was trying to test this hexapod robot..

then the bluetooth module gave up..

removed the bluetooth module then connect the servo controllers sa pc using usb to uart module... was able to make the hexapod stand then after a while, habang minomonitor ang temperature ng mga servo, may nangamoy, at heto sya...

yung mga servo na gamit sa hexapod na ito ay galing sa alibaba and ebay, and they were NOT ORIGINAL Tower Pro SG90 Servo's, japeyks kumbaga... nilagyan lang nila ng sticker.. was able to purchase them for around 2 to 3 dollars each lang... original Tower Pro SG90 Servo has a TP marking at the bottom plate of the servo..

Sayang ganda pa naman ng toy nyo.

baka isolated case lang yan servo.. meron din ako ganun, kakabili lang tapos pagdating sa bahay, naputul yung isang wire internally... binuksan ko nalang at resolder, zt ok na ulit... baka may naloose yan at nagshort

umiinit talaga sila, i think di rated para dun sa torque as advertised..

mosfet ba yung nasunog?

toasted siopao · « **Reply #6 on:** December 14, 2011, 08:19:27 PM »

yup, di ko alam kung alin nauna nasunog, kung yung mosfet or sumubra init nung motor, baka ang taas ng hugot ng stall current..

napapabili na ako ng bagong set ng servo, baka magmetal gear na.

kahit sa RC forum notorious yang SG-90 servo na worst servo.
cheap lang sya kapag wholesale and designed nga... for aeroplane.
then again. ayun nga you get what you pay for.

maingay siguro yan no? eeeeeek eeeek ik pskkkk pstt eek

insomartin · « **Reply #9 on:** December 14, 2011, 09:31:32 PM »

yung original single chip lang. walang apat na external mosfet/transistor h-bridge.
IC: AA51880

tsk tsk. .hirap talaga. bakit kasi nagmamanufacture ng fake eh.

toasted siopao · « **Reply #11 on:** December 25, 2011, 12:05:58 PM »

Testing again if how long tatagal ang metal gear servo bago uminit..

nice.

ate glenjoy, may laser cutter ka rin? nice!!

video!

anu po ung microcontroller na gnmit nyo? ska nkakatgal po b ung battery? 17 standard servo po ksi ung nid nmin controlling gmit arduino mega, anu po ung isang circuit board n nsa ilalim ng microcontroller

zrehtiek/keitherz · « **Reply #15 on:** January 15, 2012, 02:16:53 AM »

wala atang micro except dun sa micro na nasa module.
sir toasted siopao is using this module:
http://e-gizmo.com/KIT/servo16.htm
and the bluetooth module is directly connected to it i think.
see the pdf of the module.

I used the rechargeable battery from e-gizmo, SLB-1674 yung model, bilhin mo na rin sa kanila yung charger na kasama. If you are asking about sa microcontroller na gamit to produce na PWM, wala ako ginamit, instead ginamit ko yung 16 servo controller ng e-gizmo, dalawa nun to control the 18 servo.

Yung pag control nung gaits or yung sequence ng movement ng legs, gamit ko is pc kasi I am still testing the gaits.

Ok naman ang arduino mega to control servo pero I am not sure if they can drive servo motors simultaneously, the beauty of using servo controller is that yung pag-update ng servo sa position nya ay independent na sa main controller mo.

soon, magkakaroon din ako ng ganitong assembly (4-legged nga lang).
thanks, t.siopao!

for now, prototypes lang muna..
part II. using LPC1114 w/ CoOS:

pre-calculated ang ik mo or real time?
