My Robot

My physics teacher assigned my class to build a lego mindstorm ev3 (the newest one). To get things rolling, we built a robot that was programmed to move forward and stop a certain distance away from a box. The robot stopped because of its sensors. Then, we programmed it to drop the hook-like thing and move backward with the box in its grasp.

After we successfully completed the building and programming process, we joined forces with other groups for another challenge. We were supposed to simulate a line of cars stopping after the first car stops. We had one robot in front programmed to stop at a certain distance, then we placed the other robots a certain distance behind it. Those robots were programmed to stop 5 cm away from the robot in front of it, but there was a problem. The sensors were not picking up the robot in front of it, so we had to add a makeshift shark tail to the back of each robot. After we added this, the robots were able to sense the shark tail and stop. After we were done with this, we took the robot apart and were given a choice between four different robots to build. We ended up choosing Gyro Boy.

We built Gyro Boy with only minutes to spare before we had to take him apart, but when we put the battery in the ev3 core, it wouldn't turn on. We thought it was because we didn't charge the batteries long enough, but when we were building the robot, it was charging the whole time. Unfortunately, we were unable to actual program Gyro Boy and test him out, but we still had a lot of fun building him! This is what he would have done:

As you can see, Gyro Boy responds to each color differently causing him to do different things when presented a different color. Also, the stand seen in the beginning is used to help Gyro Boy get a sense of balance. Once he becomes balance, the stand is removed.
