Re: Pixy - Axis Camera Alternative?
The LPC4300 used on the new CMUcam is more or less on par with the power in the Crio, so it would be viable to push all processing onto the camera board. The only limitation is the low internal...

Re: Software control or gearing
^This. Software control should be used anyways along with some feedback mechanism for determining RPM, as invariably the power level required to get a wheel to spin at a certain speed will change...

Re: Direct drive with CIM?
I'd recommend against going straight to 100%, as this would essentially cause a full short through the motor while it spins up and thus cause a huge voltage drop on the robot. A gradual ramp up in...

Re: Did I read <R32> Correctly? Six CIMs?
The motors will heat up extremely quickly at those current levels, too. I wouldn't be surprised if some team that doesn't think too deeply into current levels runs a dual or even single CIM setup at...

Re: motor reverse direction
If you're using the SetSpeed function, or whatever it's called now (it's been a few years), the values passed (-1 to 1) determines the speed, with 0 being stopped, 1 being full power one direction,...

Re: New Talon Speed Controller
Additionally, question about the test: Was there time allowed between runs for the motor to cool down to ambient before starting up again? If not, which runs were done "hotter" than others?

Re: New Talon Speed Controller
I take back what I said about the driver, as it could also quite easily be the increased switching speed and better MOSFET's, but for maximum power output, the newer controllers can achieve a much...

Re: New Talon Speed Controller
What are these differences in respect to? The Jaguar? The Victor?
Also, what is locked anti-phase rectification? I've never heard that used before. Most of the other features are already available in...

Re: New Talon Speed Controller
It seems like the Talon is essentially just a different version of the same thing that the new 888 and Jaguar provide. There's really no appreciable difference between them, except that the Talon...

Re: Any problems with this idea?
The black jaguars shouldn't have a problem, theoretically based on the data sheets, with 24v. Be sure not to stall the motors and you shouldn't have issues, although at the higher voltages, I'm not...

Re: Analog averaging and oversampling
The short answer:
1a. Not really. There's nothing to average if you don't oversample (if you read it multiple times in your code and average it without setting oversampling on, that's still...

Re: LV-MaxSonar-EZ1 Wires
You could probably get away with anything you have on stock. The sensors draw very, very little continuous power.

I'm pretty sure the photosensors for counting shots will still register individual chunks of ball landing in the nets, even if the rest of the ball is obliterated on launch :yikes:

Re: How to hook up KOP rangefinder
Yes, that will do it. You also don't have to write your own class, per se, as everything in java can be coded almost like in C, although it would be beneficial.
