3DOF-S300-50KG
FDR
For this project, we delivered a custom‑built 3‑DOF motion platform powered by servo electric cylinders.
Platform core specifications
Stroke: 300 mm
Max linear speed: 500 mm/s
Rated payload: 50 kg
Actuator type: Servo linear actuators (FDR065‑S300)
Auxiliary manual hand‑wheel for coarse vertical height adjustment
Dynamic movement matching real‑world farm undulation The three servo electric cylinders work in coordinated motion. The platform reproduces tilt and heave displacement that simulates the terrain fluctuation when the pruning machine travels along uneven tea ridges. The 300 mm effective stroke covers the full range of ground elevation changes normally found on hilly tea plantations. Running speed up to 500 mm/s faithfully replicates the working travelling speed of field pruning equipment.
50 kg payload capacity for complete cutter assembly The platform carries the whole pruning cutting‑bar mechanism. With 50 kg rated payload, it supports the full weight of mechanical cutting arms, drive motors and mounting frames, so testing is performed with real‑size end‑effectors rather than simplified lightweight prototypes.
Manual hand‑wheel pre‑adjustment for flexible setup An integrated hand‑wheel lifting mechanism allows technicians to manually set the base working height before starting automated dynamic tests. Operators can quickly shift baseline height for different tea‑tree varieties with different bush heights without modifying software parameters.
Servo closed‑loop control for repeatable test data All movements are controlled by closed‑loop servo drives. Every tilt and vertical displacement can be precisely repeated. Test runs are reproducible, which is essential when collecting comparison data for cutter‑path optimisation. This eliminates inconsistent results you get from manual field testing.
Typical Application
Dynamic attitude base for orchard & tea‑tree canopy pruning robots
Real‑time leveling platform for automatic tree‑pruning end‑effector
Dynamic performance test bench for smart agricultural machinery
