What is Lolibot?

• Lolibot is a ping pong soccer playing robot.
• The brain is a lolin32-lite.
• It has two wheels.
• There is a 6 axis accelerometer.
• There is a small servo to kick the ball.
• Last but not least, It has an IR sensor to detect if there is a ball in place.

Open Hardware Mini-Conf

• 9th consecutive year
• Started out as the Arduino Miniconf
• Design a custom board each year that has a soldering component, some simple software and is using a bit of tech that is new or interesting.

Design Timeline for OHMC

1. January - Previous conference happens. High on success we throw around fantastic ideas about what we'll do next year
2. Mayish - Call for papers comes out. We email each other.  Nothing really happens.
3. Julyish - Deadline for papers is in a few days.  We actually meet up and someone has an idea.
   We relax.  A Decision Has Been Made.
4. September - Someone remembers that we have to actually design and prototype said idea.
5. October - First spin of the hardware.  It doesn't work.
6. November - Second spin of hardware. It (mostly) works.
7. December - Cut off for ordering components and boards.
8. Early January - Frantically fix and patch the bits that don't work. Write code. Panic.  Panic some more.  Pit of despair.
9. Late January - Successful event! A grand time is had by all.  What a rewarding experience.  GOTO 1

This year's Design Decisions

• ESP32 chips are still great.
• There are many dev boards available.
• Stop. Shaving. Yaks.
• People like the opportunity to do some some soldering.
• Simplier hardware means better opportunity for software.

Goldplating that stuck

• Expansion headers.
   
• IR sensor.
   
• APA106 LED's

Goldplating that didn't stick

• Remote control with eBadge.
   
• Boost converter to up the speed of the wheels.
   
• Loliwrapper - Design was complete, but missed manufacturing deadline.

Control and Software

• MicroPython is getting quite mature.
• Building on software stacks that our team were already using.
• mqtt is good for rapid prototyping (lets see how it holds up with 40+ people using it)
• Bluetooth on the ESP32 is still a little flaky.

Games vs Real Life

• Circuits actually do something...
• ... But you may not know exactly what until they arrive.
• Chemicals!
• Actual circuit to love and to hold
• Can show off to a whole room of soon to be friends!

• Rate yourself against your friends.
• Virtual Circuits are cheap Circuits
• Built in Solitaire game, so you can get fired from your fake in-game job for spending
  too much time playing
  games...

• OpenSource and fairly mature
• Free (as in beer and speech)
• Just as many quirks as every other CAD tool. (OK, if we're honest, every release you really need to check your pin footprints...)

AutoChanger

<Still no logos, damnit>

What is it?

• When knitting certain types of multi-colour, a manual device switches between them.

• We can make something that moves on it's own at least!

Braiiiiins

• Prototype 1 - Arduino Uno with Servo Shield.
   
• Prototype 2 - Custom Board, Arduino Uno compatible.
   
• Prototype 3 - Custom Board, headers to fit an Arduino Nano

Mechanical Bits

• Designed in SketchUp

• Multiple Iterations (3+)
