StampUI - board

dari stampUI- nuts and volts

ini hasil prakarya rakitannya. Hasil ini cukup untuk menampilkan user interface dari basic stamp. LCD dapat menampilkan 2 baris text dan tombol ada 6 untuk control utama atau navigasi menu.

Pin yang di gunakan hanya 5 untuk semuanya.. lumayan buat saving I/O untuk yang lain.

bagini cara nyambunginnya. (PIN 0 yang paling atas. jadi yang di pakai 0 1 2 3 4)

Daya bisa menggunakan sumber yang sama di pakai oleh basic stamp.

Interface Parallax Basic Stamp 2 dengan SPC Relay Board v.2.0

untuk proses mencobanya saya memakai DT-51 Min System 3.3 untuk mengecek bagaimana cara bekerjanya. si DT-51 terhubung dengan 9v yang sudah agak lemah, dan Relay Board menggunakan 6v batterai ABC, semuanya berjalan lancar dengan sample yang sudah di berikan dari CDnya.

Lalu barulah saya pindahkan ke basic stamp dengan menggunakan resistor 220ohm sebagai jaga-jaga arus balik ke PIN.

Konfigurasi ini menggunakan batterai 6v (4x AA) dan menghubungkan board secara serial.

Teknik coding di Basic Stamp Editor hanya menggunakan:

HIGH 6 ' untuk menyalakan pin no.6

PAUSE 1000 ' untuk 1 detik

LOW 6 ' matikan pin 6

END

PS: lihat manual.. Input 1 pada Relay Board harus di hubungkan dengan ground.

Interface Parallax Basic Stamp 2 dengan SPC DC Motor

Konfigurasi dengan DT-51 seperti ini dapat berjalan dengan EXAMPLE.ASM sebagai programnya. Menggunakan baterai 9v untuk DT-51 dan 6v untuk SPC DC nya. (ground tetap di hubungkan bersama) Kabel pita dari PORT C dan PORT 1 ke tempat yang sama.

Perhatikan arah kabel pita.

Tetapi saya belum bisa merangkai I2C command melalui basic stamp. jadi SPC DC Motor saya hubungkan seperti ini.

tetap di beri resistor 220 ohm untuk menjaga pin. SPC DC motor controllernya di beri tegangan yang sama dengan Basic Stamp (6v). Tetapi Vmotor saya berikan baterai 9v untuk memutar motor lebih kuat.

(saya belum mencoba dengan 12 v)

Cara memprogramnya justru di berikan LOW pada pin yang bersangkutan.

LOW 6 '(start motor)

LOW 7 '(searah jarum jam)

HIGH 6 '(matikan motor)

Leaf project - another bot life

After reading Dr. Bruce www.leafproject.org and playing along with the LISP... it's very inspiring... I decide to make my own leaf robot. Excuse me for the bad english in this site, but i will try to make this in 2 languages. English and Indonesian. This robotic thing is far from my expertice but i really want to build a robot. So this is my shared experience.

So many thought and dreams so .. First one.. my short term GOALS by priority.

1. I would like to have a mobile workstation for my laptop, i usually change place while working.. living room, backyard.. etc (still in my home)
2. Making the robot available to Indonesian language is better.
3. I don't watch TV so much  but I would like to have recent news from selected RSS internet feed
4. Communicating with people.. i mean telephony system in my robot.. i can perform calls from my laptop and vice versa.
5. I want to check email.. and someone read it for me.
6. Browsing the internet by voice or virtual touch (without mouse?)
7. Entertaing robot..
8. I have music clips or movie clips that i like to see many times. (building database and a navigation menu for search)
9. I shared my laptop with my wife, and some other people.. so i cannot close the laptop for only one software. maybe other people can use the system too..
10. Video capture
11. I love music and love playing drums.. i want to have a recording station while jamming with my friends.
12. Chatting with the robot would be nice
13. Should be relatively cheap.. =)
14. I like to have a menu system for my robot
15. The robot should have a brain for navigating my house.
16. The robot can recognize face and objects..
17. Home controlled by robot.. this is good
18. Robot Emotions? Leaf have that
19. The robot can take or bring me something... (i think it's very hard)
20. This one is really deep..   i want to ride my robot. transportation in my neigborhood maybe?? (last priority :) )

First step.. the body construction.

my first robot was the BoeBot from Parallax that's where i understand a little bit about robot.. so i know a little bit about differential drive.. base on that, i sketch a new frame for my little boebot.

like a table with wheels right?.. i think this is the basic need for my robot.. i hope i can improve the design next time. but this should cover my need right now.

Finding the motors.. after browsing in the internet and real shop in my country.. i cannot get a decent motor to use for my robot without spending too much for this experiment.. so i went to a flea market.. and found a couple DC motors for the Power Window in cars (used). i can get them for approx $15 for two motors.  (Rp. 150.000)

and the wheels i spend $9 (two wheels 20 cm and one smaller one)

for connecting the wheels to the motor i buy a matching plumbing bolt and then i weld them for $5. This is the final result.

and this is the motors..and the base construction

putting together is like this.

finally mounting the wheels on the base. using some L shaped bracket.

I take all the woods from my used kitchen set.. i think this is the fastest way to build a construction and very flexible..

maybe i upgrade to aluminium frame next time .. or fiberglass. Now.. just wood.

i pick this H-bridge, apparently this is the only model i can find in my country.. it's expensive for this experiment but it was worthed, i buy 2 of this.  $27 for each (Rp. 270.000) it's a 30Amp H-bridge.. i think i can still use this when upgrading my motors

First run test..

 

I have 2 basic stamp board (one original and the other one is indonesian version of basic stamp) and one DT-51 Minimum System v.3.3 board, this is from my previous learning the basic of robotics.. i decide to put them all in my robots. I have also eb500 (a bluetooth module), The basic stamp is easy for prototyping so i decide to put one basic stamp with eb500 as a master controlling other microcontroller.

I learn connecting them by reading this.

ok.. then i build the rest of the frame.. it's like this.

i add speakers and webcam on the top of the pole. using hot glue gun.. i think it will stick.

i use the old servo from boebot for the webcam for the pan and tilt. again, using L shaped bracked with the hot glue gun.. i put them together like this.

covered with some cutted socks.. it looks more funky.. =)

That's all for now, next time i will write about the software building for this project.
