[BLZ-i Thumbnail] Harvard-Westlake Robotics is proud to announce BLZ-i! This robot is a simple, competitive design for VEX Robotics Competition Spin Up. The purpose of releasing BLZ-i and the additional resources is for newer VEX teams to have a place to start when designing for this year’s game.…

Here is the Onshape version of the model . No download; just open the link and the model is there. To edit, make a copy.

[image] sgrunspan: I’m unclear why grinding the corners off the HA axel reduce friction. The axel seems to spin freely in the stock bearing. If it were ground down it would have a lot of play. The HS shafts have a lot more friction in the bearings than the LS ones do in the LS bearings, so sa…

It is fairly noticeable. By about a mm or two. Is it legal to shave down the sprockets?

I’m running in to that problem now. could you elaborate on what you did? Did you add gearing to the motor before it connects to the HS axel?

Yea, I just added an extra axel in between the intake and roller flex wheel that had the largest size sprocket and the smallest size sprocket on it. Then connect the intake to the big sprocket and the roller flex wheel to the smaller sprocket. This creates compound gearing for torque as the middle a…

My team is late to the jump and decided to build this bot, but it is not shooting far at all. We believe the indexer is not generating enough force when hitting the discs. How can we make it hit harder with that limited amount of space? Any help is greatly appreciated. Thank you!

Your flywheel is the problem here. You’d need to post a little more, maybe a picture, maybe a video, if you want help.

What rpm are the flywheel motors spinning at? If you built the flywheel the same way the videos + cad did chances are your issue is with excess friction. Take the motors out and try spinning the axle manually. It should be able to spin with very little resistance. The issue likely isn’t the indexer,…

I have a couple of questions. My team has got the bot nearly built but we they are working on the shooter and the intake. I messed up when ordering parts and didnt realize that I needed the 16 tooth sprockets, so all we have are the 12 tooth and I have no way of getting the 16 tooth this late. Can w…

Not really, it will be very slow. But I’m sure you can find an alternate gearing takes up the same space and uses the same wheel size and is a decent speed. Look here:
