I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.

Not to mention it's easier servicing sprockets and chain outside of the gearbox.

Second the question that Michael brought up on the side rails.

I'm curious to see how the bearings hold up due to the the larger cantilevered lever arm they are sitting on. If you already calculated out the reactionary forces on the bearings due to the robot weight and deemed it good then disregard!

Chain guards seem to be a plausible way to help the DSC out

We ran the calculations. The axles will be perfectly fine.

Chain on the outside is to free up space on the inside of the robot and easier servicing. We have run belt the past 4 years and so far I am much much happier going back to chain, particularly with the versa bearing blocks and cams

What's the length of the slot you made for tensioning the VersaBlock? Just wondering.

Looking really nice!

Sean demanded the chain be cleaned in a ultrasonic bath so his hipster clothes wont get dirty. Its the only reason we ever did belt.

You know, the worst part is I'm not so sure this is a joke.
