Hi,

I am starting this thread for all the roboteer in Malaysia. Maybe there are many people out there with this hobby.
Might be some day we can form a Robotic Club in Malaysia.

For starting here is my Robot. Still under construction.

what processor are you using? programming language?

1. Basic Stamp2 Programing language Pbasic.

2. PIC 16F877 Programing language PicBasic Pro.

Still learning.

is this like the lego robot or more advance??

hey..i would like to start some robotic project too.. can you put more information on the basic tools needed.. i would like to know about PIC, the programmer and the compiler and etc.

HI azmax100. I think I saw that robot before in some other forum. What does it do actually? The skull looks a bit out of place.

Here is a close-up of what I am working on.


Here's few sneak peek of the electronics which I am currently working on:


The 2nd picture maybe familiar to some RC fan.

Rokiroad: nope, this is unlike Lego Mindstorm because there isn't any bricks !!

Enferno: PIC is basically a category of IC, called microcontroller (a.k.a uC). PIC generally refers to microchip uC. Another popular controller is Atmel. For programming, the 2 most popular language is assembly language and C. Various compiler used different C syntax, but they are actually quite similar. For free compiler, you can try MPLAB, official software from Microchip, comes with assembly language and C. You will need a programmer as well to download the code into the uC. You can get a lot of project video in youtube.

P.S.: I hope this thread would not be hijack by advertisment and announcement like the other robotic threads. Hope TS could monitor this regularly. Cheers!

I'm trying to build a simple H-bridge circuit to control the motion of a DC motor. but the motor failed to turn. any advice will be deeply appreciated. btw, i'm using the identical setting.

If you are using identical component, considering the components is functional, there are 2 possibilities:
1. Wrong wiring connection
2. Wrong supply

Try and post a picture of your prototype. By the way, most H-bridge use 4 common transistors. Using 2 PNP and 2 NPN is confusing, you need to connect to supply and ground.

this is my setting. i'm testing this circuit using a TAMIYA DC motor powered by 3.7V Li-ion battery.

lego got robot kit..

Your circuit looks correct, seems like you duplicate the circuit up to jumper cable color. Anyway, did you connect your resistors to supply/ground as indicated in that website?

yup..i tried various combination.. i should try it with a diff dc motor..

ey, why the resistors all not grounded?

How about trying using LED or bulb? Easiest way to test if there is current passing or not, and also good way to test the polarity. If using LED, remember to use at least 2 LED in series. If not you may oversupply the LED as typical LED is rated at 2~3v.

Used to have NXT Mindstorm, but I sold it off it already cause hardly play with it.

spacelion: it's ok if the used resistor is not grounded, as long as there is no passing current, the transistor would not be activated. But just in case there is a leak, better connect the resistor to either ground or supply as indicated in the link.

p.s.: I have experience where breadboard do leak current, maybe that's the problem.

what are you working on? i could see some servos, receiver pack and 2.4Ghz tx

Nice observation Some remote control stuff that is! Some gigantic robot to take over the world... (I wish ) Anyway, haven't got much progress since my last post, busy with work. Hope to get a few days break, can focus on it.

Hi,

Anybody want to start this hobby can try Arduino. I found it easier to program than PIC and cheaper than Basic Stamp.
No need to use programmer. You can write your code using "sketch", a free programming software.

For details please visit www.arduino.cc

Any questions about Arduino are welcome.

Hey Roboteers,

I'm building one now...

still got anyone around?

Nice robot azmax, planning to scare children with it

Show us what you have. What uC are u using?

I only got the circuit board done... the rest is still in design

Anyway, are there any robot competition open to the public? NRC and RoboFest are for students only...

We should organize one..he he

How bout Lyn Robot competition for Lyn members..he he

He he he ... sure why not but we need more people to join the competition.

I am more interested in automated robots but I still like a good RC robot bashing...

I already made my line-following robot track.

Just a basic track, the size of the board is about 54 x 75 cm



The robot starts at the T on the bottom right and follow the track till it reaches back to the T.

yeah...Just finish last week Abu Robocon, created 3 robot is awesome learn a lot of knowledge....Hope u all guys can share each other..Thanks

Guys im a newbie and im interested on building a robot and since my final year project i need to build one.so if anyone kind enough to share their knowledge or tell me where can i find a shop that sells tools and part to make 1.thanks.

the component can find in Jalan pasar, NiXie Electronic shop. Cytron in Johor and Jalan Kelang Lama,Ampang, Farnell in Subang

Farnell got shop to COD? I thought have to use their online service to purchase components.

Hey Guys,

Arduino Malaysia Forum is now online.

http://forum.myduino.com

You can order via online and then they delivery to you company or university. I know their company base on Subang.

Good news, Farnell deliver right to your doorstep free delivery for orders over rm20. Although the waiting period for components from UK or US warehouse can be long. One tips when selecting components online is to use the Price Sorter to find the best price.

Robocon 2011 Theme release already....

They have this robot competition open to "not student anymore" (its battle robot genre)...build a robot to crush others robot...organize by MMU melaka - robowars and organize by uniten - robogamez.

Can I know any post that sell robot parts that include everything? I am really interested in building one myself and have some fun. But I dont know where to get the material.

I saw someone selling at lowyat forum before, but I cant trace back the post anymroe T_T

bro,i intrested in build a robot...what starter things should i start?

Gray04 maybe you can start with Arduino. Easy to learn and unlimited abilities. You can get from local Arduino distributor http://myduino.com
Price is cheap.

interesting, lost a bit in robotics.
deserve to work at it again.

Is this thread dead? Im gonna start building a biped robot was wondering if got ppl who would like to collaborate/bounce ideas off.
