Meccanoid G15X2-KS

June 22, 2017IMG_20170617_050555.jpg

Meccanoid G15X2-KS.
Power Dwarf.
Good for pushing over G15KS and XL.

Hah.
X2-KS is for the second G15 that was scavenged for its parts and KS firmware flash to handle four additional servos in KS configuration. Kept short in stature for now.

Stay tuned for G15-X2KS Texan. Which may or may not happen. G15 servos (AKA CAM 03, Blues) aren’t as powerful as G15KS( DEV-06 Yellow) and will go Arduino or ESP8266 with an Arduino. Necessary for what I want to do.IMG_20170617_050709.jpg

I like the KS firmware voice soooooo much better than Lollipod Kid helium huffing IMG_20170617_050730.jpgWizard of Oz G15 voice. Anyway… alternative build.

Systems Check

Another firmware is out for G15: English US G15(and KS)-2.8.

Not exactly sure what this adds or fixes.
It does NOT fix “Adjust Volume” voice command. Still stuck in SET ALARM response.
KS and G15 versions.

The only option to adjust volume right now is download the English UK – 1.9 firmware.  Use “Adjust Volume” voice command in settings menu to set where you like and then re-flash 2.8 firmware. Of course you have to suffer horrid British accented Meccanoid fora bit. Was waiting for to go Mary Poppins song step. Didn’t happen thank goodness.IMG_20170616_171204.jpg

I suggest highest volume and just tape over speaker if needed.
Of course if you speak another language can try flashing that.

The 2.8 firmware has more features than the 1.9 firmware for ROBOT Mode.
If you’re running in DRONE Mode then probably don’t need it.

Sad? Yes. Sadder still: Why is the UK ROM stuck in 1.9 land o the past?  I’m conflicted that it’s useful for back-stepping but don’t fathom why UK version is neglected.

Then out of curiosity I clicked off the different languages through the Robot Updater

and fOuNd:

Language: Firmware Version G15 / G15KS:
English (UK) 1.9 / 1.9
French 1.7 / 1.8
Spanish EU 1.6 / 1.7
Italian 1.5 / 1.6
German 1.4 / 1.5
Russian 1.2 / 1.3
Japanese 1.10 / 1.11
Dutch 1.3 / 1.4
Spanish Americas 1.0 / 1.0
Danish 1.2 / 1.2
Swedish 1.1 / 1.1
Norwegian 1.0 / 1.0
and hopefully to embarass:
English US 2.8 / 2.8

Wow 1.0. Seriously ugly stuff. For the G15-US-1.0 was horrible because of battery voltage reading was set too high and would shut Meccanoid G15 down within a few minutes (about 10-20 minutes) with there being plenty of life left in batteries..

Programmers dropped the ball or ran away?
Somebody must have spooked them or there’s a shortage
of tater chips, popcorn, caffeinated drinks, and coffee in certain places.
Possibly a cheese curls deficiency.
Though reasoning suggests a relatively unknown processor / parts and lack of
documentation in anything other than Chinese is not helping.

Mentioning China and not seeing a Chinese firmware.

Fuse blown there.

NOTE: Flashing new firmware results in Meccabrain doing a diagnostic which must be completed in ROBOT Mode or App will lock out. The completion of startup system check requires all servos for whichever ROBOT (G15 or G15KS) and light bar be in the jacks in accordance with directions. Drone Mode in App will also be locked out.

Meccabrain will operate in Drone mode but not the App.

***No you don’t need to build the robot to complete diagnostic. Need servos, Smart LED bar, battery and of course Meccabrain in proper order as if they were installed in Robot. You can leave the foot motors disconnected but that may change with newer firmwares.IMG_20170617_050801.jpg

I’m sure the hacking community has moved to their own hardware and
only using “smart” servos and Meccanoid pieces. Fairly slow.
I have heard some bitching about parts not being Meccano or Erector style. Only compatible. Pieces aren’t what die-hard fans are used to and don’t exactly promote free thought open build mentality. Shapes are irregular and not typical Erector / Meccano simple shapes. They also have pinned keys limiting use. Interlocking pins of new parts requiring orientation have more to do with slow build times and aggrevation.

