Introduction
The purpose of this experiment was to design a robot that could complete a maze on its own. A blueprint of the maze to be completed was given to the team and the physical maze on which the robot would be tested was available for experimental trials. Within the maze there is white duct tape placed on the floor, with black duct tape placed on each side of it. This tape runs from the entrance of the maze to the exit as shown by the red line in Figure 1. Within the maze there are also bonus blocks, indicated by the blue blocks in Figure 1. The team will be granted three trials, during which the goal is to complete the maze as quickly as possible and earn as many of the bonus point as possible.

Materials and Methods
For the construction of the robot, only the Lego pieces and sensors provided in the tackle box were used. The design of the robot was modified from the original versions however, with the following specifications. The wheels were positioned in the front part of the robot, thus changing the axis of rotation to the front of the robot when it turned. Instead of the conventional four wheel design, the two rear wheels were replaced with a single pivoting wheel, thus reducing the resistance when turning. Finally, an ultrasonic sensor and sound sensor were mounted at the front of the robot as shown in Figure 2.

The team decided unanimously to take the software approach to the project, and use LabView to write a program which would allow the robot to complete the maze. Before any program was written however, the team spend time evaluating different suggestions on how to approach the problem. Each of these solutions presented benefits and drawbacks, and these were each assessed before decidin...

...is project was not completed in its entirety as a whole, but rather broken down into components of problem solving. The team first evaluated the goal of the project, and spent time discussing the benefits and drawbacks of each of the designs suggested. After the team had agreed on which approach to take came the task of modifying the robot to meet the needs of the proposed design. The most time consuming part of the project was programming the software and testing it as new coding as added to each of the programs, evaluating which of the ideas worked and which did not. After the first time that the robot completed the maze it was tested repeatedly to ensure that the program would work as expect in each of the trial runs. Thus throughout the course of this project the team implemented the common steps needed when solving problems – evaluating, designing, and testing.
Throughout this essay I will be analysing a sixty second sequence of the film I-Robot. Directed by Alex Proyas, the film was released in 2004 and was a hit at the box office. The film is an action-thriller inspired by Isaac Asimov’s classic short story collection. Asimov’s books set forth the three laws of robotics.
It was midday when Mission Control got the alert that there was a trapped miner. The report had said that a miner was trapped under some rocks that had fallen tumbling onto the miner. Mission Control immediately got Gemini-Scout prepared for the mission in the mine. Gemini-Scout was transported to the mine where the miner was stuck. “Ok Gemini are you ready?” asked Adam, who was specially trained to control Gemini. Beep boop went the robot

Being on a First Robotics team, Cat Attack team 451, was a lot of fun during high school, but it’s quite stressful as well. Every year in January, the game is announced and we are given six weeks to build a robot. The stress comes from having to build a fully functioning robot in such a short time. The total time we meet and worked adds up to be 64 hours. During these 64 hours: We found out what the function of the robotic is supposed to be able to do “is it suppose to climb or throw.” After that we brain stormed on the design and build of the robot. will be doing.

Moreover, Bill works for the state highway patrol (OSP). One evening he brought in colleagues to come in and speak about distracted driving and its dangers. They brought in a distracted driving simulator to demonstrate the effects of dangerous driving in real time. Additionally, 2 years ago Bill brought an OSP bomb robot to the Buckeye Regional in Cleveland, Ohio. This showed that what we do as FIRST students really applies to life after high school. That the knowledge we gain from programing and building our robots will benefit us in many career paths that we may
Casey goes to an amusement park with her classmates from psychology and is put in a maze. They blindfold her and spin her until she loses all sense of direction, then they take off the blindfold and she has to try and make her way out of the giant wall maze. There are many factors that Casey will use that will either assist or impede her efforts to exit the maze. Some of factors are top-down processing, functional fixedness, means-end analysis, confirmational bias and bottom-up processing.

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.

Several simulation experiments on pattern recognition and writing will be carried out on an arm type robot simulator, which is in a graphical environment in order to evaluate the performance of the prototype learning module on writing. The arm type robot simulator is going to be model and simulated using Robotics Toolbox for MATLAB that proposed by Peter Corke (2011). The robot simulator will learn how to write using the prototype learning module. The performance of the robot simulator on writing will be recorded for data analysis. And there is no user will be recruited in the evaluation on the performance of the prototype learning module.
The open ended ness of the assignment led to many proposed choices concerning the path of robot, type of control and implantation of chosen design. The most obvious choice was optic sensors, as the tape would ensure a consistent route through the maze and the most accurate times. The design would be as obvious as the route: two sensors controlling the speed or direction of the wheels. When one sensor drifted from the light the wheels would compensate to bring the robot back on track. The idea seemed simple and a sure way to rapidly complete the assignment without trouble. Further thought engendered many concerns: not only must the robot navigate the course but it must also do it faster than the competing teams. Sensors would ensure the robot would cross the finish line, but not with a fast time. The course the sensors must take is loopy and has somewhat sharp turns for the non agile robot. Speed would have to be decreased in order to keep the robot on the track, as a fast and sharp turn could throw the robot off the tape, destroying any possibility of a finish. Another problem arose with sensitivity. The robot, once of the tape a little, would not be able to smoothly get back on the course, resulting in swerving and thus making the course twice as long. With these considerations in mind, we decided that the sensor idea would not be the best choice for our final design.
Over the years mankind has advanced greatly in the field of technology and day by day we continue to advance. The future holds many possibilities, one of which is living in a world with robots. Isaac Asimov shared his view of this possible future in his novel I, Robot. His view portrays robots as machines superior to humans mentally and physically. If robots are superior to humans, how do humans control the robots? Humans create the three Laws of Robotics, which are instilled into the positronic brains of every robot created.

To conclude, robots could be the backbone of the society that will result in a technological revolution. Because of robots various characteristics that do not experience fear, nor exhaustion and they are precisely programmed, which make them able to help in case of need, housework, and factories production. Society needs to put the issue of robots into consideration to satisfy any shortage exists in the world.
