motor controller

SOLUTION TO CONTROL 10 MOTORS WITH ENCODERS (OPTIONAL?).

6 MOTORS TO DRIVE THE ROBOT.
4 MICRO MOTORS TO PIVOT THE WHEELS.

PARTS LIST:

1. Arduino Mega 2560
2.
3.
4.
5.

I just got hold of OddBot's Rover 5 platform and the 4-Channel Motor Controller.  I'm still fairly new to all this and I'm not sure what PWM frequency to use for the controller.  The datasheet that I have doesn't specify so I'd appreciate any advice you can give me.

Many thanks.

I have been flumoxed by a motor issue recently, and was wondering if others had some strategy dealing with it successfully.

hi,

the weight of my robot is 12-14kg.....i am having a serious problem in selecting motors...

motors must must have good rpm

must have torque 

must  have feedback (for differential drive , positioning and controlling)

must have power to drive 12-14kg.....

plz provide me guidance.......... 

CTC & I were shouting and the topic came to smart motor control.  Strangely, I have was working on a motor control software interface, and thought, what a great opportunity to ask, "What would you desire in motor control?"

My interface commands currently looks like this :

I'm trying to control two motors  by means of a joystick. This means I've coupled the potentiometers inside the joystick to my Picaxe 28X1 and my Picaxe 28X1 to two MD03 motor controllers. 

While testing I'm using only one potentiometer and one MD03. The problem is that I cannot get the system to work.

The program I'm using right now is:

i2cslave %10110000, i2cfast,i2cbyte

main:

readadc 0,b0

Hi,

I am using a sabertooth 2x10 motor controller in my tank style robot. I have been controllong it with a PIC microcontroller board and all has been going well. Until the other day when i was using it and the status1 LED went off and the board stopped working. When i power it up now, all the motor outputs are at 13V and the status1 LED stays off. I have taken the heat sinks off the board and inspected the components but all looks ok.

In desperate need of help.Does anyone have experience of this problem? All help greatly appreciated!

look ,iknow it`s a stupid question ,but i want to know waht is the motor controller? ,and what is its use?

replies please ...... 

Hey everyone. I am building a couple of projects using electric wheel chair motors. I am using the Dimension Engineering Sabertooth 2x25 motor controller. The proble I have is I am sending pulses of 1000, 1500, & 2000 us to the sabertooth and am getting random results (both forward, one forward the other reverse, both fast, both slow, one fast & one slow, etc) with no apparent consistency.

Update!  I answered my own question....I found that this motor controller has a max PWM of 127 not 255.  Once I changed that, I was okay!

HI Guys,

Hi all, i'm wondering how i can control a motor with 2A current flow at 6Volts. I'm hacking a toy and the motors that make it to move requires that current... so i can't proceed to my plan A: the L293DNE, because it manages a maximum of 1.4A.

I don't know if exist a similar chip but wiht a higer current limit.

If You have ideas for that... PLEASE HELP ME!

Hello guys. I'm creating a RF controlled 2.5kg sumo bot. I'm a mechanical engg. student and so don't have much knowledge in electronics.

Basically I need to create a 10Amp motor driver for driving 2 12V dc motors,10A each using relays.
Buttons on remote control:

      1
2           3
      4

1-Move Forward
2-Rotate Anticlockwise
3-Rotate Clockwise
4-Reverse


I'm planning to use these schematics for radio controlling

Hey folks.

 Becausse the PICAXE kit already ships with all the components (er, most of it) glued, I wanted something more challenging. So, I am trying to build my robotic brains from scratch. 

Whilst I have come across quite a few (video) tutorials with circuit diagrams using PIC microcontrollers, I am not able to use a motor controller. One such is here: http://www.seattlerobotics.org/encoder/200001/simplemotor.htm. 

Hi, new to these forums and hoping someone can help me out!

I'm building a robot submarine (ROV) for fun on a pretty tight budget. The robot will have an on-board PC (in the form of a micro-ATX or nano-ATX motherboard) and will be controlled down a tether wire.

I need a little help with my Pololu Micro Dual Serial Motor Controller.... I am trying to use it with my arduino robot but I have no clue where to start code wise  ... where can I get sample code ... or even a guide on how to code for it .. I am sort of stuck on  this .... any help is appreciated greatly :)

Hi

I'm building a robot based on my old RC-car and an arduino. The motor-control in my cars is "mechanical" where a servo switches the motor on/off etc. I would like an electronic motor-control instead...and i'm pretty lost.

Do you know a simple motor-control that will make the motor go forward,  just for a start? ;)

I think my motor draws a lot current so L293D is out of question..

I am researching motor controllers and am looking to try something new. Previously I have used the Dimension Engineering Sabertooth 2x5 and am looking for something in the same ballpark.

The controller will interface with a PICAXE 40x. So please feel free to shoot me some suggestions.

Thanks,

David

When writing this, LMR only offers "Start here" - instructions on how to make your first robot, using Picaxe.

"Nebster" wrote to me, and asked if I could do a parallel, using Arduino, and I think that is actually a very good idea (now that Picaxe refuses to pay me commission, haha)

Focus should be on making first timers get a robot up and running at a low cost, and most importantly learn how to hook up motors, a servo, and a analogue input in "no time".
