Matching rc receiver to power chair joystick control

A new wrinkle popped up while trying to test an interface idea between an rc receiver and power chair joystick control. Pin 8 is a switch output that's not connected unless there is a switch. Since the power chair has a feature that locks/unlocks the wheels to the motors and throws an error (flashing power lights) when wheels are disengaged I'm guessing that's the switch. The switch (if there) should be connected between pin 1 (+v) and pin 8 (switch output). So with the switch in the error state (open or closed, don't know) pin 8 would be ???

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.

Bluetooth on Smartphones PLUS and Xbee receiver on Robot


I have a another Question for all of you guys :D


Q: CAN I Control via Blutooth on SmartPhones using Xbee Reciever on Arduino Robot...,? 

OR it is POSSIBLE to Control the Xbee on Robot via Bluetooth on SmartPHONES...,?

If It can be,..., HOW ? and please Help me by Teaching me about it :D


Please Answer Prayer :D 

Update: Added new video. What if your robot is stucked and can't free itself?    Take back the control and steer your robot out of trouble. What if some danger … Read more

How to hook a actuator up to a servo.?

Im currently building a remote control snow plow, yes it sounds crazy, but very cool. Right now im trying to figure out a way to lift the plow up and down. I have an actuator from an electric wheelchair. my issue is how do i hook it up to the servo so it can be remote opperated! 

Thank you for your help!!

Experimental RC Robotic Hand

Introducing my Experimental RC Robotic Hand. I'm going to use it for a robot that I will use to take on Ro-bot-X's "Search And Rescue" Challenge. It's purpose is to get a hold on the drink, obviously. This is only Version 0.2, I'm am currently building a lighter and easier to use grabber to replace the heavier hand that is attached to the winch motor.  More updates soon.

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 

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

floor cleaning

I am no robotics pro, but have an idea that has merit in my work. I want to build a bot, likely based on a heavy "battlebot" off the shelf chassis. This will be mounted with rotor swinging "swiffer" or similar treated dusters. The idea is to automate dust mopping of very large floor areas in a nuclear power plant, and possible adapt the machine to decontaminate radiologically dirty areas.

Ideas for a remote controlled actuator with some limitations


A friend of mine is biologist and needs to capture regularly ducks to control their health.

He has made a jail which door can be released easily (guillotine door), but this jail is going to be placed on a platform in the middle of a small lake. He has asked for my help to build a device to remotely close the door.

Our first idea was a Hobby remote controller and receiver to activate a servo to close the door.

But there are some limitations which worries us:

'Axe as RC speed controller

Would it be possible to connect the output from a RC reciever to the digital input of a pcaxe 28x1 board and controll the motor outputs?

Of course it's doable, that's not really the question. But does anybody have any thought regarding it? Has anybody done it? I presume the signal out from the RC reciever is a standard Servo-signal. I know CtCpassed a signal from a RC reciever through his 28x1, but I don't wanna controll servos,I wanna controll a couple of DC motors.



This is my first attempt to make a custom remote controller, and also my first customized Arduino.
After seeing this post made by ObbBot I wanted to try to make one myself.

I figured that if I purchase one remote controller it would be cheaper than buying two of these and paying shipment to Portugal.

So, ripping the guts from a game remote controller I get two joysticks, a couple of buttons, two nice motors and one small lcd.
