Sensorized harvester headStarting point
• Simple structures• Low request of power• Smaller prime mover required• As first prototype, looks more suitable for SLOPE pur-
poses• Furthermore it looks easier to extract branch para-
meter, working on variation of pressure on the stroke hydraulic cylinder

Sensorized harvester headDesign of the novel subsystem
Scan bar for NIR camera and hyperspectral imaging
Hyperspectral and NIR sensors will be positioned on a lifting/lowering bar (so called scan bar) parallel to the chainsaw bar and placed in a separated carter for
protection from dirty, lubricating oil and chipping
Sensors need specific and very small distance (~ 3 mm) from log surface
Velocity profile of scan bar need to be defined
