@o_lampe Thank you for this idea !
Yes, I would like using only one motor with a chain, cause even if the ground it's not perfect, it will planting very slowly.
I imagine this more like a semi-automatic transplanter, so I will be close to it to drive him by hand.

@infiniteloop Thank you for the details ! I will try this soon !
In fact, I think it will be a "semi-automatic" robot, I will drive him manually during the planting session, but I'm working on permanents beds so it's quite straight

@droftarts Thank you for your reply !
I was thinking of doing something like that. Thanks !

Hi everybody !

I'm a french market farmer, and I'm working on a small "robot" tool for transplanting vegetables on my farm.
I have a Duet 2 Maestro card that I would like to use for creating this, because I think it's more reliable and easy to program than others devices.
I would like make 3 movements with this robots : 1 on the Z axis to up and down the plants, 1 on the Y axis to create a "charger" which contains all of the plants plugs falling down into the Z axis, and 1 on the X axis to move 30cm diameter wheels... for moving the robot on my land (to transplant every 15cm for example).

By reading the Duet documentation, and because the robot will be heavy (maybe 40 kg to move), I understand that I can't use the x-axis stepper motor traditionnal PIN on the board because the voltage, the wheels and the weight needs more powerful DC motors than a NEMA 17. I would like to use this kind of motor

So my question is : the documentation mentioned that it's possible to wire DC motors on the heating bed PIN. Do you think it's possible to wire this 2 wires DC motor directly to the card for moving wheels and robot, and controlled by the Duet card, without burn it ? Or do I need an expansion card to control it ?

Thank you for your help, and if you have another ideas, don't hesitate !
