Software / Re: Does "Webbotlib Studio" only generate C++ code?
« Last post by Webbot on September 28, 2014, 11:36:29 AM »
WebbotLib Studio only generates C++ code.
There are lots of reasons for this:- as other 3rd parties can now contribute code then it is very difficult to make sure that every contributor uses unique names for all their functions. C++ namespaces help with this.
Does that mean you have to write your project code in C++? Well not really. Since C++ is a superset of C then you can still use C for your main code - but when accessing sensors/devices then use C++ syntax such as LeftMotor.setSpeed(20). After all this is exactly how other things like Arduino work.
Software / Does "Webbotlib Studio" only generate C++ code?

In "Project Designer", the user is allowed to choose between generating C or C++ code in the "Generate Project code" window.

Does the user have the same option in "Webbotlib Studio"?

If so, where? I can't find it.
Software / Re: Problems uploading to Axon II using McUber

Yep there are different dll(s) required for 32 vs 64 bit. WebbotLibStudio (WLS) manages this for you (includes and uses the appropriate one)
Even if you don't want to use WLS to write your app then you can still use it to flash - just open the board, click the Flash icon, and browse to the hex file to upload it.

Any word from Yeta Corp?

I few more silly questions, but just in case:
- You mentioned you used com port 6. Did you verify that this is the correct port?
- Is the battery fully charged, and what voltage?
- Try a different USB cable (I've actually had one that didn't work straight from the factory)
- Try without the on/off switch, just plug the battery into the battery pin (switch can also be broken)

My last suggestion is to get a hardware programmer . . .

Hey Hero I,

Just been super busy with alot of other stuff with my company for a while, but still I didn't receive an email from you.

Were you able to get it working? Have you tried what Webbot mentioned? Also, along with the Admin's questions, are you getting any activity from either the board or any progress updates in McUber?

As you can see the project was tabled for a while, but if there is a high enough demand for an application like McUber which was meant to be:
- Cross platform
- Expandable to not only Axon but to other board (by the community writing communication scripts outside of the core application)
- House a customized terminal
+ other requested feature (can be found in other posts in this forum)

I can look into allocating some resources to get a new version out. Admin please advice?

Other than that the only recommendation I could give you is to try out the older programmer in an XP environment to ensure that your board is functioning correctly.

I dusted off my old 32 bit Windows XP system from storage, hooked it up, downloaded McUber on it and was successful flashing the hex file to the Axon II.

This proves that...
  • The Axon II is working as expected
  • The boot loader is working as expected
  • The USB cable is working as expected
  • The power source to my Axon II is working as expected
So, the problem seems to be with McUber not being able to run properly on my 64 bit Windows 7 computer.

Does McUber require the Microsoft Visual x64 Redistributable Package?
Electronics / Lynxmotion's PS2 Robot Controller (v3)
« Last post by tzankoff on September 26, 2014, 09:36:40 PM »
Hi guys! I just thought I would give you a heads up regarding Lynxmotion's latest version of the Robot Controller Kit. This is just for informational purposes in case anybody is wondering about this product.


As some of you may recall from a couple of so years ago, I wanted to add wireless control to my robot. Lynxmotion sold a different version of their kit that included a wireless controller and receiver and a separately sold breakout cable. I plugged the whole thing into my Axon II...but it did not work. However, when I plugged in a wired controller, it worked just fine. After some back and forth with some folks here at the SoR forums and the guys at Lynxmotion, it was somehow determined that some kind of clock speed issue was to blame (as I recall). Realizing that I was at a loss, I just went ahead and used a wired controller and was happy with it.

Fast forward to today. I am upgrading my robot once again by switching from a plywood frame to an Actobotics frame. I revisited the wireless control idea once again. I noticed Lynxmotion had a new version of the kit which includes a level shifter. I was hoping that this device would solve the previous problem. I was actually hesitant to buy it because I did not want to get excited about the possibility of this thing working only to be disappointed again.

I bought one of the kits...and it did not work. The receiver powered on but the controller did not...*BUT* I later found out why. I opened up the controller just to take a look around and I think what happened is that the connector from the battery tray (requires 3 AAAs) to the controller board might have been loose because once I got everything back together again (including plugging that connector back in), it worked just fine. I plugged in a wired controller again just to make sure that worked, and it did...and now that I have mentioned all of this, I am going to keep a wired controller in my bag...just in case. :-p

Hooray for me! I finally have a wireless controlled robot.

Now on to wireless audio... :-p
Electronics / Identifying Maxon A-max DC motor
« Last post by ChristianKjaergaard on September 24, 2014, 03:02:05 PM »
I just found a lot of these motors, but I can´t find a datasheet on maxon´s website. Maybe you guys know how to identyfy the motor.

What i can measure.

Weight: 100g
diameter: 26mm
Resistance: 8 Ohm

Best regards

Software / Axon 2 stuck bootloading
« Last post by jrm06c on September 23, 2014, 03:33:11 PM »
I've been programming the axon 2 without any problems. Now it suddenly (after programming it with a code revision, as usual) will not run through the initialization process and the LED does not display anything. The axon will program each time I attempt to program it but afterward the controller never seems to go into normal running mode. I've tried power failing the board but that does not change the behavior. Any ideas on how to fix this issue or what caused it?

I think I may have stumbled upon a solution on one of the home page tutorials actually.  And to answer your question, I have searched briefly here and extensively on the web.  I think my biggest issue admittedly is the technical terms that get me. 

Anyways, The solution I found showed the use of just 4 MOSFET's per each motor and had a relative simplistic description to go along with the diagrams.  I also found a 55v 64A MOSFET available through radio shack.  It listed the 64A as ID though...not sure what the ID means yet...but have an idea which tells me I should be ok.

My biggest down fall was everything I found that seemed obtainable ultimately mentioned "logic" and "programming" and that's where I went even further off the track.  I think I may be on to something with what I found though.  Didn't mention the necessity of relays and said there should be built in diodes...

Further more, I intend to make use of a VEX robotics radio/receiver that I have from awhile ago.  From my understanding just wire each of the MOSFETS to the receiver to energize the 24v circuit.  Past experience tells me that it will be easier said than done!

Did you search the forms here for wheel chair motors?
Relay motor control?
This has been asked and discussed several times.
