For this project we created a robot that could cross a 6 inch gap without any human help. This was done under a 45 minute time constraint, therefore there is room for improvement in the design that would increase the robots ability to cross gaps.

      The final in class design consisted of an EV3 brick attached to two large motors extending from the front and the back of the brick. These motors each had two large wheels attached for movement. The structure is held together by a series of straight long lego pieces under the brick which connect to the two motors. These long pieces keep the two motors stable so they do not get displaced when the robot is moving. The motors are run at full power, one spinning clockwise and the other spinning counterclockwise due to the placement of the motors, in order to maximize the speed of the robot. The thought process is that the less time the robot spends trying to cross the gap the less likely it will fall. 

    This current design is able to clear the 6 inch gap and a bit more, however, after that it begins to tip into the gap. Some modifications that could have been made if there was more time would be to copy the design of the front motor to the back in order to increase the length of the robot. This would allow it to cross longer gaps since it has more weight distribution meaning it has more time before it starts to tip into the gap. Another improvement that could be made is putting some small lego pieces under the stablilizing long pieces in order to have it bend less under the weight of the brick. A third improvement that would help is make more connections between the long stabilizing lego bricks in order to make sure that it will stay together under more tension.
