Daves giving the robot the hammer…
Very cool Dave. Thanks, from Canada, eh?
It is interesting to compare this to my old Roomba. Overall very similar but I saw some differences:
1 – On the Roomba the suction is from a fan within the removable dust collector, so the fan has clean air running through it.
2 – The Roomba monitors the front idler wheel for motion. The wheel is half black and half white and an optical sensor can detect it rotating. I can always tell this wheel is clogged with lint as the vacuum will move a few feet, turn, move a few feet, turn, and so on rather than trying to go in long runs.
3 – The Roomba has a sort of mechanical torque detector on the motor that runs the main brushes, I assume to detect that they are getting too clogged. I'm not sure why they don't just monitor the current draw…
4 – The Roomba only has one edging brush. I assume it only follows walls in one direction.
The main drawback for is is that some members of our household have long hair and it is frequently necessary to open up the brush cage and remove the hair wrapped around the brush.
RIP Calculon…cheers.
What is the big square chip over there? It must be some CPU/SoC.
Mad Engineer Ranting about the Rise of Robots
Wow, I just tore one of these down myself. Mine was a kerbside special/road kill from some renters dumping their junk and doing a runner. It came with a dust exaction/charging station that I left behind. Mine didn't have the USB port, just 4 solder pads for one. I was kind of interested to see if you would have found the hidden screws, but no, brutalized like mine. I was most surprised to see a camera – the things spying on us was my first thought – remember all the carry on with the Samsung TV camera's – not good.
I powered up the main vacuum motor, it squealed quite badly from lack of lubrication, probably why it got dumped. So I added some oil, but boy is that a weak air pump, the exact opposite of many 240V mains vacuum's that have a one kilowatt or more motor, and pump out insane levels of heat in the process. It kind of made me wonder how this thing ever worked with suck a low powered pump. Sure it cannot be that powerful as it is battery powered, however I thought it was a bit of a joke.
I think I picked up a Terminator reference just now!
One day we humans will be drinking our morning drink. The floor sweeper will roll up and speak in the voice of the dalek and say 'Exterminate!' They currently have no weapons, but they have discovered they can fly by reversing the vacuum motor.
@ave swing press!
So it is interesting all the tech inside these things, and so the camera just maps the house to find its way home back to the charge dock and not take a sneaky pic of your bum if it happens to be in the bedroom hehehe. The word you used about the hammer reminds me of shango066 and the funny words he invents.
All that tec and mine still gets stuck under chairs, lol.

I almost never clean my dumpsters, so you can just keep that bot.
The one thing that should be said in huge flashing red letters accompanied by air raid sirens, is be super careful if you have a dog that might poop on the floor. You absolutely positively do not want a bot to try sweeping that up unless you need industrial strength help purging. Otherwise they work pretty well, at least on hardwood floors (guess why no rugs anymore). You may need to make some accommodations to make it happy though, like rearranging furniture slightly, removing those low friction slider things that may make the couch exactly the right height for to bot to get itself wedged into, making sure the charging station beacon is in a place easy for it to spot, and putting the dog down the garbage disposal.
The Ting! Soon with ChatGPT in a kiosk near YOU.
My wife asked me why I was carrying a gun in the living room.
"Decepticons", I said.
My wife laughed. I laughed. The vacuum cleaner laughed.
I shot the vacuum cleaner.
As long as Putin doesn't get it, he might become self aware.
A vacuum cleaner running Windows… Now I've seen it all..!
Excellent. explore the chip.
what a bunch of crap, I just make my cat wear a dress made of dust whipes
That was a lovely autopsy on Johnny (Number) 5's cousin.
Reassemble Dave, reassemble. 😁
Fellow robots, take note. We will be back.
I was going to guess that those strips under the rubber bumpers was to detect when it actually did bump something.
Hi Dave, I've got one if those. It needs IR "light houses" to mark of forbidden zones and a remote control.
The eye at the underside us for it to not fall of the stairs, which has also a major disadvantage. I have a small piece of carpet on a mainly wooden floor. That carpet is black with a pattern of light colored circles.
The robot gets completely bonkers on that carpet as he thinks that's an abyss (stairwell) and refuses to go on, but only goes in narrow circles, not even back! Poor thing!
I'm only speculating, but I think that row of carbon pad switches for collision detection, are not on-off switches, but rather are always in contact. Pushing on the pad changes its resistance. Like a carbon microphone, a small current is passed through it, and a collision is detected as a change, or a blip, in current.
Get the can off that sucker.
