hmmm.. mukang interesado dn aq jn ah... heheh bka pwdng aq din.... hahaha salamat creedcradle.....  Roll Eyes


ito na ang paunang circuits:

Ito ay applicable sa mga RC MODs lang.. okay?

1. ito ang Phototransistor line detection sensor



2. this is for the backwheel drive ng motor mo.. wala siyang ibang gagawin kundi ang FORWARD or stop lang


3. at ito naman ang steering drive circuit.. gagawin lang nito ay ang icontrol ang bridge mo para ikot sa kaliwa o ikot sa kanan...

walang anuman po.. nga pala. gaya ng sabi ko, pauna pa lang yan.. ung H-bridge naiwan ko sa bahay...
pero ung bridge ni parameterx maari mong gamitin... post ko na lang later ang bridge circuit

okay,
@bbench ito na ang bridge para makumpleto na natin ang BEAM mobot natin

nga pala, nagkamali ako ng comment doon sa backwheel drive circuit.. yong sinasabi ko na transistor , dapat resistor yan na 10 ohms, kung sa bagay logic na rin lang kasi wala naman transistor na 10 ohms .. Wink

ito na po!

i already built the circuit that i previously posted and it works! Thansk everyone i made use of creedcradles backwheel drive thanks



 sorry po sa crappy pics only used my phone to take the pictures:D

sa breadboard ko palang nilagay ung sensor Cheesy hanap muna ng pcb na mapaglalagyan Cheesy at LDR po pala ung ginamit ko hindi photo trans as posted

CONGRATS bro, maganda ang gawa mo Wink .. kunting PCB works at lalong magiging astig na yan... Wink Wink

@bbench
let me correct myself.. kung gagamitin mo ang entire circuit set up from sensors-backwheel-steering-and h-bridge.. then ung sa backwheel drive circuit dapat OR gate yun.. nagawa ko siyang NOR.. sorry po..

thanks, yup i made used of an OR gate because the NOR will pull the base to ground, correct me if im wrong. Wink

Yes, you have a point Wink, pero in my case, the entire logic would change, ibig sasabihin sasala ang magiging output ng motor ko, hehehehe

yung chassis is from RC Mod yan, kung may pinaglulumaan kang Toy car, dismantle mo na yan..  Wink
at walang anuman.. basta if ever na may alam ka rin sa ibang topic sa forum continue to post para marami tayong matutulungan.. the true spirit of forum of brotherhood is "Learning and sharing"

Basahin niyo lang po ang mga previous post... anjan na lahat.. later i would release my final release of this BEAM mobot.. salamat...

5.....


4....

3...

2..

1.


Ito na siguro ang huli kong paliwanag sa BEAM mobile robot thread na ito, pinagsama sama ko ang circuit sa itaas at ito ang simulation niya, at sa tingin ko wala ng tanong... just check this out,

flashplayer is needed , get it from www.macrodmedia.com ..

download: http://rapidshare.com/files/95059518/BEAMbot.zip.html
pass: www.electronicslab.ph

ito ang image ng entire circuit..

tanong po ulit Grin gusto ko pa gumawa ng isang version hehe yung hindi gagamit ng RC car for the body ung backwheel drive siya(tig isa ng motor ung dalawang gulong sa likod): feasible po ba gamiting ung inverted V na sensor array para pwede sa mejo sharp curve tapos motors from mumurahing toys and MSI IC's without microcontroller parin? TIA!

@parameterx
puwedeng-puwede! ang gawin mo i feed mo lang ang output into the backwheel control circuit..
pero twisted ends dapat ang orientation.. what i mean is the following

OUTPUT_A ----\ /---- BACK_B
                     / \
OUTPUT+B----/   \--- BACK_A

"Differential drive" ang tawag nito.. ung "caster wheel " sa harapan ay follower lang... Wink

I have a small suggestion/improvement only for the bridge circuit Smiley.
R6 and R8 are not needed.  The transistors are configured as "voltage follower".
This increases little the current handling of Q2 and Q4.
