"Hi! This was our final competition robot product. It took us 8 months to build. We put a lot of hard work and dedication to get it done. I hope you enjoy our video.(next scene)This year our strategy was to stack yellow cones on a mobile goal and take the mobile goal holder to the 20 point zone. Each yellow cone stacked is worth 2 points."
"There were several components of our finished product. There’s a 4-bar mobile goal holder, chassis, arm 4 bar linkage, turntable, claw, sensors for the autonomous, and lots of wiring. They all play a different part in the process of the scoring points."
"It’s a 4-bar linkage. Our arm contains two 120 tooth high strength gears and in between those is a 12 tooth metal gear. We chose the small metal gear because it gives it more torque when there’s 2 bigger gears on the outside. It moves up and down far enough so it can reach the top of the mobile goal. Mobile goal holder is also a 4 bar linkage, it helps by picking up mobile goals and placing them in the 5, 10, and 20 point zones."
The turntable helps the arm rotate to make room for the mobile goal holder. We rotate it CW and CCW so the arm and claw can pick up cones in the back of the robot instead of rotating the whole thing. This gives us an advantage because it reduces the amount of time it takes to pick up cones. This allows us to score more points, too. The more time efficient it is, the more time we have to pick up even more cones which leads to more points.
The way the claw works is that it sucks in the cone. It sucks the cone because the gears go to the opposite way of each other. It turns clockwise and counter-clockwise. It can rotate more than 360 degrees at once. It helps pick up the cones so it can be placed on the mobile goal. The claw, arm, and turntable all work together to get more points by stacking more cones onto the mobile goal.
"The chassis is an important component of the robot because it is the base of the robot which everything is placed on. It has 4 wheels and a gear train. It allows the robot to move around on the field. It is a basic H-drive chassis. On our scale drawing, it demonstrates how you need 4 congruent length C-channels for both sides of the chassis. It also shows the lengths of the middle pieces of the H-drive. It also has support pieces on the bottom of the robot. You will only need this if you have a lot of heavy components on the top."
