Creating an openSUSE powered Robot
- 1. Simon Lees sflees@suse.de http://simotek.net Lets make a Robot openSUSE Style
- 2. About Me • I have been working for SUSE for 1 year • Previously worked for a Radio Comms company • Maintainer of Enlightenment on openSUSE for 5+ years.
- 3. Its a Trap!!! Run away now.
- 4. Why make a robot? • Because I can • The world needs more cool Robots
- 5. Why use Linux? • Text to speach - speach to test • Wifi • Video streaming • Easy to develop
- 6. Downside to Linux • Doing “Real Time” operations and working with GPIO can be annoying. • Solution: Use an Arduino and talk via serial – Lifes simple that way.
- 7. Hardware is hard • I needed something off the shelf • I wanted tank something with tank tracks – there wasn’t anything under $1000 that was good. • Was going to use an RC Car
- 8. Design
- 9. Electronics isn’t easy 1)Providing power 2)Controlling the motor 3)Converting 12v to 5v to run the Processor
- 10. Choosing a Processor • ODroid C1 ‒ Not a great choice • Get a Serial Cable • Arduino ‒ Alamode ‒ Sits on GPIO ‒ Powered from ODroid/RPI
- 11. Staging the build 1) Get a processor and make it work 2) Have enough software to drive a motor 3) Get a chassis 4) Get a battery 5) TBD a)Video streaming b)GPS and Compass c)Better UI d)Skynet

- 21. Demo
- 22. Summary
- 23. Summary • The joy of open source, by taking a bunch of things done by different people and gluing them together you can make something cool without much effort. • Modular designs with common protocols are good. • Use the right tools for the job (or close enough anyway) • Build yourself a Robot, theres kits for just about any skill level.
