Meeting Notes 2008 March 30

We're getting close to finishing the mechanical construction of our first two bots. In previous weeks we'd soldered the motor controllers and started on two BBB's.

Today we:
  • finished the two BBB's we started last time.
  • started and finished another BBB (it's nice to have a spare!)
  • whisker sensors. Was a pain to get the pin with heatshrink into the spring, but it seems like a fantastic sensor design.
  • Selected club officers.
Next week:
  • Put the bots together! Everyone should bring a small box.
  • Start programming

Sequoia Robotics

The Sequoia Robotics Club started a few months ago. Our first project is a simple bot that will move forward until it bumps into something, backs up, turns, and continues on its way. There were a couple of reasons to choose this simple bot as a first project:
  • Demonstrate all the fundamental elements of a bot. By keeping it simple, we can focus on the basics.
  • Give everyone a chance to make mistakes as cheaply as possible. When your learning to solder you are bound to fry a board or two. It's a lot better to fry a $15 board than a board that's part of a $100 kit ...
  • Make members feel comfortable with stuff we've designed ourselves, rather than kits designed by others. I worried that if the first project we worked on was a robot kit from someone else, that we'd be reluctant to put together a design of our own. Better to start with our own right off that bat.
The bot is put together from a few simple components. It wasn't as cheap as I'd like, but well worth the cost for a simple bot that demonstrates all the basics!
We our Solarbotics stuff locally from Hobby Engineering.

I expect that our next bot will be a Solarbotics "sumovore" with an atmel board. We'll see ...
