Go to Post Woodie once said he wanted to make our brains hurt. And I *don't* think he was talking about getting beaned by 198 grams of foam.... - Ken Patton [more]

How well do the MA3 encoders work?
We have used them for competition and on these dome bots with no issues. We were very pleased with their repeatability.

How do you connect the sensor to your mechanical component? Could you be slipping? That's what it sounds like to me.

We always use these.

Clearly that isn't an issue with all four wheels chained together in this fashion
This bot has two wheels at each end linked for steering and two wheels on opposite sides linked for drive.

We have one MA3 encoder on each steering axis.....the encoder is linked via helical beam coupling to a 1/4" shaft that is keyed to an idler sprocket.

And we all know that because something is "easyer" it is better, right?
You've clearly put a lot of thought into the debate between a "macanum" drive and a coaxial swerve -- right?

Perhaps you'd like to show us your pro/con list for each? Of course, this list includes only quantitative engineering based arguments, right?

This is an engineering competition. Do some.

Re: pic: Revolution Swerve Demo Robot

I like these little systems. FIRST should take note of their flexibility and performance for the price.

Nice robot
