Re: WCP: 2017 Product Launch + MCC 2017
This looks awesome! What material/dimensions are those polycord pulleys? Your website doesn't seem to list them. Only the materials/dimensions of the hubs. Unless your pulleys are 6061-T6 Aluminum......

Re: Drivetrain PID tuning
Gyros don't track linear displacement. As Jared said, they track the rate at which the angular displacement is changing.

Re: Drivetrain PID tuning
How do you accomplish this? Do you just set your setpoint proportional to the position of the stick?

Re: New AndyMark Product Game Hint???
Hm... What's that plastic bit in the middle of the wheel? I hope it has some way to interface with a hex shaft nicely.

Re: New AndyMark Product Game Hint???
I didn't. I don't actually have any hex shaft stock in my house (I live in an unusual household). That being said, I do have a couple of creative ideas using what I have on hand. I'll see if my...

Re: New AndyMark Product Game Hint???
Sorry to revive a dead-ish thread, but over the holidays I'm training some new programmers with a kitbot we assembled before the break. I am happy to report that these do fit on .5" hex shafts very...

Drivetrain PID tuning
Today, I was encouraging my rookie programmers to utilize the NavX to experiment with PID Control in order to make our robot drive straight. Given that we've never done this in a season, one of the...

Re: Tool list .rookie team
Alternatively, you could put a tote on a smaller scale, tare it, then put the robot on top of the tote. A bit of a janky solution, but worked well for us. :)

Re: Tool list .rookie team
I would definitely suggest these, but I'm not sure about what their budget constraints are. They did say "minimal" budget. That's why I went the hand tools route.

Re: Tool list .rookie team
Since you're on a budget, I'm going to go the route we went for a couple years. We didn't have access to a space where we could set up permanent bench tools, so here's a list of essential hand...
