There were three bump switches at the front of the robot and the wooden framework that surrounds the bump switches. These bump switches allowed the robot to know where it was on the course and where it needed to head next. They were also used to square the robot against walls on the course. Having this constant angle was essential for the robot’s consistency. The wooden framework was used to decrease the likelihood of the robot climbing up on a wall which caused the robot to not properly square up against the wall.
There was also a setup of six CdS cells on the side of the robot. All of these CdS cells allowed for a lot of error when the robot attempted to read the light.
Chassis:
Skid:
One of the most important features of the robot is the skid that is a plastic spoon connected to two pieces of wood. This skid, shown below, worked because it slid nicely on course surface, and it never got caught on parts of the course.
Wrench and Car Jack Mechanism:
There were five magnets connected to a thin slab of wood which is placed on the magnetic strip on the wrench to pick it up. This technique was fairly consistent with picking up and depositing the wrench. In addition, this mechanism featured a wooden rod was attached to the slab of wood.
Fuel Crank Mechanism:
The two prongs are at a great angle with each other, which allows the robot to be slightly off course and still turn the wheel the right number of degrees. In other words, it gives the robot a higher margin for error.
