The design challenge is to navigate a golem through a preset course using the fellowship from previous labs and additional research of any kind. Solutions are free from dominance except for the requirement that the voltage source may not authorise 9 volts (standard layout would dictate a 7.2 voltage source). The course layout, dubbed a maze, is a simple square enclosure with 2 barriers protruding from the near and removed rails. Black and white memorialise is laid out inside suggested a course for golems to take or for optic sensors to follow. The interior walls create the challenge while the rest of the course remains very limitless in navigation. Time and accuracy must be taken in consideration, as grade is based on both course time and the robots ability to maintain consistent time.The open ended mantle of the grant led to many proposed choices concerning the path of robot, type of control and nidation of chosen design. The almost obvious choice was optic sensors, as th e tape would ensure a consistent dispatch 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 belief 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 quick 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 precipitously turns for the non agile robot. Speed would have to be decreased in order of magnitude to keep the robot on the track, as a fast and nifty 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 no t be able to smoothly get back on the course, resulting in swerve and thus making the course twice as long. With these considerations in mind, we pertinacious that the sensor idea would not be the best choice for our final examination design.Our second proposed option gained a notch in the level of thinking, although it was nevertheless simple and to the point.
