Let's Make Robots!

What is the problem?

So my robot does work when it is connected to us or usb and 9V, but when it is connected only to the 9V
Everything works with little pulses and long delays!
Is this a good code even?

 

#include <Servo.h>

 

Servo servo; //Create a servo object

 

//Standard PWM DC control

int E1 = 5;     //M1 Speed Control

int E2 = 6;     //M2 Speed Control

int M1 = 4;    //M1 Direction Control

int M2 = 7;    //M2 Direction Control

 

Axe - the sumobot

Hello hello!

As you can guess, I am making a new robot, and it is a small sumo!
Features:
- Picaxe 14M
- 2 modified micro servos
- 1 LDR to see the line of the ring
- Sharp IR sensor
- Bottle cap wheels until I make up a better solution (Yes, lol :D)

And when I will receive parts, or get something done, I am going to update this until it is time to post a robot!
Tomorrow (I think) I'm going to post schematics and maybe printed layout ready to make it pcb!

Have you spotted THIS?

Let's Make Robots!

So i found this when i looked where members do live.
There is green colour in the logo!
Did you spot this before me? 

Biped robot

Okay. If you know i am building cheap 4-DOF biped.
If you want to know what would it be,it's going to be like EasyBotics Easy Biped :O 

24.11.2011
I got some ideas and i ordered 4x Hextronik HXT900 servos.
Next thing i buy is PCB making things and PicAxe 14M. 
I make chassis when i get some plastic sheets.
But i can tell you some things:
- It has a homemade IR sensor
- And led eyes
- I can modify it easy to walk and avoid obstacles or be a sumo or dance
- I may add an IR receiver to remote control mode 

My first picaxe code

*********************************************
* UPDATED: CODE                          *
*********************************************

Hello! I have 2 years exprience in programming before i doned this.
Now i show this to you because i want to know does it work.
Sensor thingy is my own maked i tell more later.
I debugged the code and it worked. It uses Tri-state motor controlling, check nuumio's tip about it!

 

 

'Obstacle avoider with sound

My parts

Yes! My parts arrived today and now i got them.

There are over 400 parts in this box (not include picaxe things):

There are ldrs,resistors,electric capacitors,ceramic capasitors,motor driver,08M,transistors,leds,axle,wires and lots of other things what i can use on robots. But still i have to order more parts, motors,breadboard and battery holders.

 

Robot chassis

Hello everyone! Now i finished my robots chassis and i want to show it to you.

First picture is front of it:

And secon is from left side:

And these are wheels i may use on it:

And parts are taped with two-sided tape.

Sensor seeking.

Let's Make Robots! Hello LMRians! I ordered some parts and i order more in few weeks.

I want to do my own sensor using LDR,IR led and normal leds. And yes, it's going to be something like AmandaLDR but not exactly same.

The sensor is going to my mini sumo, project what i'm working for. It's using Picaxe-08M. What do you think about it?
