motor that will look like someone is fanning the god. To achieve the same, he has used a custom made fan blade and connected it to a BO motor via a long stick. 

We wish all a very happy Navaratri and hope to see more such interesting projects next year.

Happy Roboting !

Komatsu's robotic mining truck completely dumps the driver

Komatsu's latest autonomous truck fully embraces the notion of unmanned operation by ditching the cabin and adopting a design that optimizes load distribution and doesn't distinguish between forwards and backwards.

Komatsu began trials of its Autonomous Haulage Systems (AHS) in a partnership with mining company Rio Tinto in 2008, and since then the technology has hauled hundreds of millions of tonnes of material in Chile and Australia's Pilbara region.

The autonomous haul trucks like the 930E model used by Rio Tinto incorporate controls, wireless networking and obstacle detection to enable unmanned operation, but they still look like conventional mining trucks complete with driver cabins.

The new 2,014-kW (2,700-hp), 15-m (49-ft) long and 8.5-meter (27-ft) wide "Innovative Autonomous Haulage Vehicle" takes things up a notch. The cabin is completely gone, allowing for a design that better distributes weight to all four wheels, and it uses four wheel drive and four wheel steering for better grip and maneuverability.

Without the need for a driver squinting in the rear view mirror, the truck is also designed to move as efficiently backwards as it does forwards, meaning no three point turns and therefore increased productivity and less wear and tear on the 59/80R63 tires. It can handle a payload of 230 metric tons and reaches a maximum speed of 64 km/h (40 mph).

The robot monster truck is being unveiled at Minexpo International in Las Vegas this week and Komatsu says it "plans a market introduction in the near future."

The video below is Komatsu's animation of the Innovative Autonomous Haulage Vehicle at work.

SenseFly gives its eBee agriculture drone bigger wings

A few years back, drone-maker senseFly launched its eBee fixed-wing drone with a firm eye on agricultural applications, though the drone's mapping capabilities drew the attention of those working on search and rescue applications, too. Now the company has announced an upgrade, the eBee Plus, which along with longer flight times, packs a new sensor promised to provide more precise mapping.

 The eBee Plus looks much like the original drone on the outside, but it packs a little more functionality inside that senseFly and parent company Parrot will hope can expand its appeal. This includes a new propriety sensor dubbed S.O.D.A (Sensor Optimized for Drone Applications), an RGB camera with a 1-inch sensor, and global shutter that is capable of snapping images with a spatial resolution of 2.9 cm (1.1 in) while flying at an altitude of 122 m (400 ft).

The wingspan has grown from 96 cm (37.8 in) to 110 cm (43.3 in) and flight time is boosted from 45 minutes to 59 minutes, allowing the drone to map 220 ha (540 ac) on a single flight. The company claims this is more area than any drone in its weight class. Routes are planned through the senseFly's accompanying flight-control software, eMotion 3, which allows for multi-drone missions and also handles the data management.

While the drone comes loaded with the S.O.D.A sensor, this can be swapped out for any of the company's fixed-wing RGB, thermal or multispectral sensors, such as the Sequoia released earlier this year. There is also the addition of RTK/PPK functionality which is available as an optional extra and draws on satellite data for more precise positioning information about objects on the ground.

The company will be showing off the new drone at mapping conference Intergeo in Hamburg next week. Though there is no information on the pricing for the eBee Plus available at this stage, we have enquired with senseFly and will update the story when we hear back.

Geek Speak: Mrithun Chockalingam

It’s Saraswati pooja day and most of them young students must be happy! It’s the only mandated day of the year when students are requested to NOT touch their books! And it is something of a calm before the storm because most of these students will be burning their midnight oil the very next day, Vijayadasami, in time for schools that reopen. 

But, roboting requires no books. So, there’s no embargo for robotics on Saraswathi Pooja day. This means most of the Kidobotikzians are here doing the same regular roboting stuff that they are used to doing. Meanwhile, we pick up from from where we left yesterday and cover students who have presented their Kolu-themed projects here at Kidobotikz. With us today is someone who has truly taken the art of Athithi Satkar, or Guest Hospitality, to a new level. He’s come up with an innovative way of serving Kumkum and Turmeric to the guests who visit his home for Navaratri. Meet Mrithun Chockalingam our Geek for the day. 

Hi Mrithun! Can you tell us the inspiration behind your project?

For every kolu, neighbours and relatives visit our home. When they leave, it is customary for my mother to give them Kumkum and turmeric placed near the deity. I wanted to make it easy so that as and when the guests offered their prayers to the Idols they got offered the holy powders automatically. That was the inspiration behind this project.

