Introduction

In this activity, student groups will build a simple drivetrain powered by a single servo and the SRS Programmer. This slow moving drivetrain is intended to offer an opportunity to explore the EDU Kit V2, using the parts to create motion without any programming set up.

Here the focus is on growing more comfortable with the DUO System’s parts, hardware, and tools before tackling larger builds!

Covered Concepts

• Servo usage

• Changing modes with the SRS Programmer

• Simple gear trains

• Using the DUO Build System

• Intro to Robotics V2 - Unit 1, Lesson 2: Mechanical Basics

  • This activity can replace or be an additional option to the EDU Launcher Build

Students will:

• Practice working with the DUO Build System to construct a simple drivetrain.

• Review the tools available within the EDU Kit V2 and utilize them in the appropriate use case

• Explore the basics of creating motion using wheels, gears, and hex shafts powered by a single servo.

Introduction

This activity is intended to provide additional practice with using the touch sensor by completing a simple task. Students will build a small servo “gate” regulating the entrance into an area. To raise the gate, the touch sensor must be pressed, but once a max number is pressed no more entries will be allowed.

Consider pairing this activity with students building a diorama of their gated area. Examples might include a museum, lunch room, theater, or store. This lesson may also be tied with classes introducing CAD, or safety and accessibility standards for buildings.

Covered Concepts

• Touch Sensor

• If/Else logic

• Loops

• ElapsedTime

• Servo usage

• Programming angular limits on a servo with the SRS Programmer

• Intro to Robotics V2 - Unit 4, Lesson 25

• Intro to Robotics V2 - Unit 5, Lesson 29 (ElapsedTime)

Students will:

• Utilize the touch sensor in a practical scenario mimicking a real-life use case

• Practice programming a touch sensor

• Create a program that uses a count to track how many times the touch sensor has been pressed and that uses a timer to reset once the max is reached

Introduction

This activity pairs with the Programless Drivetrain Build Activity to introduce the challenge of utilizing gears to modify the drivetrain’s speed and torque. Students will have to adjust their gearing to accomplish their goal as the servo’s output cannot be modified!

Students will take advantage of the extrusion frame to slide their hex shafts, wheels, servo, and gears into different places to adjust their gearing. Additional hex shafts can be added to expand the gear train.

This activity includes two challenge options: a short version (SV) and a longer version (LV)

Covered Concepts

• Servo usage

• Changing modes using the SRS Programmer

• Calculating the gear ratio of a gear train

• Torque vs. speed in a gear train

• [Optional] Compound gearing

• Intro to Robotics V2 - Unit 2

  • This activity can replace or be completed in additional to the existing Unit 2 Challenge

Students will:

• Explore how changing gearing changes the outputted speed and torque

• Define what is a gear train and gear ratio

• Calculate gear ratios on a gear train

Introduction

This activity is intended to offer a fun challenge of building a robot to play tag against other robots using the touch sensor! Students will build the basic drivetrain, adding a servo for their flag, then program the touch sensor to prevent movement for a few seconds upon being pressed. While disabled from being tagged, their flag will raise as a visual cue of both being tempted and when they’ll be able to move again.

The game can be played using only the base drivetrain OR students may be granted time to build upon their robot using parts from their kit and craft materials.

Covered Concepts

• Touch Sensor

• If/Else logic

• ElapsedTime

• Servo usage

• Programming angular limits on a servo with the SRS Programmer

• Drivetrains

• TeleOp Control

• Intro to Robotics V2 - Unit 3 (Drivetrains and TeleOp Control)

• Intro to Robotics V2 - Unit 4, Lesson 25 (Touch Sensor)

• Intro to Robotics V2 - Unit 5, Lesson 29 (ElapsedTime)

Students will:

• Program their touch sensor to deactivate driving for a time period and raise a servo-powered flag when pressed.

• Practice controlling a robot using TeleOp controls using tank, arcade, or split arcade drive.
