CYOCrawler: Open-source quadrupedal robot

Description

Back us on Kickstarter! https://www.kickstarter.com/projects/cyobot/cyocrawler-building-tomorrows-innovators

CYOCrawler, a quarupedal robotic platform by CYOBOT LLC, is the ultimate toolkit for beginner to advanced robotic adventures. The robot comes equipped with enough peripherals for most robotic applications, and extension block to connect further devices if needed. CYOCrawler comes with its own coding interface embedded, allowing seamless onboarding process for beginner, with more than enough project activities to learn and play. It is also open-source (OSHWA US002433), welcoming advanced players to creatively level it up.

The STLs for the robot, the PCB design and source code for built-in coding interface can be found in the official Github repo link of the project (https://github.com/CYOBot/CYOCrawler).

- Speaker
- Microphone
- 33-NeoPixel-LED matrix
- 12-NeoPixel-LED ring
- Micro SD card reader
- USB C battery charger and smart charging/discharging system
- 12-channel servo controller
- Extension block allows you to seamlessly connect additional devices/sensors (with power, I2C, SPI, UART, GPIO)
What's included in a CYOCrawler (Recommended for Beginners):
- CYOBrain
- 8 servo motors
- 3D printed frame
- Comes pre-assembled out of the box
- Embedded Python programming portal
Challenge you to build 1,000 projects

Every week we release challenges on our GitHub & Reddit channel for our community to keep building and learning from each other. Participating in our challenges for a chance to earn a contribution on our official Github repo. We hope to see you there.

Level 1-200: Learn basic Python coding and apply simple algorithm leveraging built-in libraries to write applications such as making the robot walk, dance, play music, and more

Level 200-500 (Available for subscribers): Explore multiple peripherals (sensors, LEDs, motors) to create applications in basic networking, basic cloud computing, IOs

Level 200 (Clock/timer): Write a program that turns CYOCrawler into a Pomodoro timer using buttons to set/start/stop the time, LED matrix to display minutes, LED ring to display seconds (as progression within a minute), speaker to play time's up tune while controlling motors for CYOCrawler to wave/dance when time's up

Level 220 (Distance sensor): Write a program to sense distance to obstacle and change LED color on CYOCrawler using an ultrasonic sensor connected via an extension block and built-in library for ultrasonic sensor.

Level 250 (Flappy Bird): Write a program that runs a Flappy Bird-like game on CYOCrawler using buttons for jumping, LED matrix to display game and speaker to play sound effects.

Level 500-800 (Available for subscribers): Feature complex algorithms, real-time embedded with C/C++ programming to write applications in control system, kinematics, computer vision, sensor mesh, beginner AI/ML

Level 800-1,000 (Available for subscribers): Complete design project with extended peripherals to do interactive standalone applications leveraging all capabilities of the robot

For beginner learners that need support to get started easier, we have:

Extensive learning library with robust challenges and instructions to support your exploration
