The first image/render that I’ve seen of the V5 educational robotics kit has been posted at the following URL: https://lastgadgetstanding.com/competitions/2018-2/entries/v5/ In the image, we see the V5 and joystick, which both have displays. We also see the motors, what appears to be a new claw ki…

Thoughts and reactions (Note: for an odd reason, I happen to know some yet unreported details) [image] BottomNotch: I need 10 individually controlled ports for my current design Well, but why? For example a passive mogo lift means you need 6 individually-addresable ports just for the driveba…

[image] nenik: Well, but why? For example a passive mogo lift means you need 6 individually-addresable ports just for the drivebase. With significantly more powerful motors, you could use just one for MoGo and 4 for drivebase. And only 3 different control values, though forget about Y cables in …

Yes the connectors for the motor are RJ11 connectors. We will have standard cable lengths like VEX IQ AND a bulk cable option with connectors and a crimper sold directly by VEX so you can make your cables the exact length you want. As far as rules for VRC, I don’t remember where we settled on usin…

Perhaps now VEX is becoming too easy…

[image] Dokkaebi: Perhaps now VEX is becoming too easy… Care to elaborate here?

Paul Copioli: I will get the particulars on the communication rates, but please remember that the motor has its own processor so the communication rate between the motor and the brain does not need to be that fast because the motor is doing a lot of the math for things like PID, etc. Again, I d…

[image] gman513: Care to elaborate here? what I think he means is a bunch of the software stuff that programmers would have to do is done for us already in V5.

[image] jpearman: It actually quite complicated to place a single number on this, but for all practical purposes the motor communications rate is 100Hz. So a user level PID loop could run at 100hz and all the built in PID also runs at 100hz? A lot of the discussion previously had lead me to b…

[image] BottomNotch: what I think he means is a bunch of the software stuff that programmers would have to do is done for us already in V5. Yep. Also a bit too “plug in and play” for me. V5 will make VEX EDR look even more like toys than the complicated machines they are.

For those of you who were not around for the transition from the PIC controller to the Cortex, VEX took VERY good care of their existing customers during that transition. It was actually a real selling point for me when I visited schools and talked to teachers about why they should invest in VRC. I…
