Code Kitty Robot v2.2

thingiverse

Introducing the Code Kitty version 2! ============================ The Code Kitty robot is a 3D printed robot designed to teach kids coding, engineering, and robotics. We developed it because we wanted every kid to have access to a cheap robot that could help them learn the joy of coding, engineering, and robotics! We offer the robot to our workshop participants or sell complete kits under a "buy one/give one" program for $50. Although the 3D printed parts are the same, there are two "builds" of the electronics: The "Workshop Build" and the "DIY Build". You will need to print one base, one face, one tail, two rings, two wheels, and two hubcaps. We recommend combining all the parts that you want to be the same color into one print job, and the parts are small enough that the entire robot can be printed in two print jobs on most 3D printers. The "Workshop Build" ------------------------- This build of the Code Kitty robot is used in our hands-on workshops to teach coding, computational thinking, and engineering skills. It features the 3D printed parts with the following components: * Adafruit Trinket m0 * SG90-compatible 360 degree rotational micro servos for the wheels * Two regular size rubber bands for the wheels * Our custom Code Kitty Breakout Board seated on the pins of the Trinket m0 * A 3 cell AAA battery holder * Four AA batteries * A standard-size marble - 14mm * Optional 3-pin sensor modules such as infrared object avoidance, light sensor, etc. * Ribbon cable for sensor module Build instructions, software, and coding instructions can be found at http://codekitty.org. The "DIY Build" ----------------- If you don't have our custom Breakout Board or want to Do It Yourself (yay!), you will need all the parts listed under "Hardware", except for the Breakout Board, along with the following: * 400 point "mini" breadboard * Piezo buzzer for speaker Connect the pins on your Trinket m0 as follows: D3 : Speaker + A1: Right servo (signal/orange) A2: Left servo (signal/orange) A0: Touch input - connect a wire or leave bare :) A4: Sensor VCC Bat: Connect to + rail on breadboard USB: Connect to + rail on breadboard GND: Connect to - rail in breadboard Servos: Connect the Orange wires on your servos as listed above (pins A1/A2 for right/left) Connect the Red wires on your servos to the + rail on the breadboard Connect the Brown wires on your servos to the + rail on the breadboard Speaker: Connect the + pin on your speaker as listed above (D3) Connect the - pin on your speaker to the - rail on the breadboard Sensor: Connect the OUT pin on your sensor to the + rail on the breadboard Connect the GND pin on your sensor to the - rail on the breadboard Connect the VCC pin on your sensor to the as listed above (A4) After wiring this up, connect your battery pack to the + rail on the breadboard and use the power switch on the battery pack to turn your robot on and off. Note that the power switch is overridden and the Trinket still powers on when USB is connected. Finally, please connect with us on Facebook and Twitter and post your Makes if you make our kitty! Happy Making!
