Energy and power budgets

From a vehicular system perspective, at some point one has to think about how much power and daily energy will be generated, which will depend upon;

  • Solar array output rating
  • Location’s monthly average solar insolation (instead of simply latitude)
  • Cloud cover for the day

Then the power and energy budget can be roughly apportioned to individual subsystem components;

  • Electro-mechanical
    – Drive motors
    – Steering motors
    – Robotic arm(s) and tools
  • Electronic
    – Processing unit (including memory and storage)
    – Communications (GPS, and any of wifi, bt, etc)
    – Sensors (Camera)
  • Energy storage
    – Battery (if a small one is desired to smooth out frequent partly cloudy day dips, a medium size one to smooth out daily variation [start sooner, end later, etc])

The various use cases can have very different power budgets, such as weeding, planting, level ground vs. slope, etc, as well as different locations providing very different solar inputs (e.g., So. Cal vs. Vermont)

There is also the subject of modes, as it will invariably have at least two basic modes;

  • Operating: Able to move about, plant, cultivate, etc because sufficient power is being generated (or pulled from a battery, if so equipped). When sufficient power is no longer available (or when the battery reaches a predetermined discharge level), it transitions to Dormant.
  • Dormant: Awaiting the moment the morning’s sun will be sufficient to transition back to Operating mode (or when the pre-determined start time is reached, because a specific amount of charge was left in the battery to begin morning duties). In Dormant mode, it is either fully off, or in a very low power draw mode.

I’m used to larger fields with multi-row implements and bigger tractors, where weight, traction, and power are optimized to pull a planter or mechanical cultivator through the soil for each row.
800W is about 1 hp. How much pull force can you get from Acorn?
For example have you tried putting a single cultivator blade in the ground to see if Acorn can pull it?
