Not all pallet robots necessarily have multi axis robotic arms. Whether or not to be equipped with multi axis robotic arms depends on their structural design, application scenarios, and functional requirements. Below are some explanations:

1. Multi axis robotic arms are commonly used in "robot type tray systems"
■Multi axis robotic arms (such as 4-axis and 6-axis) are commonly used in articulated pallet robots and have high flexibility.
■This type of robot can perform complex actions such as grasping, rotating, tilting, etc., and is suitable for:
■Multi angle stacking
■Handling of Alien Items
■Mixed palletizing or flexible unpacking scenarios.

2. Some tray robots use fixed tracks or linear structures
■Some tray robots adopt gantry, linear, or shuttle structures, moving along fixed trajectories with only 2-3 degrees of freedom.
■This type of system is more suitable for efficient repetitive stacking of standard boxes and uniformly shaped goods, without the flexibility of multi axis robotic arms.

3. Whether it has a multi axis robotic arm depends on the application requirements
■If the warehouse requires flexible stacking, diverse items, and frequent directional changes, multi axis robotic arms are the ideal choice;
■If only handling standard cardboard boxes and regular pallet stacking, using simplified structures such as slide rail robots or lifting platforms can meet the needs and have lower costs.

4. Multi axis robotic arm lifting operation degree of freedom
■Multi axis robotic arms can move freely in X/Y/Z directions and multiple angles, suitable for:
■Irregular stacking of goods
■Multi angle grasping
■Complex tasks such as precise alignment and placement.
■Especially suitable for automated production lines or mixed tray applications with small space but high operational requirements.

5. Non multi axis structure facilitates large-scale deployment and maintenance
■Tray robots without robotic arms have simpler structures, lower costs, and are easier to deploy on a large scale;
■Maintenance is also easier and suitable for standardized operation warehouses.

6. Multiple robot structures can be used in combination
■In an automated warehouse system, pallet robots with and without robotic arms can be deployed simultaneously:
■Responsible for irregular and complex processes with a robotic arm;
■The non robotic arm pallet truck is responsible for high-speed handling, loading and unloading of pallets, and loading and unloading areas.
