Tracking Sharks With Robots
Scientists have been tracking sharks with robots for a long time However, a new model is able to do this while tracking the animal. The system was created by biologists from Mote Marine Laboratory, and engineers from Harvey Mudd College using components that were readily available.
It is able to endure a pull-off force that is that is 340 times stronger than its own weight. It can also sense changes in objects and change its direction to accommodate them.
Autonomous Underwater Vehicles (AUVs)
Autonomous underwater vehicles (AUVs) are robotic machines that, dependent on their design they can drift, drive or glide through the ocean with no real-time supervision from human operators. They come with sensors that monitor water parameters, search and map features of the ocean's geology as well as habitats, and more.
They are usually controlled from a surface vessel using Wi-Fi or an audio link to transmit data back to the operator. AUVS are used to collect any type of temporal or spatial samples and are able to be deployed in large groups to cover a greater area faster than is possible using the use of a single vehicle.
Similar to their counterparts on land, AUVs can navigate using GPS and the Global Navigation Satellite System (GNSS) to determine where they are in the world and how far they've been from where they started. This positioning information, along with sensors in the environment that transmit information to the computer systems onboard, allows AUVs to travel on a planned trajectory without losing track of their destination.
Once a research project is complete, the AUV will sink to the surface and then be returned to the research vessel from which it was launched. In contrast an AUV that is resident could remain in the water and conduct regular, pre-programmed checks for a period of months. In either case, the AUV will periodically surface to communicate its location via the GPS signal or an acoustic beacon, which are then transmitted to the surface ship.
Some AUVs communicate with their operator constantly via a satellite link to the research ship. This allows scientists to continue to conduct experiments from the ship even when the AUV is away collecting data under water. Other AUVs communicate with their operators at certain times. For example when they have to refill their sensors or verify their status.
In addition to providing oceanographic data, AUVs can also be utilized to search for underwater resources such as natural gas and minerals, according to Free Think. They can also be used to respond to environmental catastrophes like oil spills or tsunamis. They can also be used to monitor subsurface volcanic activity and to monitor the health of marine life, such as coral reefs and whale populations.
Curious Robots
In contrast to traditional underwater robots, which are preprogrammed to look for only one element of the ocean floor The curious robots are built to explore the surroundings and adapt to changing conditions. This is crucial, as the environment below the waves can be erratic. For instance, if water suddenly warms up it can alter the behavior of marine animals or cause an oil spill. Robots with a keen eye are able to detect these changes quickly and effectively.
One team of researchers is working on an innovative robotic system that makes use of reinforcement learning to train the robot to be curious about its surroundings. The robot, which appears like a child with a yellow jacket and a green arm, is able to recognize patterns that might signal an interesting discovery. It is also able to make decisions about what it should do next, depending on the results of its previous actions. The results of this research could be applied to create an intelligent robot capable of self-learning and adapting to changing environments.
Researchers are also using robots to explore areas that are too hazardous for humans to dive into. Woods Hole Oceanographic Institute's (WHOI), for example has a robot named WARP-AUV that is used to study shipwrecks and find them. This robot is able detect reef creatures and distinguish jellyfish and semi-transparent fish from their dim backgrounds.
This is a feat of sheer brilliance considering that it takes a long time to train a human being to do this work. The WARP-AUV's brain is trained by exposing it to thousands of images of marine life making it able to detect familiar species on its first dive. In addition to its abilities as a marine detective the WARP-AUV can send topside supervisors real-time pictures of underwater scenery and sea creatures.
Other teams are working on robots that learn by observing the same curiosity humans have. A team from the University of Washington's Paul G. Allen school of Computer Science & Engineering, for example, is exploring how robots can be taught to be curious about their surroundings. The team is part of an Honda Research Institute USA initiative to develop machines that are curious.
Remote Missions
Many uncertainties can lead to the possibility of a mission failing. Scientists aren't certain of how long mission events will take, how well parts of the spacecraft will function or if other forces or objects will interfere with the spacecraft's operation. The Remote Agent software is intended to ease these doubts by performing many of the complicated tasks that ground personnel would perform in the event that they were on DS1 during the mission.
Remote Agent is a Remote Agent software system includes a planner/scheduler, executive model-based reasoning algorithm, and a. The planner/scheduler generates a set of time-based and event-based activities known as tokens that are delivered to the executive. The executive decides how to expand the tokens into a series of commands that are transmitted directly to spacecraft.
During the experiment a DS1 crew member is available to assist in resolving any issues that arise outside of the scope of the test. All regional bureaus must follow Department guidelines for records management and keep all documentation related to the creation of a remote task.
REMUS SharkCam
Researchers have no idea of the activities of sharks beneath the surface. But scientists using an autonomous underwater vehicle called SharkCam from REMUS are beginning to break through the blue layer, and the results are both incredible and terrifying.
The SharkCam Team is a group of scientists from Woods Hole Oceanographic Institution took the SharkCam the torpedo-shaped camera and to Guadalupe Island to track and film white great sharks in their natural habitat. The 13 hours of video footage with the visuals of the acoustic tag attached to the sharks reveal much about their underwater behavior.
The REMUS sharkCam, built by Hydroid in Pocasset MA it was designed to track the location of a animal that has been tagged without disrupting their behavior or causing alarm. It employs an multidirectional ultra-short baseline navigation device to determine the range, bearing, and depth of the shark self emptying stick vacuum Bagless robot vacuum and mop combo shark (rantadi.com). It then closes in at a predetermined distance and location (left or right above or below) to film it swimming and interacting with its surroundings. It communicates with scientists on the surface every 20 seconds, and is able to accept commands to alter its relative speed or depth, as well as standoff distance.
When state best shark robot vacuum scientist Greg Skomal, WHOI engineer Amy Kukulya, Pelagios-Kakunja shark self empty robot vacuum researcher Edgar Mauricio Hoyos-Padilla of Mexico's Marine Conservation Society and REMUS SharkCam software developer Roger Stokey first envisioned tracking and filming great whites using the self-propelled torpedo, which they named REMUS SharkCam, they worried that it could disturb the sharks' movements and could scare them away from the area they were studying. But in an article recently published in the Journal of Fish Biology, Skomal and his coworkers report that despite nine bites and bumps from great whites that weighed thousands of pounds in a week of study off the coast of Guadalupe the SharkCam did not fail and revealed some interesting new behaviors about the great white shark.
The researchers were able to interpret the sharks' interactions with REMUS SharkCam, a robot that was tracking and recording the activity of four sharks that were tagged, as predatory behavior. They recorded 30 shark robot vacuum for pets interactions with the robot including bumps, simple approaches, and on nine occasions, aggressive bites by sharks which appeared to be aimed at REMUS.
