RC Robot Car wheels turn too slowly

I have just put together a basic rc robot car, based on an arduino uno, motor shield (as I fried the original circuit board trying to measure voltages :) and of course a basic rc car (new bright). I can get the car to turn its wheels left and right and get the wheels to go forwards and backwards (when in the air) however the forwards and backward wheel speed is lacklustre (analogwrite(11, 255)- to the point where if place it on then ground the wheels don't turn and the car doesn't move. If I connect the rear wheels to the battery directly (9v battery) the wheels turn ok.

RX TX pair of small RC car Project

Hello Guys,

Had been away for a while..

Missed you all.

So this time I am working on a project of a RC car

Small on easy one yet i am stuck in the RC part of it...

I want it simple,

I know I can achieve this with Arduino XBees and all but this time I wanna keep this simple..

I want a TX RX pair with which i can just run the motor with the help of a switch..

thats it...

Just a button connected to TX and a motor connected to the RX along with the battery

Raspberry Pi Lego car

Hello all,

I'm making my first robot using Raspberry Pi. My robot looks like a car with three wheels. Two of them are in front and have connection to motors, The third one is behind and it's no connection to motors.

I'm planning to use 2 simple motors (for each front wheel one). For now my robot weight 260g, and i have to add two motors and battery and i little of more constuction for holding motors and battery. I'm already found which type of motor should i use:

Motraxx MOTOR X-FLY 400 or Moteaxx MOTOR X-FLY 280.

Car alarm remote control repurposing

A while ago, I got hold of a car alarm unit and its two remote control fobs. When i hooked it up to 12V I realized that it didn’t  work, not responding to any of the commands from the two fobs even though their batteries were OK. Naturally, I opened up the unit to start harvesting parts and noticed the RF module within (the one that sticks out perpendicularly) and I figured it shouldn’t be too hard to use the module with an Arduino.

Battery help

 

Hi 

What is the difference of a 9v battery and a battery holder that can hold 6 aa batterys 3 on each side? (it comes out to have 9v) Which one is better for the arduino or any other microcontrollers??

Rc car re-interfacing with a home pc

Hello,i am quite new to the world of robots and so to get started i bought an rc car from a local store.The key thing i want to do is to change my rf remote so that i can use it from my pc.Now is there a way to change its board or rf remote configuration or the second thing i may think is to buy a new board and interfacing it to the pc via provided interface.The chip used is in the rf remote is TX-2B .Plz guide me i really wanna complete this project.............:(:(:(

Computer Controlled RC Car with Wireless Camera

Hi

I wanna a project for my studies...

here is what i would like to make..

1. A RC Car that is controlled via computer and not by the its remote. i wanna create a application that controls the car and also displays real time video.

2. I wanna use zigbee (XBEE pro) for transmitting and receving commands and controls.

3. Wanna use mobile phone (wifi) camera for video transmission.

 

now i wanna know How can make this ???

1. which microcontroller should i use ????

2. which software should i use to make the compuetr app.

Routerbot (Without hacking the router)

I am intending to build a routerbot. This is my design idea. This is my first major robot so please comment and suggest if even the slightest urge arises.

I will call the robot flat friday.
