 Initial Design: We wanted to create a robot that would perform the following fuctions -move (straight, stop, turns) -pick up and drop off the mass -sense light/darkness

Day 1 Leah and Jovan both worked on building the robot. We knew we would need light sensors, gears to provide a force advantage (attached to a pulley with string), and two wheels for general movement.

Day 2 Jovan built the robot while Leah had to restart the program because the program she wrote on Day 1 was erased. We organized the program using MyBlocks because otherwise it would freeze.

Day 3 Jovan continued building while Leah finished the program. We rebuilt our entire robot, seeing that the general design ended up being unstable and angled. Even with the help of a counterweight to balance its forward torque, we had no luck maintaining stability. We knew our focus for our next design would be building the majority of the robot directly above the center of mass (in between the wheels and where the brick lay.

Day 4 We changed the robot in order to make the lever arm (with the motor/gears/string attached) farther away from the center of mass so that it would clear the distance between the double black and drop off bin. We changed the program to accommodate this change, by erasing the "go" for 1 second block that we needed before. This change forced us to use a counterweight, though.
