1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.

2. A robot must obey orders given it by human beings except where such orders would conflict with the First Law.

3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

What's easy for humans is hard for robots

• Science ABC - What is Moravec's paradox

• TED - Why don't we have better robots yet?

British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law is the best known and most widely cited. They are part of his ideas in his extensive writings about the future.

The laws are:

1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.

2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible.

3. Any sufficiently advanced technology is indistinguishable from magic.

Think about Robotics and especially the advancement of AI since November 30, 2022. How do the advancements of technology really validate Clarke's 3rd law?

What technologies do you use regularly that you use purely off of faith that they'll work, knowing none of the actual science behind the technology?

Complete the Driving Configuration Activity

Additionally, if you're using a typical drivetrain, you can specify it in the device setup and use drivetrain commands that make moving a little easier - especially when adding a controller.

Practice:

• Using VEX V5 Code, figure out how to add motors to a blank-slate robot.

  • Add Motor --> Port 1 --> Name it leftMotor

  • Add Motor --> Port 10 --> Name it rightMotor --> Reverse its direction

• Add code to make the robot

  • Move forward a certain distance using both motors

    • Notice, the distance you move forward. How far do you move forward if your motors move 360 degrees? --> roughly 12"

    • The reason: The diameter of the wheels is 4". Equation for circumference = 2*Pi*r. 2r = diameter. 4"*PI = 12.56" (just over the 12")

  • Turn using the Swing turn technique (1 motor spins forward, the other motor doesn't move)

  • Turn using the Point turn technique (both motors spin in opposite directions)

The engineering journal (which I'll occasionally refer to as your "digital notebook", "engineering notebook", or "digital journal") is a vital part of the Robotics Course - A way to document what you're doing throughout the semester. 

Engineering Notebook Unit Overview 

DO NOT FOLLOW THESE INSTRUCTIONS FOR END OF YEAR GAME

We're playing Hungry Hungry Hippos - Robot Style (Robot soccer with 4 goal zones)

• Read and take notes in your engineering notebook: Passive Manipulators (Just the part on plows)

  • What makes a manipulator "passive"?

  • What is an advantage of a passive manipulator?

  • Give a real-world example of a passive manipulator.

  • Sketch in your engineering notebook (sketch on paper then take a picture and upload) a passive 

Starting Rules

• You must start with an unmodified speedbot (no claw, no motor changes, no special anything). Point deduction if you did not follow the speedbot instructions properly.

• You may add 1 passive manipulator (plow, scoop, or other device that allows you to direct the game elements), but no motors can control the passive manipulator (opening/closing, raising/lowering, etc) - otherwise it's not passive.

  • Your manipulator must be documented in your engineering notebook prior to installation - what is it you're trying to add?

• You may not bend or cut anything without first receiving permission from Mr. Birkel.

  • Any team that violates this gets a point penalty or has to pay for the damaged part.

  • Many parts exist that are already cut and bent. Lets check to see if something exists prior to potentially ruining existing material.

Hungry Hippos Gameplay

• The field has 4 goals, 1 in each corner. 

  • Teams should not enter these goal zones (as much as possible). 

  • Opposing teams are not allowed to remove scored balls from scored zones. If an opposing team removes a team's scored balls, they will be returned.

  • Teams that remove their own scored balls from the goal (intentionally or not) lose those balls and they're now available for anyone to try to score.

• Teams have 60 seconds to score as may balls into their goal zone as possible.

  • Balls remaining on the field, unscored do not count towards anyone's points.

• The "Play" and "Rethink" sections cover the material using 3 different programming languages. You don't need to cover all 3 languages. Pick the programming language your group wants to use (Blocks, C++, or Python) and cover the material for that language.

*** Updating the journal should be a balanced effort for all students. If 1 person is doing the majority of the updating, the other students will lose points.

See the "Motors" section in the Speedbot unit. It's important to remember that V5 smart motors are sensors as well due to the fact that they not only put out information (speed, rotation), but they also sense information (See the "Sensing" column in the "Motors" section).

Students will learn

Students will learn the purpose of an inertial sensor and its practical application.

What is the Inertial Sensor?

Allows you to track headings (Degrees of rotation) using a built-in gyro - tracks the robot's rotations around an x, y, and z axis.

VEX Library - Using the V5 Inertial Sensor

Heading vs. Rotation

• Heading: a +value between 0 and 359.99. 

  • If a robot is @ 350 degrees and they rotate right 10 degrees, they're at 0, not 360.

• Rotation: A value representing the heading as a + or - degree not limited to the same 0-359.99 values. 

  • If a robot is @ 350 degrees and they rotate right 10 degrees, they're at 360, not 0.

% operator (Modulus/Modulo)

The % operator is used like division (/), but instead of calculating the division answer, it calculates what's left when you divide.

Example: 

• 19 / 2 = 9.5 = 9 + 1/2 = 9R1 (9 remainder of 1)

• 19 % 2 = 1 (because there was 1 leftover)

• 19 / 4 = 4.75 = 4 + 3/4 = 4R3 (4 remainder of 3)

• 19 % 4 = 3 (because there was 3 leftover)

When dealing with 360 degrees of rotation, the % operator can be used to show that 365 Degree rotation is the same as 5 Degree heading

• 365 / 360 = 1.013888... = 1+5/360 = 1R5

• 365 (rotation) % 360 (degrees) = 5 (heading)

Python Functions: 

• calibrate_drivetrain() - set's the robot's x, y, z rotation to match the current position of the robot and position of the sensor.

• set_heading(#, DEGREES) - reset's the robot's orientation - advised to set initial position to 0 degrees most of the time. Angles are limited to 0-359.99

• set_rotation(#, DEGREES) - reset's the robot's orientation - advised to set initial position to 0 degrees most of the time. Angles are not limited to 0-359.99

• turn_to_heading(#, DEGREES, [wait]) - turn to a specific heading between 0 & 359.99

• turn_to_rotation(#, DEGREES, [wait]) - Similar to turn_to_heading, but allows values less than 0 and greater than 359.99

• drivetrain.heading(DEGREES) - tells you the current heading of the robot.

• drivetrain.rotation(DEGREES) - tells you the current rotation of the robot.

Vex Library - Using the V5 Distance Sensor

VEX Library - Coding the V5 Distance Sensor using Math Inequalities

This sensor replaces the previous VEX UltraSonic sensor. 

• The ultrasonic sensor would send out a high pitch sound (higher than human ears can detect) which would bounce off of objects, return to the sensor, and the time interval would determine how far away an object was. This was useful, but because sound is a wave, the further the sound traveled from the robot, the wider an area it would travel and detected objects might not be directly in front of the robot. The closer an object is, the more likely it is to be directly in front of the robot.

• The V5 Distance Sensor uses a lazer instead of a sound. Because the lazer is a focused light beam, it doesn't spread out like sound does and more accurately determines if objects are directly in front of the robot.
