Here is our video explaining how the Anti-Virus Protocol saved our robot, Kado.

The Anti-Virus Protocol starts with a PUSH of a straw into the toy truck. The kinetic energy of the rolling truck transfers into the dominoes which are standing at potential energy. The energy moves from domino to domino and eventually pushes the ball off the end of the platform. The rolls down the incline plane into the shaft.

At the bottom of the shaft is a button. Gravity pulls the ball down the shaft and onto the button activating the electric motor of the conveyor belt.

Electricity powers the motor which turns the gears which move the conveyor belt. On top of the conveyor belt are marbles with potential energy. As they move to the end of the conveyor belt, gravity pulls them down a shaft and into a cup.

The cup is attached to the pulley system. As the mass in the cup increases, the cup moves down pulling the cardboard wall up releasing a ball.

When the ball is released, it rolls down the incline plane transferring its kinetic energy into the virus at the end of the ramp. This kinetic energy causes the virus block to fall over in defeat.

Below is a picture of our entire Anti-Virus Protocol. We did use light energy so it is easier to see inside the robot.

Here is the Anti-Virus Protocol in ACTION – Ready, Set, Go!

We used the following materials in the construction of Kado and his Anti-Virus Protocol: cardboard box, aluminum foil, scrap pieces of foam rubber, PVC pipe, plastic straw, toy truck, dominoes, 2 rubber balls, duct tape, clear tape, VEX IQ robot brain and pieces, marbles, plastic cups, paper cups, rope, pulley, markers for hand-drawn virus
