Modern pallet robots can typically stack goods at different heights, depending on their design, technical features, and application scenarios. Here are several key points that detail how pallet robots stack goods at different heights:
1. Multi axis movement ability
Pallet robots are typically equipped with multi axis motion systems (such as three-axis or six axis robotic arms) that can perform precise vertical and horizontal movements. These motion systems can coordinate in multiple directions, allowing robots to stack goods at different heights as needed. For example, the robotic arm of the robot can lift and lower vertically, adjust the position of the pallet, and operate flexibly in multi-layer shelves or stacking areas.

2. Vertical lifting function
Pallet robots generally have lifting platforms or adjustable height robotic arms that can be adjusted between different height levels. In this way, the robot can accurately stack the goods at the designated height according to the needs of accessing the goods. For example, in an automated warehouse, robots can stack goods on the upper level of elevated shelves without being restricted by the lower shelves.

3. Height perception and positioning system
Many pallet robots are equipped with height sensing systems (such as LiDAR, visual sensors, or ultrasonic sensors) that can monitor the position and stacking height of objects in real time. These systems enable robots to adjust their height according to the actual stacking situation, ensuring that goods are accurately placed in the predetermined position while avoiding collisions with other items.

4. Adapt to goods of different sizes
Different types of goods may require different stacking heights and stacking methods. Pallet robots typically have adjustable gripping methods and Pallet layouts, which enable them to adapt to the stacking needs of goods at different heights. For example, for taller or heavier items, robots can adjust the height and strength of their robotic arms, while for lighter or smaller items, they can choose a lower stacking height.

5. Multi layer stacking
Pallet robots can work in multi-layer shelves or vertical stacking areas, which can utilize the vertical space of the warehouse. For example, robots can stack goods layer by layer on pallets of different heights, making full use of limited ground space. This stacking method greatly improves the efficiency of warehouse space utilization.

6. Automatically adapt to access policies
Some pallet robots have automatic access strategies that can automatically select stacking heights based on the frequency of goods access. For example, fast-moving items can be stacked at a lower height for easy retrieval; Items with lower access frequency can be stacked on higher shelves. By dynamically adjusting the stacking height, robots can not only improve space utilization, but also optimize the efficiency of picking up and storing goods.

7. Dynamic adjustment and real-time optimization
Pallet robot systems are typically integrated with warehouse management systems (WMS) or warehouse control systems (WCS), and can adjust stacking heights based on real-time inventory status and order requirements. For example, when the inventory level is high, the robot will choose a higher location for stacking to avoid occupying the bottom space; When the storage space is tight, the robot will automatically adjust the stacking strategy to make the most of each layer of space.

8. Efficient stacking and unstacking functions
The pallet robot can not only stack goods, but also dismantle the stack and rearrange items according to the set rules. This enables robots to perform cargo distribution, sorting, and retrieval operations at different heights. For example, during order sorting, robots can accurately retrieve items from Pallets of different heights according to order requirements without the need for manual intervention.
