The visual simulation displays:
• A specific agents traversability or visibility map upon request • A background image unique to that scenario
• Agents moving around the workspace area
• Current agent’s actions
IV. METHODS
The simulation’s primary goal is to confirm the author’s claim that implementing the method outlined in Failure An- ticipation in Pursuit-Evasion will provide the ability to get assistance to the primary pursuer within the visibility criteria.
This claim is tested using all three scenarios mentioned above.

The secondary goal is to measure the amount of time it takes to discover potential failures as the time horizon increases. A regression analysis is performed on the data to determine the rate of change. The rate of chance is then compared to the author’s results. The goal is to have the rate of change less than the O(h3) limit cited by the authors.
Searching problems can be studied using many different constraints on the problem (Fig. 2). Failure Anticipation in
Pursuit-Evasion mentions about some the constraints the au- thors decided to use but not all of their decisions. The authors specified heterogeneous search group, use of a finite discrete graph and number of targets. This leaves a lot of implemen- tation details such as target’s motion, pursuer’s motion and pursuer’s sensory model that are not explicitly stated. The lack of details on those topics is expected because the algorithm discussed in the paper does not focus on these items. But, the lack of these details add uncertainty when attempting to replicate and evaluate their results.
There are also a few important difference between this paper’s implementation and the methods described in Failure

...l exploration task. If the high value pursuer could take target location into account while still exploring the environment you could greatly reduce the cost of providing support while increasing the likelihood that the visibility criteria will always be met.
Sixth, apply D*-lite ideas to the failure prediction algorithm to get better performance. Between time steps the failure prediction graph nodes don’t change very much. You could leverage this by caching and reusing the nodes, similar to
D*-lite, between failure checks to greatly reduce the cost of predicting potential visibility failure.

When people hear the term “FIRST Robotics” or hear anything related to robotics, they automatically assume that it has something to do with robots destroying each other or nerds sitting in the corner eating pizza and building small robots; I used to be one of those people who thought that before joining FIRST Robotics. In all honesty, I was very reluctant on becoming a part of FIRST Robotics in the first place because I did not know if I would fit in or even enjoy it for that matter. However, thanks to two special people I gave FIRST Robotics a shot, and I’m thankful that I did because I wouldn’t be the person that I am today. FIRST Robotics has greatly impacted my high school experience by teaching me life skills that I can’t learn in the classroom, forming new bonds and

First Robotics Competition, or FRC, is a progeam designed for highschool studenbts. Where in they are given a challenge then recieve 6 weeks to design, build and program a brand new robot, before heading off to competetion. This year the game was First Power up, where teams could deliver power cubes to either the small switches, the massive scale, or place them in the exchange for power ups. The robot, "TacocaT", the NERDS designed for this is an inventive and well desinged rbobot, from its use of chasis space, to its pnuematic claw and arm.

In the short story “Runaround”, published in 1942, the author Isaac Asimov introduced Three Laws of Robotics to his readers. Briefly speaking, these laws prohibited a robot from injuring or killing a human being under any condition, even if its owner asked it to do so. However, by the end of year 2008, there were around 12,000 U.S. military robots on the ground in Iraq (Singer, 2011). It seems like the three laws of robotics do not apply to the real world. It is natural to think that the use of military robotics will reduce the casualties of their interested parties, but, in reality, robots can be out of control due to various reasons, including technical errors and unethical commands from programmers or commanders. This article will illustrate the advantages and disadvantages of military robotics in battlefields, and discuss the need for adaptations of ethical rules in a world of artificial intelligence.
Thesis Statement: The number of disposable relationships in the workplace is predominant due to the increasing adaptation to artificial intelligence to produce the same level of work for a cheaper cost.
Robots are not a better, cleaner breed than humans are. The reason for this being is that as they get more powerful they can do more dangerous things and will become smarter than human beings.
Several military robotic automation systems already operate at the level where the human is still in charge and responsible for the deployment of lethal force, but not in a directly supervisory manner. The Phalanx system for Aegis-class cruisers in the Navy is designed to be the last line of defense against anti-ship missiles. The gun mount moves with rapid precision. The system takes a low amount of input from the ship, making it capable of functioning despite potential damage to the ship. There are several settings for the Phalanx system, with the final fail safe setting of “casualty” that will defend the ship from air attacks without human selection of targets. The MK 69 encapsulated torpedo (CAPTOR) sea mine system was the U.S. Navy's standard anti-submarine mine during the Cold War, having enough computer power t...

