It had to happen eventually. I have never been under any illusion that the Robomower would be, in fact, a a maintenance-free device. With all the rattling and shaking going on, something was bound to come loose. Just as I might have suspected, the first part to go was what I had always considered . . . → Read More: Robomower part 12 – Things start breaking, and I’m famous!

Something awful has happened to the Robomower! In an attempt to start getting my side yard under control for an upcoming patio project, the bot got high-centered on a dirt bump. The wheels were spinning frantically in a valiant attempt to un-stick themselves, but succeeded only in churning up a gigantic cloud of dust. . . . → Read More: Robomower part 11 – On motors and their control… After some careful consideration, I’ve decided to just go ahead and start building something. I’ve got most of the stuff around, so If I have a serious change of heart, I’ll toss it and start over. After finding a couple of clamp lamps left over from a precious model railroading project that I abandoned, . . . → Read More: Book Scanner 2: Basic design elements… For the last several years I’ve been struggling with finding a method to get printed material into digital form. Of course, like everyone else, I’d much rather read books and magazines in their original paper format. That’s great, until you start spending more than a dozen days a month on the road. When that . . . → Read More: Book Scanner 1: Define the mission. It has now all come together! One last trip to radio shack to get some connectors, heating up the soldering gun to splice together some 24 volt wires and some ground wires, applying some Velcro, a few more wood screws, and I’ve got a lawn mower! After the successful test of the mower . . . → Read More: Robomower Part 10: It all comes together! This is the home stretch! The robot moves, it has a lawn mowing attachment hanging beneath it, and if I go out and actually hook the wires from the mower motors to the bot’s batteries, it will actually mow the lawn. Trouble is, since it’s an electric mower, I really want to be able . . . → Read More: Robomower Part 9: Turning on the mower attachment. This has been a long time coming. Over the last couple of years, it turns out that I have seen an increase in the time I have available to devote to projects that involve building things. I’m not entirely sure how this came to be, but I’m sure not going to raise a serious . . . → Read More: The CNC table – First thoughts and musings… A couple of posts ago, I promised a reciprocating saw. Today I discovered that somewhere in that whole “Measure Twice, Cut Once” thing, I seem to have missed something: The mower deck was just a bit too long to fit within the length of the frame. The way I saw it, I had couple . . . → Read More: Robomower Part 8 – Mowing something… Today turned out to be a good day. Despite daytime temperatures in the mid to high 90′s (roughly 20 degrees f above my personal cranky threshold), I made some significant progress. It sure seemed like most of what I did was just sitting in the hot sun, and all I got done was to . . . → Read More: Robomower part 7 – It’s Alive! This is getting fun! Putting the frame together is, for me anyway, a very important part of any project. Up until this point, the Robomower has been a stack of angle iron, a box of electronic bits, a crate full of wheelchair parts, and a rather daunting pile of random-looking fasteners. Today that will . . . → Read More: Robomower part 6 – Assembling the frame |
