Page 29: Configure The Transmitter
Configure the Transmitter You now configure the Transmitter to reverse the directional controls on channel 1. See the VEX Inventor's Guide for detailed information on configuring the transmitter. Turn on the Transmitter. Check the voltage. If the voltage is less than 8.9 volts, recharge the batteries in the transmitter. Press and hold the MODE and SELECT buttons simultaneously until the CONFIG menu is displayed. - Page 30 Press the DATA INPUT minus key once. The arrow should display next to REV (below CH on the display). Press and hold the MODE and SELECT buttons simultaneously until the voltage is displayed. Turn on the Microcontroller and go for a drive! Autodesk's VEX Robotics Unit 1: Introduction to VEX and Robotics...
- Page 31 Amaze Phase Overview In this phase, students test their first VEX robot, Tumbler. Phase Objectives After completing this phase, you will be able to: Test and demonstrate a VEX robot. Identify the basic components of a VEX robot. Prerequisites and Resources Before starting this phase, you must have: Completed all sections in the Unit 1: Introduction to VEX and Robotics up to the Amaze phase.
- Page 32 Evaluation Tumbler Challenge In this challenge, you set up a basic obstacle course to test drive the Tumbler. You learn to drive a VEX robot, while discovering some of the neat features that Tumbler showcases. Challenge Instructions Choose any two “obstacles” available to you in your classroom. These obstacles act as pylons for the robot to navigate around.
- Page 33 Engineering Notebook In your engineering notebook, record a journal entry describing your experiences with the Tumbler robot. Now that you have gotten a taste of the VEX Robotics Design System, brainstorm a list of robots you would like to create.
