Tired of building projects that need a programmer for the microcontroller and data books for all the chips. Why not keep it simple? That is what Hubert did when he built these two robots. A plywood chassis is equipped with the cutting motor attached to a standard (in Europe) 310 mm metal sawblade: you can easily find another one and change it if break down. There are 4 x 12 V reductor motors, each one equipped with a children toy wheel. An internal 12V 2Ah NiCd rechargeable battery power it. A front bumper (in wood and gray plastic) can move and actuate 2 switches: when robots meets an obstacle, it can avoid it. Hard to program microprocessor? complex computer? No! just few relays: simple and no bugs!” There are 2 x 12V DC motors, each one attached to one wheel. There are also rechargeable batteries, a plug and some components for charging, a (brown) plastic box to receive a normal standard sponge. Another translucid plastic box to receive water and liquid soap (empty on the picture). The 2 boxes (glued) are connected together through a hole partially closed with a screw in such a way soap water pour drop by drop to the sponge.”

Does the CD have the install software for it to clean your PC too?
Maybe I can use the mop bot after my roomba died

I like the lawnmower….but it doesnt stand a chance against my yard. The neighbor kids always leave shoes and toys in the yard. I fail to see how they have any shoes left.

I really like that lawnmower idea. I’ve got a fenced-in back yard that is pretty small, so something like this might make a neat project. If you were willing to do a bit of microcontroller work, you could make the unit stop and start automatically when the batteries are discharged/charged and also add-in a tilt sensor cutoff (in case it’s picked-up), etc. In my case, if I built it waterproof with auto charging control, I could just leave it in the backyard all the time doing its thing. My kind of yardwork!!

Nice work!!

I had to laugh, because historically the first bug was a moth trapped in a relay