That’s my opinion partially based on  evidence.  Half-inch standard still theremostly. Being made of plastic not helping standing with the classic folks.
Poorly documented protocol under the ‘open source’ mantra. Not really open source and is only for Arduino program that communicates (protocol) to servos and light bar.

Meccabrain , not the Arduino program “Meccabrain” , locked out. Not OPEN Source.

Well mostly. There’s no reason why protocols can’t be abused to further capabilities of Meccabrain with other hardware as servos.. Still limited in programming through Application program which really isn’t that good. Usable but unpolished and quirky. Is good thing protocol was released with Arduino code. Meccabrain(tm) mostly for starter use. Any reasonable advanced use limited. Voice control is cool but practicality dysfunctional. It is a decent micro but its stuck pedantic cute-ware and BLE comms thru ‘App’. L.I.M. is nice idea but inability to save off line and transfer to other devices makes it barely useful and anti-social. Yes this robot is anti-social but it can joke about it… so it’s fine. No driving motors control available through LIM but may be hidden. Inability to shut off sound recording whilst programming

IMG_20170617_050746.jpg

in L.I.M. also sucking useless. Inability to add sounds to Meccabrain without motion equally irritating. Tape to the rescue again. Right over the MICrophone hole. Not100% effective but what-eee–ver you need to do to achieve desired results.
**** Limitation of L.I.M is roughly 3 minutes times up to 15 programs. ****
So technically up to 45 minutes of L.I.M time but only 15 labels..Don’t know if that will change.

 

Yes I could go on, and will. Laters.

Meccanoid G15 Brain Surgery

Oh the Horror

Not exactly Brain Surgery.  It is a brain of sorts.

Having trouble with the clock not holding time since day one I knew I’d have to replace the clock battery sooner or later, or so I thought.  Ha.

After updating the firmware flash and downloading the new App; the clock not functioning is now an issue because the drag and drop “behavior” programming has a use for it.  There’s also a hidden function in ‘settings’ menu that allows setting an alarm.  Woo hoo.  I was thinking that would be a nice function about a year ago.  Scary.

I had it apart once before but only for cursory examination  to check the board to see if it was indeed the one that had a clock battery and not a third farad capacitor.  Sure enough it had a battery hard soldered.  Not having an extra one of that type or any other suitable replacement to be soldered in I quickly slapped it back together without much further examination.

Oooops.   Ya.   Assumptions and all that.  Take a look.  Nice solder job.  NOT.

g15-controller-4

Can you see it?  Just above the clock chip.  No?  Look closer to battery to the right of “C24”.

g15-controller-5-1
Somethings aren’t better at higher res just uglier.

How about now?

g15-controller-7-1
Magic.  All purty like.

You know when you give a people a bowl a rice a day and work for 14 or more hours this happens.  I’m just saying.  I could be wrong, but given that the vast majority of chips on this board are China Mart , probably not.

There were some other nice pieces of solder slag laying on the board.  I’ve become accustomed to checking boards from overseas manufacturers.  Not only China.  Please don’t think I’m picking on China.  Many manufacturers produce quality products cheaply.  This is not one of those.  Lots of nice cold solder joints too.

g15-controller-6
Short waiting to happen.

Here’s one the larger pieces for example.  Doesn’t look like much but was laying across traces next to the blob.  The black blob is the CPU/MCU.  It didn’t appear to be attached by anything other green protectant paint layer.  Most were like that and smaller.  Not cool.

Checked the clock battery at 2.85VDC,  not great but good enough for a while.  Not worthy of a replace.    Cleaned up what I thought I should and put it back together.  FWIW that solder slab was shorting to clock crystal to one of the clock IC pins.  The clock does work now.  However the Firmware /ROM has issues.  More on that laters.  ONE Down.  Pencil in another dozen problems.  Sigh.    A few more pics for ya:
