Lego Navigation System
Abstract
My project was to create a robot out of a Lego Mindstorms construction set that was capable of “knowing” where it was. The robot would head out on a random path, remember and update its location, and return to its origin on a straight line. The challenge of this project was not so much a matter of constructing the robot, but of creating a working program in the week and a half time limit. The project goal was met on the last day, thus showing that a Lego navigation system is possible.
Background
A war zone is a dangerous place, especially for the infantry. Any advantage, technological or otherwise is welcome, and any technology that spares soldiers’ lives is invaluable. Recently,

Two of the leading manufacturer’s of these robots are iRobot and the US
Marine Corps. IRobots’ PackBot EOD uses a camera/grabber, multiple sensors, and a unique tread system capable of climbing stairs in order to execute the majority of its tasks. It also has GPS. The US Marine Corps’ Dragon Runner is a rugged, four-wheeled machine with a camera and other sensors safely encased in the body. The Dragon Runner weighs roughly 16 pounds, while the PackBot is just over twice that much weight. While these robots are a great help in a war zone, the navigation system could be improved. If the robot could navigate by itself, the soldiers that previously had to operate the robot would be free to do more important tasks. By implementing a Cartesian coordinate system, I believe that these robots be programmed with a simple self-navigation system.
Procedure
The physical design of NavBot is very simple. It follows the basic design of
TankBot, as described in David Baum’s Definitive Guide to Lego Mindstorms. I chose this design as the basis of my robot due to its simplicity and ease of construction. While it follows the basic TankBot design, it has its

The new location was calculated after each straight movement.
Once NavBot had repeated the process of moving and turning the desired number of times, the program had to turn to face the origin, and head back the correct distance. First, NavBot decided in which quadrant it was in, based on it’s x and y coordinates. It could also tell if it was on either the x or y axis. It then turned to face downward if it was above the y axis, and upward if it was below
(in the case that it was on either axis, it simply faced the origin). This was so that I only had to program how to face the origin with NavBot facing one direction, as opposed to any of four directions. This is where some of the trigonometry problems really came into play. I’d planned to program how far to turn to face the origin by using trigonometry, but since that wasn’t in option, I had to come up with an alternate strategy. I tried using the Taylor series to approximate the inverse of the tangent function (the only function I needed) , but I later discovered that it was incredibly inaccurate (off by up to forty degrees even when NavBot was less than three seconds from the origin). I
Spatial learning is the ability of an organism to memorize their environment and to use this information to navigate within it. Boal et al. (2000) notes that this type of learning has been demonstrated by other inverts. It has been demonstrated that through spatial learning, octopuses can remember where they have been and have an understanding of distance, likely by utilizing a cognitive map and a working memory (Boal et al., 2000; Mather, 2006; Mather & Kuba, 2013; Stolzenburg, 1993). They also have the ability to orient themselves in space, even when displaced by experimenters and have been shown to use moving landmarks to do so (Alves et al., 2008; Boal et al., 2000; Mather, 2006; Mather & Kuba, 2013). These abilities allow them to navigate many different areas and consistently find their way home. Octopuses often forage far from home and their paths to and from the den do not usually overlap nor do they use the same route multiple times, indicating that they know where they have been and that food will no longer be available there (Boal et al., 2000; Hvorency et al., 2007; Mather, 2006; Mather & Kuba,

Over the course of history, technology has had many advancements that human beings thought they would never be able to witness in their lifetimes. Today, many people never thought they would live to see the creation of robots. However, forms
First Law: A robot must never harm a human being or, through inaction, allow any human to come to harm.
The Defense Advanced Research Projects Agency (DARPA) grand challenge is hosted a first of its kind all robotics race through the Mojave Desert from Barstow, California to Las Vegas, Nevada. Two hours before the race the contestants are given the route at which their robots will have to take in order to win the race. Once the race starts human intervention will result in disqualification. The prize for finishing in the fastest time is one million dollars. So far no one has ever finished the race the farthest robot going just over seven miles, but they have made tremendous progress.
The military use of lethally autonomous robots (LAR) is not science fiction – it is happening right now. A robot is a mechanism guided by automatic controls. Autonomous robots are able to independently maintain stability and plan action. The first generation of military robots have operated under direct human control. The most well-known military robots are “drones” or unmanned aerial vehicles. The drone system currently in use is the unmanned aerial vehicles IAI Pioneer & RQ-1 Predator which can be armed with air-to-ground missiles and remotely operated from a command center. Drones have already been used by the U.S. military for unmanned air attacks in Afghanistan, Pakistan and other war zones. (Merchant, 276).
After this recent decade of advancement in robots, the question of how efficiently a robot makes decisions is still debated. Robots have various sensors that it takes into its central processing unit that influences its decisions. The development of gyroscopes allowed for the development of self-balancing robots and have given rise to modern day humanoid style robots. Robotic engineers can now design and teach robots various intelligent thought programmed patterns and skills to solve problems similar to humans since the technology can more resemble how humans perceive the world.
Nowadays, technology is a dominant feature in the lives of people around the world. Most of daily life activities involve the use of technology which is expanding every day through scientific innovations. However, such innovations do not always occur in every part of the world, but mostly in technologically developed countries, such as South Korea, the USA and Japan. Presently, the development of robotics science has become a subject of considerable attention in those countries. According to Weng, Chen and Sun (2009, 267), “Technocrats from many developed countries, especially Japan and South Korea, are preparing for the human–robot co-existence society that they believe will emerge by 2030.” The word “robot” was introduced in the beginning of 1920th by the Czech playwright Karel Capek from the Czech word “robota”, meaning “forced labor” (Robertson 2007, 373). According to Robertson (2007, 373), robot, in practical usage, can be defined as an autonomous or semiautonomous device that is used to perform its tasks either controlled by human, fractionally controlled and with human guidance or regardless of external actions that are performed by people. Regrettably, the majority of robots in the past centuries could not operate without human control and intervention. However, the progress in robotics over the past few decades enabled humanity to achieve soaring results in creation of autonomous humanoid robots.
It is a shared truth that humans often tend to think of robots as nothing more than computer machines made of objects like metal, plastic, silicone and computer chips. However, in truth, a robot’s general purpose is more complex than some know. In order for a robot to function, it must carry out a set of arithmetic or logical operations, and programming the specs is difficult task that could take years to finish depending on the purpose of the robot.
My heart was pounding and my hands were sweaty. I couldn’t tell if I was nervous or excited. I watched breathlessly as my team-mates were in the field setting up the robot. Switching it on, precisely positioning it, and checking all the motor-controlling wires. Everything had to be done perfectly and properly otherwise the robot would be completely incapable when the match started. Finally, they fled the field and the buzzer rang indicating the start of the first practice match. The robot took off flawlessly, driving itself through the fifteen second autonomous This was only a practice match at UC Davis’s Sacramento Regional in the FIRST Robotics program, but that moment marked the culmination of six weeks of hard work. About a little over
Robots are made to run without flaws and can outperform the average worker. This is because there are fewer employees working that need to get paid. This is not a good thing as it might seem. In China, robots almost completely replace human workers to save money.
In 2010, robots are very different from the expectations set in 1965. “The latest advances in technology have led to robots that look very much like humans but are mostly able to perform only limited functions.” (Bar-Cohen 12). Yoseph Bar-Cohen and David Hanson’s book ‘The Coming Robot Revolution” is very clear ab...
The number of robots used in industry increases every year as more companies realize their many benefits. Robots are the future of the manufacturing industry. As the performance and flexibility of robots increases and their prices continue to drop, many companies will uses these added incentives to invest in the future. Soon every company that has an application for a robot will be forced to invest in one, to stay competitive in the world market.
In today's society, robots come in different types and qualities, and robots’ use was mainly in the laboratories and factories; however, that has drastically changed where their uses are changing at a high speed. In addition to that, they have spread throughout the world. The main function of robots is to replace the work that people used to do, or perform tasks that man cannot. A robot is a mechanical or virtual device that uses a computer program, or electronic circuitry, to carry out its functions. In modern science, robotics refers to the study of robots is robotics, which deals with designing, constructing, operating, and using robots and computer systems for controlling and processing information and providing feedbacks. However, as much as robots replace human labor, individuals or organizations can use them in dangerous environments that might be harmful and beneficial to humans. Therefore, to understand the logic behind the creation of robots, one should learn the pros and cons of robotics, in the current society. This is because people are using this technology without having a deep understanding of its effects. However, an objective evaluation of the use of robots, in the modern society, shows that they have a positive influence on human beings, but if the robots were overused, it could lead to a negative side. which shows why human beings should use robots wisely that will result an improvement to their societies and own lives. Robots have become interactive equipment whereby they have become part of human life. In this regard, people use them directly or indirectly to enhance the quality of their lives. However, Sharkey argues that there are ethical issues that arise because of using robots to enhance hu...
Robots are one of the artificial intelligence that made a breakthrough across all fields of life. In consequence, many research studies and projects regarding robots took place in the last decade. In addition, robots in the society could be one of the essential machines, due to their multitask system which could adjusted to any kind of performance. In general society could use these machines to fill manpower gap in short time with less cost. Therefore, robots can have huge positive effects on different fields of life such as emergency situations, daily chores, and manufacturing industry.
