Hi to all, im a new member of this forum. Sorry for my english but im italian, i come in this forum beacuse there arent italian robots forum.
Im build a robot, i have 2 motor of a wheelchair, i want to build the speed control.
someone can explain to me how to build it.
thx
In English:
Not trying to offend you but building a speed controler for a heavyweight is very difficult unless you just want on and off control.
Unless you are an electronic engineer I would not try to build a proportional speed controler.
Here is an on off reverse speed controler diagram by bugs:

Ed in italiano
Sta provando ad offenderlo ma sviluppando un controler di velocit per un heavyweight molto difficile a meno che desideriate appena il controllo avanti/stop.
A meno che siate un assistente tecnico elettronico non proverei a costruire un proporzionale accelero il controler.
Qui ¨ sopra fuori dello schema dinversione del controler di velocit dagli Bugs: http://www.bugs.nl/media/source/projects/speedo/relay-layout.jpghttp://www.bugs.nl/media/source/proj...lay-layout.jpg

Ian Mc Donald.
would a speed controller relying on a servo and microswitches pass a tech check?
hear my latest efforts to develop a speed controller http://www.chompalot.co.uk/motorcont1.htmwww.chompalot.co.uk/motorcont1.htm
Si
You could try ...

They might be generous and give you a couple.:)
Or purchase some from http://www.technobots.co.uk/en-gb/dept_68.htmlhttp://www.technobots.co.uk/en-gb/dept_68.html
As long as you use a failsafe on the servo a relay drive system will pass the techcheck. Ive seen several fethers and heavys running on relays.
thx very much.
It is possible construct a circuit to connected directly to the receiver, to creat an on off reverse speed control??
Just use a servo such as this:

That is what the white cross represents. You will also need one of these on each servo:

Fredrico have a look at this thread...

Have a look at the middleweight section. My idea to use the original wheelchair controllers worked by servos was best, of course.
can you give me the link or the name of your discussion thx
