Robot Track System Lawn Mower Build Pt: 3

Lost 100lbs of ugly FAT Those big 'ol batteries were heavy and ugly and had to GO... so I found some very nice smaller deep-cycle AMG batteries that still have 22ah and weight about 100lbs less... whew, now robo-mower is running mean and lean.
Check it out:


Next up is paint and the electronics box... almost there!!

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 t…

Robot Track System Lawn Mower Build Pt: 1

RoBO Lawn-Mower So, I work at our church on the grounds team and my job is to use a push mower on the VERY steep hills around the main building; I would say there is about 2 acres of this extreme hills that need to be mowed every week. Whew... it's pretty rough sometimes!! Of course my inner-geek always comes out while I'm mowing and I think of how I could make it easier... well, what about having a robot do this for me!!

But what sort of robot could manage these hills and do a GOOD JOB of cutting God's grass... hummm...

I have been doodleing and drawing for about 6 months on this and finally started building last week!!

Here we go...



I had a small push mower that I had just bought so I was going to use that for my platform and started researching what sort of motors are best for robots and battle robots; and found that wheelchair motors are awesome work horses.

I found some on eBay for the Jazzy Pride 1 wheelchair, perfect!! I also found …

the MakerGeeks.com Story - "Make Happy!"

the MakerGeeks.com story
"Make Happy"Hello, my name is Joshua b Smith and I own MakerGeeks.com -MakerGeeks.com was born out of a hobby that got way out of hand. I have always been interested in building and making and about 3 years ago I got hooked on Arduino® programming and building and flying home-made quad-copters. On a forum that I was a member of for the Aero-Quad group I met some great people and one of them got me interested in 3D Printing - we talked a lot about what makes a good 3D Printer and over the months I decided to make a Mendel90 RepRap machine from scratch. I wanted to source all my own parts so I could build the machine from the ground up and have some ownership in the design. After about 6 months of building and tinkering I was HOOKED, OK... beyond hooked actually and I wanted to be able to share this new passion with others - and... OK, the truth is I just wanted to have an excuse to 3D Print everyday and talk to others that are into the s…
