5 FIRST Tech Challenge Basic Bot Guide for REV- Part 2 Game Specific 5 Introduction What is FIRST Tech Challenge? FIRST Tech Challenge is a student-centered program that focuses on giving students a unique and stimulating experience. Each year, teams engage in a new game where they design, build, test, and program autonomous and driver operated robots that must perform a series of tasks. To learn more about FIRST Tech Challenge and other FIRST Programs, visit FIRST Core Values We express the FIRST philosophies of Gracious Professionalism and Coopertition through our Core Values: Discovery: We explore new skills and ideas. Innovation: We use creativity and persistence to solve problems. Impact: We apply what we learn to improve our world. Inclusion: We respect each other and embrace our differences. Teamwork: We are stronger when we work together. Fun: We enjoy and celebrate what we do! NOTICE OF NON-DISCRIMINATION For Inspiration and Recognition of Science and Technology (FIRST ) does not discriminate based on race, color, national origin, sex, disability, age, status as a veteran who served in the military, religion, gender, gender identity, or gender expression in its programs and activities. Keep updated at: Gracious Professionalism FIRST uses this term to describe our programs intent and Gracious Professionalism is not clearly defined for a reason. It has different meanings to everyone. Some possible meanings of Gracious Professionalism include: Gracious attitudes and behaviors are win-win. Gracious folks respect others and let that respect show in their actions. Gracious Professionals make valued contributions in a way that is pleasing to others and to themselves. In the end, Gracious Professionalism is part of everyday life. When professionals use their knowledge graciously and individuals act with integrity and sensitivity, everyone wins, and society benefits. Watch Dr. Woodie Flowers explain Gracious Professionalism in this short video. Gracious Professionalism - Doing your best work while treating others with respect and kindness - It s what makes FIRST, first.

6 6 FIRST Tech Challenge Basic Bot Guide for REV- Part 2 Game Specific Introduction to the Guide Introduction There are multiple versions of the Push Bot. This season the Push Bot is being given a new name - the Basic Bot. The chassis build guide has already been released. This guide contains the instructions to build armature for the Basic Bot chassis. The armature is specific to this year s game. It can capture one or two balls, a silver game element, and deliver them to the lander. It can drive over the crater rim. It is strong enough to lower itself from the lander and lift at the end of the match. With these challenges met, it encourages teams to make it even better. One of the guiding principles of the Push Bot (now Basic Bot) has been to only use parts in the basic kit and to not cut or otherwise modify the parts. With items outside of the kit of parts, a team should be able to modify the collector to capture silver easier or even to capture and score gold elements too! Teams are encouraged to modify the design to deliver team markers and to attach a mechanism that will latch onto the Lander to allow lowering and lifting of the robot. Parts REV FTC Competition Set Electronics Modules and Sensors Set Control & Communication Set 1 or 2 (Optional) Only the tools included in the FTC Competition Set will be needed to build the chassis. The screws and nuts are a standard size and having more tools may allow more students to participate at the same time. (Optional but recommended) A ruler is not needed to build this robot, but it is necessary to make sure that the robot is competition ready. We also specify dimensions for some parts to help prevent interference between various robot components. Tips and Tricks Secure the screws/nuts just enough, so parts do not slide/move relative to each other. Overtightening the screws will damage the aluminum extrusions. Make sure that set screws are installed in every axle collar. Refer to the legend provided in the Kit of Parts, if any parts are unfamiliar. Make sure that all assemblies are square. It is hard to drive a crooked robot straight! The drive wheels are powered by two DC motors, which are relatively heavy. The drive wheels are on the back of the robot, because that is where the most weight is. This weight is needed to help the wheels grip the surface better. Omni wheels are on the front of the robot, which allows the robot to turn more easily. The omni wheels can slide sideways with very little friction due to the rollers. Unless otherwise noted, the top image in each step shows the necessary parts; the lower image shows the completed assembly. Revision 1.2: 09/12/2018

50 50 FIRST Tech Challenge Basic Bot Guide for REV- Part 2 Game Specific Step 41: Complete the Wiring Refer, if necessary, to the instructions in the Chassis Guide for more details on how to wire a DC motor. 1. Plug the left drive motor into port 0 of the motor controller. 2. Plug the right drive motor into port 1 of the motor controller. 3. Plug the arm motor into port 2 of the motor controller. 4. Plug the sweeper motor into port 3 of the motor controller. 5. Plug the servo motor into servo extension wire. 6. Plug the servo extension wire into SERVO port 0 of the motor controller. 7. Connect the motor controller to the robot controller. 8. Connect the motor controller to the switch. 9. Connect the robot controller to the motor controller. 10. Connect the switch to the battery. As always, be careful when wiring, do not allow any wire to catch between two gears or two moving parts of the robot (ex. arm and tower). SECURE ALL WIRING! Use zip ties, plastic covered wire (ex. sandwich bread ties, garbage bag ties, etc.) to secure wire to a channel or other support surfaces. Revision 1.2: 09/12/2018

51 FIRST Tech Challenge Basic Bot Guide for REV- Part 2 Game Specific 51 Final Steps The armature has been built. Programming will be needed to make the robot functional. Testing should be done to determine whether anything needs to be changed or optimized for the season s game rules. It will also show whether more cables need to be secured or re-routed. Numbers and other stickers will be needed to make the robot competition ready Check the game rules for all of the applicable stickers - usually the game rules include a self-inspection check list. USE THIS CHECK LIST BEFORE COMPETITION! Visit the FIRST website for programming instructions and game rules. Special Thanks and Best Wishes FIRST Tech Challenge would like to sincerely thank the creators of this document David and Lydean Spangler. The Spangler s have worked tirelessly over many years and seasons to create, update and improve this document to give teams a how to guide for building the robot chassis to build upon and improve. We are forever grateful for their help and support in this endeavor. David and Lydean would also like to send a special shout out to Jeff Tjiputra, a former Maryland FIRST Tech Challenge Affiliate Partner, for reeling them in: hook, line, and sinker! Or was that hockey pucks, ramps, and rollers! They visited an FIRST Tech Challenge Open House early in the season and took a LEGO Bot. He thought that was a bit humorous. He helped them (and all the Maryland and DC teams) through their first season. He has since retired from the Affiliate Partner position, but he s as hooked as the Spangler s are; he s now a Maryland Judge Advisor and they look forward to seeing him next year. Please direct any questions or comments about this guide to: firsttechchallenge@firstinspires.org and put Questions about the Basic Bot Guide for REV- Part 2 Game Specific in the subject line and we will redirect the s to the appropriate responders.
