DIY robot lawn mower

[Two-Stroke]

In your idea for a fast RC mower I would think something like the below platform could be made
to go real fast.

That looks like it could be pretty fast. I have three old reel push mowers in my basement -- but the idea isn't appealing.

but the idea isn't appealing.

I see no reason why a standard gas mowing deck couldn't be used in place of the Reel type.

I meant that using a reel mower was unappealing.

I like that little bot with two wide rubber tires but it looks expensive and if I do a remote-control mower it will be on the cheap.

 

[Tommy]

looks expensive

My best guess, if you had no RC gear, $1000Us. but with that said, I had set a budget of $2500Us
for the first stage of George, I can now see it more like $4000Us.

PS: I did waste @$600Us on unusable tech.

That is impressive. I have heard of manufacturing applications like that including the prediction that a lot of consumer products that have been mass produced will be custom made with tech like that in the not so distant future.

will be custom made with tech like that in the not so distant future.

After spending all day standing in front of a Milling machine and Lathe just to make two of the items
below for George, I kinda wish the future would get here.

Thanks for the update. Do you have access to a machine shop at work?

 

[Tommy]

Do you have access to a machine shop at work?

Yes, at the main office which is only 100miles from my place.

I got George home last night so I didn't get a chance to test the changes made.

It toke me two days to make and install, I sure it would help if I was a machinist.

In the "It looked good on paper" category. I had planed to have the chain/gears tucked up
inside the tire rim to help keep crap out of it, but with the gear sizes used, when the chain
is tight there was only 1/8 of an inch clearance between the chain and rim, and with the run-out
in the rim(cheap rim) I could see it hitting at some point.

George has a very heavy duty look to him, as I guess he must if he's required to push snow around.

Does George have suspension? I was a bit surprised to see the spring in the latest photo.

 

[Tommy]

Does George have suspension?

The springs are needed because of the DC motors which can generate full torque in
a faction of a second. when I first started programing the drive software and I got it
wrong it could go from full speed forward to full speed reverse in one second, without
the springs all my motor mount brackets would need to be much stronger.
