General Discussion / Remaining Developers?
« on: June 15, 2017, 05:58:09 AM »
Hey,

I am a bit sad that a lot of the main developers for Alpha 2 are selling this robot or moving on.

Even with a lack of updates from Ubtech, I still think that if we got together, we can develop some neat community programs for Alpha 2.

Hoping to inspire others to keep their robots and to develop, I'll soon upload videos of some of the progress I've made for Alpha 2, including the ability to track a ball via opencv and walk towards it, gyro-balancing, and I've also replaced all the ubtech's voice recognition/speech with Google's voice and speech recognition, and I also got Alpha working with Wolfram API so he can now answer random questions.  I've been quite busy lately, and haven't made more progress.

Writing apps and coding / Servo Lower Level Access
« on: January 24, 2017, 05:26:56 AM »
I've been trying to get some more information on the protocol that's used to communicate with the Servos.  My understanding is that it is serial, but I can't seem to find any documentation on their servos, just their spec on torque, dimensions, etc.  I wonder if they use a similar protocol as the dynamixel servos.

I am hoping to bypass Alpha2Services and work directly with the servos.  From my bit of testing right now, there's really no way to set a new position while the servo is moving, seems to freak out when there's a new motion position before the first position is reached.  Also, I want to be able to get current feedback from the servos for bump detection, etc, but this information is not available in the SDK.

Hopefully someone will have more luck with trying to figure this out.

General Discussion / USB Debugging Off ... Maybe?
« on: January 20, 2017, 09:02:30 AM »
Hey All,

For no apparent reason, I can no longer connect to Alpha 2 via USB to debug, I also no longer see Alpha 2 folder in "My Computer".  I was using Vysor one moment and the next moment it stopped working.  Alpha 2 is still running Chat Partner and I can still connect to him via Wifi with my phone / pc programming, but not through USB.  Is his USB port possibly damaged?  Is it possible that the USB debugging turned off on its own?

Any help is appreciated! Thanks!

Writing apps and coding / Sonar Sensor Access

Hey All,

I just started coding for Alpha 2, does anyone know how to access the proximity sensor information?

Also, I recently tried Neuron and it is great app!

Thanks,
Alan
