Perimeter wire with sensors for robotic mower

grint last edited by

Many of the robotic mowing options out there use a perimeter wire pegged down to define a boundary. Can the pegs be numbered and when a mower gets near the perimeter it senses (for example) Peg 3. How would
a} the individual pegs get their own identity
b} since they would be (shallowly) below soil how could a robotic mower identify them through the soil?
Thanks

@grint Nice topic!
But googling immediately led me to this site: http://www.ardumower.de/index.php/en/induktion
Seems quite easy to build yourself.

@Yveaux - hi - I've seen that and spoken to them, but they don't use the system with numbered pegs that I'm suggesting to get a clearer map of the robot's location. They simply use a perimeter wire. Their lane-by-lane mowing doesn't work very well, because... knowing where the robot is within the defined perimeter is pretty hard. Cheers,

@grint how would a compass sensor perform in a lawnmower robot?

I would really like to get OTA working here as it's freezing outside and I have to go there to update the software in the greenhouse control system. So please, can we have a 'how to' step-by-step guide to OTA? Please? S.

Hey guys, I was justing wondering, is there a way to deactivate the motion sensor if not being used? Eg: My motion sensors are connected to Homeseer and they show up as sensors but I was wondering if I could have an ON / OFF control to deactivate or active the motion as needed.

That's right @gohan , if you place the "door closed"reed near the floor then only first interrupt should matter, first interrupt should tell you the door is closed. Same for a second reed placed high - the "door open" reed, that would tell you the door is open when interrupted the first time. @McQueen, could be close to you needs ...

@gohan said in Arduino Pro Mini Shield for RFM69(H)W: If I remeber right that pin is used as input so the RFM69 is not receiving any 5v signal. In addition there are people claming they have the RFM69 module working on 5v on data pins and 3.3v on vcc, but I hardly suggest to do it. thank you just what i thought . about direct 5v on data...well... i seen a big red sign saying n :DONT do it! lol Level converters are so cheap...that i ordered 5 or 10 thoguether with rfm69 board. sorry about hijack this topic, i though i was on general discussion

@IronFelix I would not combine so many inputs and outputs in one sketch. But I think if there is enough memory for variables ; then it is possible to go for sensing (step by step) for a combination of sensors. Similarly for buttons, actuators, use a separate hardware.

@Serg2055 as the name says, openhardware.io is for open hardware. You are allowed to sell PCB units, partially or fully soldered boards, but selling source is not an acceptable option. Please include readable schematic and source of your boards or at least gerbers or bom. For all your boards posted on openhardware.io. Thank you !
