Dave Cline's Blog

I received an email from “someone” claiming that they found my books on facebook, and my goodreads entries and offered to post the books on their facebook page.

Hello Dave, I came across your page on Facebook and then checked through your book on Goodreads. Since it hasn’t received much engagement yet, I’d be happy to share your book’s link or cover on my Facebook page to help introduce it to more readers.

Married 33 years ago today.

We’re out at Lincoln City, Oregon. A dreary, stay inside, next to the fireplace kind of day.

Surprised her with her favorite flowers…

How to make a spherical robot, with three degrees of freedom, tumble in a straight line due to center of gravity displacement?

To continue are State Machine discussion…

GOAL: Goal objective exists? (Move!)NAV: Navigation objective exists? (Forward!)SYS: System objective exists and is amenable to bot movement? (Plenty of battery!)OO: Orientation objective exists?Current OO?Roll X:Forward 1 revolution.

In order to accomplish this…

Current BO: Bot orientation (where we are now, angle ...

Overview

These will be notes I write to myself regarding the software necessary to program the navigation, movement, observation, orientation and battery charge control of this tumbling robotic rover.

I’ll be building a state machine that represents command & control of the bot. If you’re not familiar with a state machine it’s essentially a flow chart. The flow between the ovals (conditions / modalities), squares (commands / directives) and diamonds (decisions / choices) represent, as a whole, a...

Here will be the anchor site for my research and testing while building (or attempting to build) the BumbleBot tumbling rover.
