What is a robot

What is a Robot?

  • Sense–takes in information about its environment

  • Plan –uses that information to make a decision

  • Act –has moving parts to carry out commands

Functions

Bricks, Beams, & Plates: Provide stability and support

Gears, Belts, Axles, & Pulleys: Transmit mechanical energy

Bushings: Hold structural parts in place; can also be used as part of a pulley system

Pegs and Joints: Join structural parts together

Sensors: Detect changes in the environment

NXT (Brain): Contains the source of energy for the bot (batteries)

Now it’s time to build your bot!


If your wheel makes one rotation how far will it travel

If your wheel makes one rotation, how far will it travel?

Distance Traveled = Circumference * Rotations


Circle math for movement

Circle Math for Movement

  • What is a radius of a circle?

  • 2. What is a diameter of a circle?

  • 3. What is the formula for the circumference of a circle?

The distance from the center to the outside of a circle. Measure to the nearest tenth of a centimeter.

Measure to the nearest

tenth of a centimeter

The distance, through a circle’s center, from one edge to another.

Measure to the nearest

tenth of a centimeter

Circumference = diameter * π

Π or Pi = 3.14

Circle Math In Action

If your wheel’s circumference is 6.91 and it completes 2 rotations, then it should travel 13.82 cm.Climbing the Learning LadderWhat are some variables which would prevent the Robot from traveling exactly 13.82 cm?

Welcome to the programming environment. NXT G is a icon based user friendly drag and drop program.


Mingo county shewey science academy nxt training

If you have multiple NXT robots in your classroom, a best practice is to have students personalize their robot by giving it a name that is saved in the robot’s brain.


Math applications

Math Applications

  • Metric conversions

  • Setting up equations

  • Perimeter

  • Circumference

  • Collecting and representing data

  • Estimation

  • Problem Solving: making predictions & experimenting


4 20 13

  • Objectives-

    • Use the scientific process to solve the Green City Challenges.

    • Complete two green city challenges:

      • 1 that requires a “push” from the robot

      • 1 that requires your robot to “lift” something


Best practices

Best Practices:

  • Assigning roles: i.e.- mechanical engineer, computer engineer, mathematician

  • Following the scientific process

  • Data Logging

  • Organization: Challenge kids to keep kits organized!

  • Lego League Core Values

  • Awards


Scientific process

Scientific Process:

  • Know the challenge

  • Predict what your robot will do to solve the challenge

  • Experiment

  • Evaluate results

  • Make changes due to inconsistencies in the prediction

  • Experiment

  • Repeat


Data logging example

Data Logging Example

Challenge: Move in a square

BehaviorProgramming

Robot will move forward 8 in.

Robot will execute a point turn by turning off left wheel and allowing the right wheel to move

Robot will repeat steps above 3 more times.

Forward move block, 2 rotations

Forward move block with C motor turned off, 1 rotation

Use Loop Function

Trouble shooting

Trouble Shooting

  • Emphasize that the robots must begin on the designated tire outlines

  • Charge robots each day after students leave

  • Programming Issues:

    • Ensure the arm or wheel is connected to the correct port

    • That the student is downloading the correct program

    • That all pieces of the robot fit tightly

    • That the battery life of the robot is fully charged or close to it.
