RC Lawnmower Explained

[allanonmage]

How do you control the brakes? I need to figure out how to implement the ones on mine. I was thinking of using a switch channel on my R/C transmitter. How could I make that activate a relay though??

[jimenezlee]

@allanonmage My design needed no brakes.  When the stick returned to center it would stop and the motors would offer resistance to movement. The Sidewinder controller did all this.

[allanonmage]

@jimenezlee It looks like they are still on there. Did you leave them as a dust cover? My setup stops as well, but I'd like to figure out a way to engage the remote from the R/C transmitter. Later on with an Arduino or the like I suspect it will be easy. DO you know how to take a servo output and control a relay? I have 2 switches on my R/C transmitter, so I suspect that it's capable of doing this, I just don't know how. Hobbyking has little to no documentation :-/

do any of u guys know if there is a subsitute for the sidewinder? 400 bucks is wayyyy too much money

[allanonmage]

@alecfederov91 I use a hobbyking TX & RX, it was around $30 new incl shipping.

[biggray94]

I have a remote I need help with wiring before I remove it from wheelchair

[biggray94]

i have my chair, mower and remote control, will be getting started soon may need some help

[jrocker74]

Why not start with a unit that has a rectifier regulator on it. Or add one. You could have cut the weight and cost of the Battery's in1/2 or better. And never had to charge the Deep cycles. Us a small Motorcycle battery there what 20 bucks at Walmart. Vers proly 300 bucks for the deep cycles.

[jimenezlee]

The deep cycles were also from Walmart at about $75 a piece. I did not put a generator on it as I was anxious to get it running. It would probably be a good idea to add one.

[jimenezlee]

Yes, pretty much the front part of the frame is the original chassis.
