If you had 2 cameras each detect the same object you could do find the distance to the object. If you had the size of the object in the image you could find the distance. Both of these are fully possible with the pixy.
And yes pixycams use a very simple and naive system for object detection. They do that because its the only system they could package into any reasonable size.
they were all posted within a minute of each other. Jpearman was like an “oh yeah btw we got this website” and kent’s was a “lol, i was just about to post that” so i suppose DRow’s is more official so to say
I have a question on port usage and compatibility.
The render and spec shows 21 new RJ11 ports. Those are all 4-pin power+digital comms.
Then, there are only 8 cortex-like ports.
Given the announced compatibility with older sensors, I suspect the cortex ports could be used in one of 3 modes as PWM, analog input or digital I/O.
But 8 ports isn’t much. If you’s still like to use quad encoders on undriven wheels for dead-reckoning, gyro, some pots for absolute positioning and a bumper, you’re out of ports.
This, together with waaaay more RJ11 ports than the motor allocation (and a constant grief over outdated->overpriced VEX gyro, for example) suggests that besides the compatibility with current sensors, there will be new, perhaps smart, V5 sensors.
V5 gyro (may I say full IMU?) would make sense, but bumper, pot, LED? Not so sure about those.
So let me voice this: What I really value on VEX Cortex is the least possible level of abstraction. For a bumber, you use a GPIO. Fot a pot, A/D converter input. Even for gyro, you can use raw A/D and implement the rate integration all yourself. No need to apply a full ISO/OSI model just to read a simple sensor input.
It prepares the students to understand real embedded systems, MCU applications. I hope this won’t get lost in V5.
And for the actual question(s):
What V5 sensors should we expect?
Would “smart ports” have a simple digital/analog mode as well (perhaps using passive adapters)?
Is that a planetary gear drive in the motor, that allows a “cartridge” swap out of the gear ratio’s?
If so, I wonder if it has an ID to tell the motor controller what gear ratio has been installed?
Will be nice to see next week at CES.
Edit: answered my own question, on the V5 page it describes the colored portion of the gearbox that you can see through the viewing window. Definitely helps teams know what’s going on, very nice. Not seeing the auto-identify for the controller though?
