I have built several Adventure Bots and have not had any issues, but when I tried to build a custom 2 WD robot using IoTiny I've run into a strange problem.
Using the same "continuous rotation servo with Wheel" set from my Adventure Bot I found that they worked for about a minute before refusing to run any more.
I thought it might be just a coincidence, so I took another working set and first tried that with a EZ-B v4 controller in a Power Shell with the same "LiPo Robot battery" (after a full recharge) that I was using on IoTiny ... and those wheels worked fine
But, when I connected the wheels back to the IoTiny, the servos worked for a little while and then stopped working!
What's worse, is that I reconnected the servos back into the Adventure Bot and NONE of then worked anymore.
Upgrade to ARC Pro
Your robot can be more than a simple automated machine with the power of ARC Pro!
And then maybe try a metered test on another I/0 port, again sending control signals to the port with no servo connected.
@Jeremie, is there a check list to check the I/o tiny with a meter for proper voltagages or continuity like there is for EZbv3? EZBv3 Diagnostics If not do you think you might be able to help us come up with one?
I figured it out, but I gotta run. I'll let @DJ fill you guys in!
Oh and the IoTiny Datasheet is almost complete, it's just being edited and reviewed before release. It'll definitely help with diagnostics.
Could the tape be a problem?
Anyway lets hope @Jeremie and @DJ will look into this...
Contact us to warranty the continuous rotation servos.
However, in the meantime we are looking to see if there's a possible firmware solution, or if the servo pcb revision needs to be reverted.
P.S. I broke those 360 servos and I would never use them anyway... Thanks for the warranty offer but I am good... No need...
Thanks for confirming this...
Thanks for the great support on your products. I did ruin a few in my testing as I couldn't believe what was happening as others didn't see the issue.
I will contact warrentee support
I agree that the new HDD servos are amazing
DJ mentioned the possibility of reverting the servo's PCB.
Is there away to know if is the old(good) or new(pcb) before i connect them to the Iotiny ?
I know the lever arm and 180 degree servos are now HDD but I haven't seen any mention of HDD for 360 degree servos
@Jeremie mentioned that the plastic gear 360 degree servos work with IoTiny
Not sure what the problem is, but I wouldn't try anymore new ones with the ioTiny until something is fixed.
I just assumed I had bad parts as others were saying the didn’t have the issue
Thankfully, Jeremie confirmed the problem
I had only 4 .... now i have 0
The life of a servo at times may seem short but for ptp these servos never matured to warrenty expectations. When one servo dies, another is manufactured and perhaps even will go on sale. We must remember to keep our part stocks up, so that we may never say we have zero servos!
Please, a moment of silence for ptp’s servos. lol
Yeah, well. I so go big or go home :), and hindsight is always 20/20.
Was the end of a long day, and the first time in many months I have had any time to spend with my robots. Decided I should test all of the servos I got in my HDD upgrade box (SIX, Roli, and Dev Kit upgrade) before the warranty ran out. I had already rebuilt Six, and was running through the rest of the servos. First one died, and I recalled there was a problem mentioned on the forum, but didn't go look it up. Seemed to recall that it was just some of 360's, not all of them (whoops) so tested all 5, and all 5 died. They sort of worked setting the port between 90 and 180 (movement was jerky, but working) and then as soon as I went in reverse, they stopped responding.
Anyway my lesson learned that day was, always test 1 at a time and if you try 1 and it burns out you don’t just keep plugging new ones in.
