The underlying LEGO VM does not support the double type, just float. So, while that does not rule it out for ROBOTC, it would certainly be a fair bit of work to add it. Let's just say that if it was decided to be added, it wouldn't be very high on the current list of priorities

ok, so then I will have to wait before I can purchase RobotC.
single precision fp (32 bit) causes severe precision/rounding issues in my applications as I already observed some time ago (e.g. calculations by numerical analysis and during long-time odometric dead reckoning).

Hello,

Could somebody to tell me when is going to be relased Robot C for EV3?

Regards,

Mauro

Assuming that the development has been progressing as expected, then as tfriez said on Jan 16th there's still about two weeks left in his months time "very beta release" estimation.

Beginning of February Update:

- We have "dynamic" loading of our virtual machine running with the LMS2012 (default VM) at the same time. This is key since ROBOTC will be using the architecture of keeping the LEGO VM running to maintain the same UI and actually using the LEGO code to control motors/sensors.
- We have received a "preview" of a new EV3 firmware/kernel that is reported to have some of the I2C issues resolved and we've also received the source code to these changes (hurray!) that we're integrating into our development. Unfortunately, a lot of the modules/interfaces that were integrated were affected by this and are being modified to work with the new source code (boooo...)
- We are also integrating changes from National Instruments for their library to interface with the EV3 hardware over the USB/Bluetooth/Wifi links. This will work similar to the "Fantom" system on the NXT and will make communicating with the EV3 easier to integrate.

We're working very hard on this and trying to get something ASAP. It seems every time we promise a date, it tends to fly by for some other reasons (in this case, good news since we're working with new firmware, so less bugs!) - so instead of giving a date, I'm going to just start posting updates to this thread at least once a week keeping everyone aware of where we're at in terms of development.

Thanks again for everyone's understanding - we want this to be released just as much as everyone else and we're working hard to make it happen!

*different bugs -<-- I think you made a typo, Tim.

Any updates?

Beginning of March Update ???

Some new features in the base image are being tested at the moment to see if they can be included before the feature freeze at the end of this week.
The ROBOTC VM is being finalised so we can start testing that part (it depended on the aforementioned base image).
I don't know how much else I can tell you guys at this point, so that's why I'm being a little vague.
Perhaps Tim will be a little more forthcoming than I can be

Regards,
Xander

I have to separate questions:

* The version of ROBOTC that supports EV3, will it also continue to support NXT?

* If I purchase current version of ROBOTC [version 3.62; NXT F/W 9.68], will EV3 support come as an update or will it require a separate purchase?

Thanks,

Levan

Hi Levan,

• It will continue to support the NXT.
• You can't buy a 3.x license anymore, but if you get a 4.x license, 3.62 can be activated with it

= Xander

Thanks a lot for the answers!

Do I understand correctly, that the 4.x is this the next version which is under development now? So, if I wait1Msec(100) for the release of 4.x and buy that license, I could program both NXT and EV3? Am I right?

On this page:
http://www.robotc.net/purchase/nxt/

It only shows RobotC 3.x licenses for purchase. How do you purchase a RobotC 4.x license for LEGO Mindstorms??

Yes - If you purchase 3.x today, you'll get 4.x for free.

In ROBOTC 4.X for Mindstorms, you'll be able to program both NXT and EV3 controllers.

I am also waiting for this version.
Thinking about buying EV3 after the release.
VEX IQ in Russia, unfortunately, it is impossible to buy.