In her article “Alone Together: The Robotic Movement,” Sherry Turkle describes how our current generation has transformed due to technology advancement, especially with robots. Inventions of robots have become familiar in almost all countries, particularly in japan she explains how technology has changed the basic human interaction to conversations in electronic devices.
The concept of weaponized autonomous robots is heavily debated due to the ethical implications their existence poses. Over the years, the stance on how to approach such a topic has drastically changed with the need to create newer weapons for the military to compete with potential threats from other nations. As this paper will discuss, what used to be a precautionary approach when discussing robot autonomy has now taken a backseat to the rushed development of these weapons. The research of this technology has now produced an arms race, as predicted by writers from the past who warned us about the issues that may rise from creating such weapons before establishing a mutually agreed upon code of conduct. Being that there were no real boundaries on this type of technology in the pre-2010 era, many researchers sought to establish guidelines. But their attempts seemed to have fallen on deaf ears when many experts today agree that such weaponry inevitably under production due to the power
There are many agencies that have the ability to perform Signals Intelligence, electronic reconnaissance and most of all signals intelligence from all available sources inducive to the environment. The United States Army uses the Joint Surveillance Target Attack Radar System (Joint STARS) as its main entity for signals collection. The Joint STARS platform was designed to provide a highly effective, real-time, collection tool to the ground task force commanders during battlefield engagements, but for the past ten years, the sensor has been used for peacekeeping missions. Army analysts can predict the enemy’s behavior by identifying choke points, potential avenues of approach and operating patterns such as supply routes and logistical points. The analysis gives the ground commander a more complete view of the enemy’s weaknesses. The United States Air Force employs the Joint STARS in a different mission than the Army. The Air Force uses Joint STARS as a battlefield management tool versus a collection tool as used for by the Army. The Air Force uses the platform to provide immediate and direct support to the Air Component Commander and continue to observe the enemy’s movement from a far distance in the sky. Providing essential data to commanders such as size, direction, and speed of the adversaries, with minimum casualties while under battlefield conditions, makes the Joint STARS an extremely effective tool. The Air Force also employs the Predator vehicles, which are unmanned aerial vehicles that are used for reconnaissance.
The study will critically analyze the Functional Movement Screen developed by Cook, et al., (2006). According to Schneiders, et al., (2010), “the Functional Movement Screen was developed as a comprehensive pre-participation and pre-season screen tool that challenges an individual’s ability to perform basic movement patterns ” (p.76). Cook, et al., (2006) developed the FMS when there was not a functional evaluation standard to make rehabilitation protocols that take into account how a patient functionally moves (p.62). The FMS is an evaluation tool that is comprised of 7 fundamental movements to assess an individual mobility and stability (Cook, et al., 2006, p.63). Observation has indicated that athletes cannot perform
Disastrous nature such as earthquake, flooding, or tornados gives a big impact to the affected area. These kinds of catastrophe cause another disaster such a landslide or collapsed building that may claim many lives. During this critical situation, people especially police, fire department are deployed in search and rescue mission to save countless life and of course under the circumstance their well being are put on high risk and expose to danger. Hence, the robot are build to replace human when it comes to difficult task and involving in critical situation neither human or tools can do. They are variety types of robot are build to do the different tasks depends on their specialty. For example the search and rescue (SAR) robot are designed to assist human to search and rescue victims in urban disaster. According to Burion (2004) this autonomous robot must be able to helps rescuers to determine the location, condition of the victims by having the different sensor ability to operate under condition with many unknown parameter. SAR robot can be either semi-au...
