Team MCS Robotics

[rallikas]

So lots of people are making their own topics, where all the stuff is together, im gonna make one too, just to keeb everyting in one place/organized.
All of the information about building and stuff will be here.
So lets begin.

So, there is a little turtorial/overview how to make a high powered servo from any geared motor- Cheap.

Re: Team MCS Robotics

hmm i might try making a similar controller for 360s self-righter.... you seem to have two servo boards in the electrical box uve made, why is that?

It looks like your just using the two motor outputs from the servo to fire 2 relays.. one forward and one reverse... correct?

[rallikas]

Re: Team MCS Robotics

Yes there are 2 servo boards, but i use only one. (amother one is just for another servo)
I used the same control box on my full size rc car, so it has some more channels...

You need only two relays, 4 diodes and 1 servo for one superservo. Look at the schematics in the video.

So here is how it works.

Re: Team MCS Robotics

That's really cool
Didn't realise you could make an electric motor servo in such a simple way.

Q: Just out of interest, how have you attached the end of the potentiometer to the output shaft of the gearbox?

Do you actually watch the videos too, or my english is too bad?

Yes, the shaft comes out from both sides, end of the potentiometer is shrink-tubed to the shaft.

Re: Team MCS Robotics

I did watch the videos, but I couldn't make out anything about how the potentiometer was attached. Now I know though

Re: Team MCS Robotics

sweet, etek powered servo here i come

Re: Team MCS Robotics

That thing will cut your arm off ! (just had to say it)

Re: Team MCS Robotics

Updates!
Made some pics from the last robot project i have been working on.
Have done some test drives too, it isnt the fastest thing that i have made, but its enough for a spinner!
Quess what the wheels actually are made for!



These bent brackets in the front are only temporary...

Re: Team MCS Robotics

guessing...er...no clue, are they rollers for conveyer belts of some kind or something? :P

Looks great though, I like the design so far.

Re: Team MCS Robotics

Ah it's been too long since I built a robot using windscreen wiper motors, seeing these pictures makes me want to make one again

Nice work Mart.
I, like Joey, have no idea what those wheels were originally for so I, like Joey, am going to go with some sort of belt conveyor :P

Re: Team MCS Robotics

Actually these are rubber boat rollers!

Re: Team MCS Robotics

I used windscreen wiper motors for my first robot but untill I tested it I did not know that they go fast one way and slow the other. :blush: so my robot was very slow and it was very hard to go in a straight line.

Re: Team MCS Robotics

Pretty good mate.

Another 6 more robots and youll have an army :P

If you look at my robot, u see, that i put the motors in the robot so that they spin in the same direction, so the speed is same. Transmisson is geared up too. 24t sprocket on wiper motor and 12t on the axle.
