The motor controller is a Curtis 1204. There is a hobby aviation remote control with a receiver onboard the ET. The servos control the steering via an electric motor and a belt driven pulley attached to the steering column. The throttle is a combined servo motor and pot probably from the volume control of home stereo. The forward and reverse are simply relay controlled. The steering wheel is absent and has been replaced with an old joystick. Fly by wire! You can switch between manual and radio control via a toggle on the dash. Even the mower power can be switched on remotely. Power comes from three large format Optimas.
The last owner attached a large video camcorder on it with a transmitter to his computer and he'd mow his grass from his office. He also used the remote to do it from the porch swing. What else would a retired electrical engineer do for fun?
I was having serious noise issues with the remote which I have not solved yet so the radio control is not in use currently. She used to go nuts randomly. I think the controller battery was dead. I might try to get the radio control working again this spring if I have some time.

I have a box of parts do that with one of my e15s. Part of the point of the exercise would be to make it dual-mode: either drive it by remote or from the seat (as usual) with no hassle to switch modes. And I guess a guy should lock up the r/c transmitter if he's got wise-acre kids...On Sun, Mar 7, 2010 at 4:13 PM, Jeffrey Tickner <jeff tickner gmail com > wrote:On Mar 7, 2010, at 12:00 PM, elec-trak-request cosmos phy tufts edu wrote:> > > I think we could make our ETs do this. > > http://www.youtube.com/watch_popup?v=tPg1ZMiC9pA > > > Imagine plowing or blowing snow from the warmth of your house! > Or cutting your lawn while setting in an air conditioned room. > > Ralph VoganThere was a group at a university that used an elec-trak for a robot chassis. just takes money and time._______________________________________________ Elec-trak mailing list Elec-trak cosmos phy tufts edu https://cosmos.phy.tufts.edu/mailman/listinfo/elec-trak _______________________________________________ Elec-trak mailing list Elec-trak cosmos phy tufts edu https://cosmos.phy.tufts.edu/mailman/listinfo/elec-trak