To make it work, I placed the idol of Lord Ganesh in the middle and erected a small motor mounted umbrella behind him. If you notice the front, the two small cups of kumkum and turmeric are placed on small plates. These are actually connected to two BO motors that are concealed below the boxes. The motors are connected to IR sensors. So, when someone brings their palms near to Lord ganesha to touch his feet, the sensors detect the palms and the small motors rotate the containers above.

 Inspiring! Must be interesting learning to know how to do all these! 

Yes, all of these are quite interesting to make work. Thanks to my curiosity and basic knowledge of robotics, I was able to do this. Not just my parents, all the guests who visited my home were also equally impressed. 

So, how’s your roboting experience at Kidobotikz and How did you actually join Kidobotikz 

Thanks to Kidobotikz, I now know that Robotics is not as complex as portrayed. I am now in the Foundation level and it is exciting to know that from here onwards, I get to build cool robots like Sumo Robots and Hexapods.

What is your favourite Robot?

My favourite robots are Humanoids. In particular, I have a fascination for the ASIMO series of robots built by Honda.

What are your future ambitions? Where do you see yourself in the future now that you are a budding roboticist?

I wanna be an Automobile designer when I grow up. I have a fascination for Cars and their designs. So, when I grow up that’s where I see myself. Also, now that I am into the field of robotics, I wanna explore the possibilities of Autonomous cars and cars that can be controlled with mobile phones.

Panasonic uses human touch to transfer data

Panasonic suggests that because the data is traveling through the body and not through the air, secure transmission is assured

In an age when digital information can fly around the connected networks of the world in the blink of an eye, it may seem a little old timey to consider delivering messages by hand. But that's precisely what Panasonic is doing at CEATEC this week. The company is demonstrating a prototype communication system where data is transmitted from one person to another through touch.

There's very little information on the system available, but Panasonic says that the prototype uses electric field communication technology to move data from "thing-to-thing, human-to-human and human-to-thing." Data transfer and authentication occurs when the objects or people touch, with digital information stored in a source tag instantaneously moving to a receiver module – kind of like NFC tap to connect technology, but with people in the equation as well as devices.

The LEDs under one staff member's skirt change to match the color of a bracelet worn by another when they shake hands

It has the potential to allow business types to exchange contact information with a handshake, mood lighting in a room to be changed to match or contrast with clothing when a lamp is touched or access to a building granted by placing a hand or object on a lock interface or door handle. And Panasonic suggests that because the data is traveling through the body and not over the air, secure transmission is assured.

The CEATEC demos are quite basic, but serve to show that the system works. There's no word at the moment on whether it will make it to enterprise or commercial availability, but the video below shows the Human Body Communication Device in action.

Geek Speak: Balaji

Ah, finally the weekend of Navaratri is here! It’s been a week full of roboting for most of these students! With the schools drawn to a close for the pooja holidays, students have been caught up in making robots in line with the festival season. With Kidobotikz also setting up a robotics Kolu on the premises, quite a lot of them pitched in and decided to display their Kolu-themed projects on the Kolu pedestal. Apart from this, an enthusiastic few have also taken to adorning the Kolu steps at their own homes with robots. A bunch of these young roboticists have taken videos of their Kolu-bots in action and uploaded them onto YouTube.

With us today is one of these fellas who has put his project on the Kolu stands at Kidobotikz. We enquire more about his project and his unique way of celebrating navaratri. Meet Balaji S. Rao, 3rd Grader at PSBB KK Nagar and a Kidobotikzian in the Foundation level. His project is a impressive looking figurine of Shri Ranganatha Swamy that is being fanned by a robot. Let’s learn more about him and his project . . . .

Hi Balaji! Can you tell us the reason behind your project?

Well, the tradition of Kolu is usually depicting scenes from mythology in the form of small dolls and figurines that can explain the story to guests and visitors during the Navaratri festival. I wanted to come up with something like that and some robotic effects to it. So, I made a slowly rotating fan that will look like someone is fanning the god. That is my project. For that I used a custom made fan blade and connected it to a BO motor via a long stick. 

Very good! Can you tell me how you made this project?

It was my own idea. But then, i wanted some help with motor and mounting the fan. So, I took some guidance from my brother who is also a student here at Kidobotikz and some assistance from my faculty. 

Can you tell us how goes your journey at Kidobotikz?

I am in the final stages of my Foundation level. I am hoping to finish the foundation level soon and commence the beginner level. Beginner level is where I get to work on robots with wheels and I am quite excited about the same. 

What are your favourite robots?

My favourite robots are Bipeds, the ones that are capable of walking on two legs. ASIMO is the best robot according to me. Another favourite would be amazon’s Kiva.

What’re your future plans? Where do you want to study? 

I want to become a robotics engineer. But I have not planned where I will study. I will probably ask my brother’s suggestion before doing that.
