VEXpro 2016

Are the gears in the VP integrated encoder 1:1?
Any updates on the plastic versablocks to fix the stripping issue?

Very nice job on the DC motor tutorial, I have taught this subject many times. Understanding these principles is the key to properly designing any electrified mechatronic device. This tutorial is very well laid out, and does not use any concepts which are above high school levels of understanding. Nicely done!

Agreed. Very handy explanation.

Having the 50% power for 180 seconds test, as well as the stall at different voltages, will be super handy for sizing systems.

Woo! Drop down modules! Grasshopper drive for all!

Looking awesome guys. The motor selection guide looks awesome and will be a huge help to all teams.

However, I noticed a small units issue for calculating the peak power that you may want to fix up.

Work = 196W should be Work =196J
and then Power = Work/time

The 775pro looks totally awesome. I am very happy that we no longer have to purchase from BaneBots.

I'm confused by the section in the motors guide that starts with "Note: Current Draw at Peak Power"

196 watts is not the power requirement for a motor to lift 20 kg 1.0 meters in the air. Power depends on the speed at which the box is lifted and motors should be selected based on the power required from them, not the amount of work being performed. The units are also a little questionable.

From what I see, there's nothing that says that the 775pro is going to be legal for the 2016 season; (I guess the same could be said about any other motor) albeit FIRST did decide to not allow the Banebots ones anymore due to the supply running out.

It just concerns me that on the page for this motor is does not say it is FRC legal, unlike the CIM motor.

Technically we won't know until the rules come out with the game. OR if FIRST decides that people should know before kickoff that it is or not FRC legal.

I believe you meant 50% speed . The test is at the theoretical "max" power

VersaDrop is perfect for h-drive.

Yes it is. VersaDrop makes it so much easier to build a nonadrive, or as I like to call it, butterslide drive. My favorite part about the VersaDrop is that because it's COTS, you can bring extra modules with to competition without them counting against your withholding allowance.

Any idea on when the new items should be available for order?

WCP has the stuff up for ordering, still modifying the pages a bit tho. We will not be shipping out new items for about 1-2 weeks.

So, no way to get them before new years, for international teams with a 1 week shipping time?

We won't be able to sadly but if you call the folks at VEX I'm sure they can make happen for you (no guarantees but please give them a call). We are receiving stock from VEX.
