i have in mind a slave position by turning 2 drive motors on or off using mdifferent speed settings to position slave from lnown position to where work is to...
... That is correct. I'm a member of several Yahoo groups and to read the emails (9 in 10 are usually of no interest) would be a real pain. ... That is what...
Just to show you what you're up against. http://www.youtube.com/watch?v=N2fp6apH5Rw This is the 2005 All-Japan champion. That first fast looking run... that's...
Anyone know of a long range IR detector, maybe 6-8 ft range, something similiar to what's used in TV ? The PNA4602 and the IS471F don't seem to be adequate for...
Quite worring about what the Japanese are doing. Me will never see one of those robots in real life. Since history has a very strong tendancy of repeating...
I am working on a robot project where I have a DC motor (12VDC and 30A max) that is being driven by a PWM speed controller in the forward and reverse...
If the IR is not pulsed at a set freq, then the range is cut back greatly. Using pulsed IR will let the detector tell the diff between background IR and a real...
LOL, Switch to a 'sevcon' motor controller and use your current one on another project. That would be the easy way. Your second option is to use an IGBT but...
I suppose a couple points I should have included was that I have to do the switching on the motor side, not the power side, because this is being done to 2+...
A 12v DC motor, that draws 30 amps. That's a big motor, you must be building a big robot. Are you using only one motor? You must be powering it with a car ...
Rich, I completely agree with you. The Japanese do set the bar when it comes to robots across the board. But, from past experience, people get discouraged and...
My suggestion --- take apart something that had an IR remote control (the control too, o'course). Then you know you have the parts you want, they are matched,...

what about making robots for fun? i plan to do robo-one in japan next year . . . i probably wont stand a chance my first year or two doing it . . . but i dont...

Strangely, I thought to look up Micromouse on Youtube the other day as well. That's the kind of stuff I expect my team to be going up against, but we're going...
... I've already started my micromouse design. I probably won't have anything like those zippy little ones on YouTube but that sort of thing hasn't stopped me...
There is no way to do this cheap. But there is a way. Replace the relays you are using now. Go with this. http://www.acroname.com/robotics/parts/R133-MD03.html...
hi. i have a motor that runs on 24v dc to turn the wheels. if i apply 24 v across the circuit, would it fry some of the components? if it would,could you tell...
check the datasheets for the maximum voltage rating for each component you think will fry =P typically most are rated for no more than 20V . . . ... -- John...

If you apply 24V to a 10V rated component, it will fry (and sometimes explode into pretty sparks). As for the amperage on the motor, you must look up the...

You need what is called a "motor controller" which acts as a bridge between the low voltage main controller (your robots brain) and the high voltage motors. If...
