First test run of RC Tracked MowerA few more steps in the right direction today - removed the electronic brakes from the motors. The electro braking system must be supplied with a constant 24v to release or you can just remove them and save yourself that amp draw so that's what I choose to do.
Also, built my 2 battery boxes and bought two deepcell marine batteries today. These batteries are monsters, about 50lbs each so it's a lot of added weight and size that I wasn't counting on in the original specs however it'll work for now in testing - I'm sure I can find something better. One up shot of these batteries is they provide 109ah so at a 20amp draw I can get 5+ hours of use out of this big boy!!
Here are some update pictures:
And this is what 100lbs of lead and acid look like.... This just rubs me all sorts of ways bad, I hate building ugly machines, and with those batteries it's just UGLY!! There is a better option out there I know it!!!
I'm using the Sabertooth 2x25 micro-controller H-Bridge system along with my VERY OLD Fubata 72mhz 7 channel radio. Here is the wiring setup, please note this is all still in just "slap it on, testing mode":
Working great... So my hit list for now is to get some rust prohibitor paint on , I need to remount the motors using lock-tight on the bolts and then I also need to sort out this battery issue. I would like to get the batteries down to something MUCH smaller and lighter and if I could get about 1-2 hours of runtime that would be great.
I also need to work on getting a one wire alternator/ generator for the mower so that while its under power it can recharge the battery bank, I'll also need to build some-sort of battery tender or minder to monitor voltage and only charge when needed; maybe an Arduino circuit would be the way to go on that one.
Also, would like to fit the bot with a small FPV camera and 5.8ghz camera system so I can monitor mowing from a remote location.
That's all for now, more to come...
