# Programless Drivetrain Activity

## 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

### Curriculum Connections

* Intro to Robotics V2 - Unit 1, Lesson 2: Mechanical Basics
  * This activity can replace or be an additional option to the EDU Launcher Build

### Activity Goals

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.
