My Persistent Brain - Rover 5

This blog entry is my persistent auxillary brain for robotics stuff.

Motors:

Can't generally run a DC Motor from an Arduino because motors draw too much current and it would fry the board.  So the Arduino needs to provide logic controlling an external power supply.

different versions of dagu controller behave differently?

Hi,

I posted this yesterday in someone else's thread and was advised to start a new one.  My message from yesterday:

This is my first post, so forgive me if I break protocol.  I bought a rover 5 and then bought a dagu 4 channel controller from a british outfit (robosavvy) and was able to create my first robot.  Super cool!

Bad things happen

 

Now that i got my new battery(8.4v 1000mah, down below), my bluetooth receiver for my "controller" died. Now i have to get another one.

 

Android phone as a controller

Hello there :)

I'm on the edge of purchasing an android phone. Looking at specifications around i thought: "Hey but this is the perfect controller for a robot!!" It has an incredible inventory of useful stuff: gps, compass for navigation, wifi, bluetooth and cellular for communication, huge screens for UI, speaker for talking, plenty of cpu, camera, easily programmable, and so on, all packed in a small package, all low power! And all for as less as $200! What do you want more ??

There's only a drawback: there's no simple way to phisically connect a device to peripherals :(

Drive system

Hi guys!

In my everlasting search for... well, basically anything interesting on the interweb, I've come across the RD02 drive system. This is a pretty powerfull motorcontroller, packaged with 2 encoded motors.

Some random features are:

An Arduino and a Playstation 1 Controller

I'm having trouble interfacing a playstation 1 controller with the arduino. the project will eventually be to use it  wirelessly to control a simple robot.

I was wondering if anyone has actually gotten the PSX Library on the arduino website to work and if so how, even if it turns an led on and off.

here are some links

20Amp Motor Driver/Controller

I am looking for a 20 amp motor controller/driver. I prefer an IC, that way I can integrate my own driver circuitry, but if it is cheap (under 50) post it. I'd prefer if it could provide 20 amps per channel. It will be operating on 12VDC.

Servo controller using timeframes

I have four servos with the following specs:

 

What digital servo uses a Atmel 168 internally?

Several months ago I read a post on LMR about a digital servo that was controlled by a Atmel 168. Now when I say controlled, I don't mean hooking a servo to a microcontroller the normal way, I mean the motor controller board inside the servo had a Amtel 168 chip on it.

Just to clarify - I'm not trying to figure out how to control a servo with a microcontroller (like an arduino). I'm looking for a servo that uses an atmel chip on the controller board inside the servo.

Controlling a DC Motor (Mabuchi FA-130)

Hello,

I'm trying to run a Mabuchi FA-130 (#18100) DC Motor, it uses 3V and 2.1A when stalled. However, I did some measures and when I forced the motor to stall it consumed nearly 4A, but I think this was some sort of coincidence since It has never happened again.

I'm using a circuit similar to this one posted by Simon Z in his post:

UGV Monster truck platform

I'm planning to build a UGV monster truck, based on a Tamiya Super Clodbuster. I've heard that it's a lot cheaper if you buy it in pieces. However, I ran into a bit of a dilemma. The stock monster truck comes with a speed controller. Do I need that too (I don't need any RC functions) or can a motor controller for Arduino or Basic Stamp do the job too. I already own a BS2 with BoE, but I would like to buy an Arduino because it's cheaper, open-source etc. Note: I'm still a beginner in robotics.

Led controller

Hi this is an led controller  there can only be one led on at a time it was on crocodileclips i don't know what its called but if anyone does that would be helpful. when A is high 0 is on if B is high 1 is on if A and B are high 2 is on and when A and C are high 3 is on or somthing like that.

Thanks,

Price: $40 USD

A Playstation controller as remote controller

So, suppose i have a couple of those wireless radio serial modules.. I'd like to hook the receiver to my robot, and install the transmitter on a playstation controller. Now, given that i can make a protocol of my own, the question is: how can i interface with the controller buttons&joysticks ? i'd like expecially to read the analogic joysticks.. is it hard ? How is it build inside ?
