Robot Track System Lawn Mower Build Pt: 2

First test run of RC Tracked Mower

A 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":

Everything powered up ok and so I took it out for a little test run...

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...


  1. Hi! nice post. Well what can I say is that these is an interesting and very informative topic. Thanks for sharing.Packaging Equipment

  2. I will say this is wonderful. Please say a few words about the track system. Did you build it? How? Did you buy it? Where? Thanks, bc

  3. Put a power wheels body on it๐Ÿ˜†

News from the Maker Desk
Happy Monday to you... hope you are doing great today; wanted to share something that was on my heart this morning about MakerGeeks and what’s going on and what the next steps are for us.

Almost 3 years ago we started selling 3D Printer filament(all of it from China) and over the next 2 years saw a booming business come out of those items; reselling filaments from China, Germany and the Netherlands. About a year and a half ago we started with a single extruder and a dream to start making 3D printer filament in bulk scale here on US soil… back then I thought that 1 extruder and me working part time would make more filament than I could sell in a life-time. Well, within just a few months we had bought another extrusion line and hired our first full time operator just to keep up with demand.

Now, surly we would have enough filament to last a life-time; NOPE… in just a few more months we added another extrusion line and lots and lots of overtime and weekends. Now we…
