Overview

Objectives/Goals I. Purpose: Can a rover simulator consistently climb over objects that are as big as it self. II. Hypothesis: I predict that 75% of the time, the rover simulator can climb an object equivalent to its own size. (Rover) Methods/Materials III. Methods and Materials: Light weight wheels, three motors (8 AA batteries), and a variety of K#nex pieces. Methods: Design 1: The body was too long and when it tried to climb it got stuck on the top of an object. Design 2: I took a shorter piece of K'nex and it would climb very well but it would sometimes have a hard time. Design 3: I attached two more motors to the rover but it could not climb because the design of two motors on one set of wheels was not working together. Design 4: I tried moving the motors from being one in the front to one in the middle and one in the back. This is the design that worked best. Design 5: I tried the first motor in low gear so all three motors were in the same gear. Design 6: I tried to move the wheels into different positions on the rover. It did not work. In the end I decided to work with design 4. Results I have come to the conclusion that my rover can successfully climb rocks that are as tall as its own size (6in) 80% of the time. As the rock size increases the success rate decreases slightly with the exception of
