Final Assembly of Our Machines (Finally!!!!)

The Ramp:
Our ramp is actually our MCM and also the most complicated modules that we have ever built. It consist of:

a) The Arm - A retractable arm that will drop down at the beginning of a round. Before that, it is hold by a pin.

b) The Bearing System - It consists of a horizontal bearing that slide on two 1/4 inch rods. It also hold The Arm.

c) The Base-plate - The base of our ramp assembly. It also has velcro underneath it so that it will stick on the table of the arena..

d) The Legs - Made from aluminum tube, we made them to have different length so that the elevation angle of the rods for The Bearing System will be the same as the ramp inside the slots.

e) The Winch System - The heart and the engine of of this module. It will pull the bearing up the 2 rods.

The Ramp work with the winch system that has very high torque pull the bearing by using a kevlar thread, up the two elevated rods. When being pulled, the pin that hold The Arm disconnected from The Arm. The inside arm of The Arm drop into balls inside the slot. The winch continue to pull the bearing and this cause The Arm to push the balls into the hole inside the slot.

These are the real picture and the drawing of The Ramp:



The Flipper Pusher:
This is the most problematic module that we have ever made. We try to make this as simple as possible, but we found out that it was impossible. Because of that, we have to redesign the whole module. The final flipper pusher consist of:

a) Flipper Arm - It has racks on it so that the motor can hold it and also push it downward.

b) Flipper Pusher Base - It has planetary gearbox mounted on it. It also has velcro under it so that it will stick on the arena table.

At the beginning, the motor will hold the arm. Then, the motor will release the arm so that it will drop by gravity into the space between the flipper and the ramp inside the slot. Here, the end part of the ramp will push the flipper because of its geometry. Then, the motor will push the arm even deeper so that flipper will be lock and no opponent can push it back.

Here is the picture and the drawing for The Flipper Pusher:

The CarThis is our simplest module. It is just a simple car that can move forward, backward and turn left and also turn right.

Here is the picture and the drawing:



These are the three modules that we have successfully built and we are proud of it. We are really grateful to all that really help us to complete our project. Special thanks to Mark Gordon (our GSI), Prof. A. John Hart (our professor), Michael Umbriac (our lecturer), Bob Coury and John (our Machine Shop Instructors). Thank you.
