A compact, high-speed AMR purpose-built for individual carton and parcel handling — autonomously sorts, buffers, and transfers cartons at 1,000+ units/h without fixed conveyor infrastructure.
A หน่วยโอนกล่อง (CTU) is a compact, high-speed AMR designed specifically for individual carton and parcel handling. Unlike a tote-carrying CMR, the CTU's onboard conveyor is optimised for single-carton, high-cycle operation — picking up one carton from an infeed station and delivering it to any of hundreds of chutes, packing lanes, or despatch conveyors in the facility.
The key differentiator is throughput: a CTU fleet achieves 1,000+ carton sorts per hour across any-to-any routing, without the fixed cost or layout constraints of a traditional crossbelt or sliding-shoe sorter. The system scales linearly — double the robot count, double the throughput, with no mechanical or infrastructure changes.
CTUs are particularly effective in order fulfilment operations where each customer order requires a different carton destination, and sortation routing changes frequently (daily or hourly) based on carrier cutoffs, peak promotions, or carrier allocation changes.
At 15 m average route length, a 20-CTU fleet processes 1,000+ cartons/h. Throughput scales linearly — add robots for more capacity, no mechanical changes.
Any chute, packing lane, or conveyor port on the map is a valid destination. Sortation rules in WMS change instantly — no hardware reconfiguration needed.
Multi-face barcode scanner at the induction station reads 1D/2D codes on any carton face with >99.5% read rate — no manual scan required for induction.
CTU fault → FMS re-assigns task to another CTU in <30 s. The system never stops for a single robot failure — unlike a fixed sorter where one belt fault stops the line.
Handles cartons from 150×100×50 mm up to 600×400×400 mm and up to 30 kg — a single CTU type covers parcels, shippers, and polybag-on-board configurations.
WMS sortation rules connect directly to carrier cut-off windows, route coding, and OMS wave plans — cartons are automatically sorted to the correct carrier chute and close-time sequence.

Carrier sortation, batch-to-single order collation, and peak-volume despatch management with dynamic chute assignment.
Postcode/route sortation for last-mile carrier operations — replace fixed crossbelt sorter with a CTU fleet that reconfigures sortation rules in seconds.
Sort cartons to store, department, or delivery route lanes — supports multi-store despatch and cross-docking operations from a single CTU fleet.
Sort individual part cartons to assembly line kitting stations — JIT delivery of the right carton to the right station without manual trolley pushing.
Tote-level conveyor bridging for heavier unit loads — the CMR pairs with the CTU in multi-tier sortation systems.
Goods-to-person picking upstream of the CTU — LMR delivers pods, operators pick to carton, CTU sorts cartons to despatch.
High-density tote ASRS — buffer cartons before CTU sortation in a shuttle system for peak-smoothing in despatch windows.
