Denna L600 test

 Okay...some test pictures :)

 I mounted charging station and perimeter wire as per manual...cca 100m wire used for first attempt.

 Mower in action...

 First problem...and solution for problem :)...worst part of denna mower is bumper, in middle,

where are the charging contacts, bumper sensitivity is small-or useless, so when mower hit the tree direct in the middle of bumper there is no action at all...resulting an error message... and then you must manual restart the  mower.

I had just few days for test...tracking the  perimeter wire is perfect...charging...return to base station is perfect...but that bumper :(

So...I need some better solution for front bumper, Ardumower bumper is the solution....

Soon some more tests...sadly...no time...

Denna L600 robotmower...repair...test and some pictures

For now - only few pictures....

I bought two  dead denna L600 robot mowers cheaply...

Main idea was to convert one to Ardumower , and one to left  for spares....but i managed to repair both mowers with minimum efforts...

We have in Serbia  house with big garden-and since we are now in Austria -mowing grass in our garden  is the biggest problem :), for my old father :)...so I hope to resolve this problem with robotmower.
Sadly they are not cheap at all...Husqvarna, Robomow...Honda Mio and others leading manufacturers  are superb, but I don't have 1000-2000eur for high end machine...

I will perform some test soon-in real life, with original Denna electronics, and soon I hope with Ardumower electronics too...

 Main cpu-too small :)

 Coils for perimeter wire tracking.

 On one  Denna  elektronics charging mosfet was  shorted...on other Denna problem was
 slippery wheels driving shafts, and corroded charging contacts.

 L298 motor drivers...one for each motor

 433MHz RX for remote controller

 Sadly, no info-schematics about circuit on web....

 Mower motor

 Two main motors...

Wiring inside mower....
