Design in Progress

Info

We need to move away from being dependent on Vention products, this will be a clean sheet design:

  • They are not compatible with other similar parts and are often discontinued.

  • Limited choices are causing sub-optimal design decisions.

  • Existing gantry is limited in width, the optimal solution is a gantry that is the width of the entire plot, thus eliminating the need for turning / complex navigation systems.

  • We have decided to use the Farm-ng Amiga robot as the base power unit for BB 3.0

Summary

Description

Allowable Limits

Status

Axis of Movement

Shall provide 3 integrated axis of movement X, Y, Z.
Y axis movement will be accomplished by the Amiga robot via powered wheels in contact with the operating surface.
X & Z Shall be accomplished with a gantry system.

True

Draft

Tool Head

Shall provide standard electrical & mechanical interface for mounting a toolhead (such as a camera or actuator).

Draft

Tool Head Positioning Range

Shall be capable of positioning the tool head anywhere in an operating envelope defined by X, Y, Z dimensions offset by minimum or maximum height from the operating surface.

True

Draft

Tool Head Position Accuracy

Shall be capable of positioning the toolhead in the operating envelope to this degree of accuracy.

1cm > PA

Draft

Tool Head Mass

Shall be capable of supporting a tool head of at least this mass in all operating areas.

50kg < M

Draft

Assembly

Shall not require significant specialized labor to assemble onsite.

TreuTrue

Draft

Gantry Width Configurability

Gantry width shall be field configurable to a specified range without major design changes.

True

Draft

Min Configurable Gantry Width

Gantry shall be configurable and fully functional / structurally sound to at least this width.

W_max >=20'6m

Draft

Max Configurable Gantry Width

Gantry shall be configurable and fully functional / structurally sound to as little as this width.

W_min <=6'2m

Draft

Tracking Accuracy

The concept design is for a 20ft wide gantry, but it can be configured in many widths, definitely smaller and possibly larger with further engineering verification.
