Hello everyone!!! I'm back with an epic last minute post to the Community Olympic Building Challenge. This is EV3 Olympic Swimmer. It has two arm that act almost like real arm going around and around. On the back, I made a kicking mechanism witch is very effective. Plus it looks like read legs. The Brick is in the center to balance out the weight. I use a ship base from set Coast Guard Patrol - 60014. Sadly, I had to put 2 water bottles on each side and one in the front because of the weight of the brick, motors, and parts. Its also keeps the ship stable so that its would tip. The program is very simple, only 25 blocks in fact. All the motors do is spin. But the arm rotations are set to slow down so that it wont splash the brick or motors. If the ultrasonic sensor sees a object twenty inches in front of it, the program will shut off. If you press any of the outer brick button the movements will begin sounds "FanFare," and "Cheering," will be played. When the center is press the program will play sounds "FanFare," and "Cheering," then stop. WARNING!!! This is risky project that beginner or intermediate skill level should not attempt because of the high chance your brick could get wet and be ruined. Thanks for viewing and please feel free to check out all my other posts! Good bye until NeXT time! P.S. I will get a video at a pool soon so be looking for a video in about a few days!
