Mixed Carton Environments: The Real Test of Automation
In real warehouse operations, carton unloading rarely involves standardized conditions. Instead, operators face:
- Mixed carton sizes and weights
- Irregular stacking and uneven layers
- Tilted or compressed boxes
- Non-standard pallet arrangements
These mixed conditions have long prevented large-scale adoption of automated unloading systems. Most traditional solutions rely heavily on standardized carton dimensions and structured stacking. Once deployed into real mixed-carton environments, performance stability drops, efficiency decreases, and collision or product damage risks increase significantly.
Messol-S was designed from the outset to address this industry bottleneck.
It treats mixed cartons as the baseline operating condition — not an exception. The system demonstrates adaptive recognition of non-standard stacking patterns and continuous autonomous operation across diverse carton specifications, enabling true “no limitation on carton type or stacking method” automation even under highly complex working environments.
From Perception to Execution
Four Core Capabilities of Messol-S
Powered by ENGOAL’s embodied intelligence large-model vision algorithm, Messol-S enables a fully autonomous closed-loop process covering recognition, grasping, obstacle avoidance, and transfer.
1. Accurate Perception
AI-Enabled Dual 3D Vision for Full-Scene Understanding
Messol-S integrates a dual 3D vision system supported by AI perception algorithms. Stereo cameras perform full-environment scanning, capturing RGB images and depth data in real time to generate 3D point cloud models.
In mixed-carton scenarios, the embodied intelligence system automatically:
- Identifies each carton’s position and orientation
- Determines optimal graspable surfaces
- Adapts suction layout dynamically
- Chooses between single or multi-carton picking
Motion commands are precisely issued to the robotic arm, and a visualization interface displays the planning results in real time for full operational transparency.
2. High Throughput Picking
Dual-Mode Adaptive Switching for Flexible Execution
Messol-S intelligently switches between two picking modes depending on risk level and stacking conditions:
Single-Shot Mode (One Scan, One Pick)
For high-risk or unstable stacking scenarios, the system re-scans before every pick. This ensures precise positioning and stable placement onto the conveyor, minimizing the risk of carton shifting, tilting, or dropping.
Multi-Pick Mode (One Scan, Multiple Picks)
For lower-risk and standardized cartons, the AI performs a single global scan, autonomously plans optimal picking sequences, and executes multiple consecutive picks without interruption. This significantly increases unloading rhythm and reduces batch handling time.
3. Intelligent Obstacle Avoidance
Multimodal AI Perception for Collision-Free Planning
Mixed stacking environments introduce elevated collision risks due to uneven heights and unpredictable spacing.
Messol-S integrates multimodal perception — combining image, depth, and point cloud data — to monitor motion trajectories in both horizontal and vertical dimensions.
The AI system autonomously:
- Determines front-facing or side-grasp strategies
- Identifies obstacles in real time
- Adjusts motion paths dynamically
Every pick-and-place cycle is executed with safety-controlled precision, reducing downtime and preventing cargo damage.
4. Operational Stability & Monitoring
Closed-Loop Intelligent Safety Control
An intelligent lifting conveyor dynamically adjusts height based on picking position and synchronizes with robotic motion under unified AI scheduling.
From suction contact to conveyor transfer, the entire process remains coordinated and seamless.
The system provides:
- Real-time operation tracking
- Event recording and traceability
- Immediate alerts for anomalies such as conveyor blockage or dropped cartons
- Full process data logging for diagnostics
This ensures stable, traceable, and safety-controlled operation throughout the unloading workflow.
From Heavy-Duty to Flexible Scenarios
A Comprehensive Product Portfolio for Industrial Dock Automation
ENGOAL has built a full-spectrum automated loading and unloading portfolio tailored to different industrial scenarios:
