#35 chain on a robot is a good thing, in some cases, it just depends on how it is used in the drive-train or any part of the robot for that matter.

We have had cases where #25 chain has broken.

For example we used #35 chain in 2004 to connect the transmission to the back wheels and we then used #25 chain to connect the back wheels to the front wheels in the skid steer configuration.
We had a case in a 2004 practice match where the #25 chain broke, our robot still had three wheels driven, instead of four, but we still made it up the 6'' platform.

Now if the #35 chain would have been replaced with #25 chain, it may have broken causing us to have two wheel drive and that equals no go!

Give Arefin a break about the square edges, did anyone ever think he may be designing the tool path for the CNC to follow, or maybe he is just trying to save some time? Drawings don't have to be perfect, he is just trying to get his idea out there.

Anything under 14fps (calculated free speed) should be good, the control of the robot also depends on the drive train type not just the speed, along with many other factors.

The calculated free speeds for our 2005 robot with only 2 CIMS powering the whole drive train is 4fps in low and 12fps in high using 5,342RPM as the free speed.

The 8 tooth #35 sprocket may work, it depends on how big the sprocket is that he is planning on using the chain to connect to, along with many other things.

I would keep the plates 1/4'' thick, anything much thinner does not allow for easy bearing/bushing mounting. Thicker plates also make the transmission more rigid.

Keep at it and I am sure that you're transmission placed on a robot will be able to move something out of the way!
