Unit 1
This is the most creative step in the engineering design process.
What is Brainstorming?
What is the Binary System?
An electric motor is useful because it turns electricity into this form of energy.
What is Mechanical Energy?
This allows for a robot to successfully interact in its environment.
What are Sensors?
This type of motion has 3 translational and 3 rotational degrees of freedom.
What is three dimensional motion?
What is motion in the real world?
During this stage of the engineering design process, you weigh the pros and cons of the ideas you had brainstormed.
What is Analysis?
The coding language we use is called "C Language" and within this coding language there are reserved words that cannot be used as a new variable you create.
Each Reserved word you name gives you 50 points.
What is:
Wait, IF, WHILE, FOR, etc...
The strength of the battery's charge is measure in this.
What is Voltage?
This type of loop system includes feedback to the systems program.
What is a Closed-Loop System?
This type of motion has 2 translational and 1 rotational.
What is two dimensional motion?
What is motion in a flat plane?
The name of this is defined by the outside measurement of the threaded portion of the screw.
What is Major Diameter?
This is the process of calculating current position of some moving object by using a previously determined position, or fix, and then incorporating estimates of speed, heading direction, and course over elapsed time
What is Dead Reckoning?
This is a rechargeable WET CELL battery.
What is Lead-Acid?
A garage door is an example of this type of sensor.
What is limit switch?
This formula is used to calculated a twisting force or rotational force.
Gain an additional 50 points by saying what the twisting force is called.
What is T = force*distance?
What is torque?
These signals travel at the speed of light and are created when electrical impulses are sent through the atmosphere at a specific frequency.
What is Electromagnetic Waves?
This command allows you to execute a section of code until a condition is met.
What is while() loop?
This is where the fulcrum is located on a gear.
What is the center of the gear?
This sensor is designed to operate about 1/8" to 1/4" above the line, parallel to the floor.
What is the line following sensor?
A robotic arm is a form of this and it coverts electrical energy into kinetic energy.
What is an Actuator?
Double Points
This is the proper order in which the wires for the motor are plugged into the controller.
(Starting at which wire color is closest to where the Vex Key is plugged in)
What is Red then Black?
Double Points
This force is always directed opposite the object’s motion be it linear or rotational
(Might be part of unit 3)
What is Friction?
This is known as the change in velocity divided by the time it took.
What is Acceleration?
The bumper switches and limit switches can be either of 2 things.
What is on or off?
What is Open or closed?
What is 1 or 0?
The condition where the sum of the torques is zero and the sum of the (linear) forces is zero
What is Equilibrium?
