Hello good day I would like to know how do you set up your double-acting piston that only has an air outlet on one side, do you still use the double-acting selenoid or do you use a single-action selenoid? Without further ado, I bid you farewell and send you my cordial greetings

@11101B_BarcbotsGettingThere 4 месяца назад

single acting solenoid

Have you ever had issues with the radio being in the intake cuz it's always moving so there may be a risk of dc?

@11101B_BarcbotsGettingThere 4 месяца назад

too many DCs. we don't recommend to do this.

@cucubob9535 4 месяца назад

whats the motor catridge for the puncher? ours is 12 slip to 36 which is the same gear ratio and we use a red cartidge. Its pretty slow compared to other robots with 30-35 second matchlaooding. Seeing as you have a 200 driver skills, its urs also just as slow or is anything different?

@11101B_BarcbotsGettingThere 4 месяца назад

100RPM red cartridge. reduce the amount of rubber bands to get max speed. At 100rpm you should be able to matchload 44 triballs in 27 secs. If you want to be faster you'll need to use different gear ratio and/or double slip gear.

@hongfang7869 4 месяца назад

⁠@@cucubob9535u should try out 200 rpm cartridge, 12 to 36 ratio, doubled slipped on the 36 to a 60. 133 triballs per minute so it’s pretty good for skills

@eshwarthammineni7911 4 месяца назад

Do you ever have problems with your shaft collar getting loose? Looking at the video, it looks really hard to adjust it

@11101B_BarcbotsGettingThere 4 месяца назад

as long as you tighten them they will stay in place. do regular inspections and maintenance. it's fairly easy to tighten shaft collars on motor axles.

@jackdaybell7880 4 месяца назад

There are different sizes of spacers and standoffs you can get from mcmaster-carr. Search for: Off-White Nylon Unthreaded Spacer 1/4" OD for Number 8 Screw Size Nylon 6/6 Plastic Hex Standoff 1/4" Hex 8-32 Female Thread

How do you make your C channeling black, and where and what type of plastic or polycarbonate do you use?

@timurd792 4 месяца назад

they're annodized c channels, you can buy them like that I'm pretty sure, we just found some in our random parts bins. We're using acetal for the plastic, would recommend.

@anantsinha3690 3 месяца назад

I think it’s also probably because of their leverage, so pistons have as much power as possible

@jackandhiscats2681 4 месяца назад

I would suggest using gears instead of chains because they can’t necessarily snap but great Robot！

@torchy_ 4 месяца назад

These guys won worlds last year-they know that chains are better in this case

@timurd792 4 месяца назад

we use double chains for this reason, as we need the motor closer back on the intake. we're looking into using gears on our new robot but both are an option

@hongfang7869 4 месяца назад

nah chain is fine here since it’s not under much stress and won’t be hit too much
