What types or crop packaging robot exist?

Crop packaging robots are quite varied in their designs and functionalities. This diversity is key for addressing the unique needs of different agricultural tasks. The different types of crop packaging robots can broadly be categorized based on their operation method, task specificity, and mechanical construction. Here are some prominent types:

Six-axis robots

Six-axis robots have emerged as a transformative tool in the agricultural sector, specifically in the arena of crop picking. These robots, characterized by their six degrees of freedom, can replicate the complex movements of a human arm. This makes them highly adept at navigating intricate environments. 

For instance, in a fruit orchard, a six-axis robot can extend, rotate, and maneuver its arm to pick fruits that might be nestled amid dense foliage. These robots do so without causing damage to the tree or the fruit. The robot's high degree of precision and gentle handling helps maintain the quality of the produce, reducing crop loss due to bruising or dropping.

Collaborative robots (cobots)

These robots look very similar to six-axis robots. However, a key differentiator for cobots is that they are designed to work alongside humans in shared workspaces. Cobots can assist people in tasks like packaging and palletizing. They are built to be safer than industrial robots, flexible, and easy to program. 

Custom-built robots

Some applications may require highly specific functionality that isn't covered by standard robot designs. In these cases, custom robots are built to cater to specific needs. For example, the handling of young nursery plants requires special tools and specific capabilities that standard robot types aren’t optimized for. Using specialized technology enables farmers to maximize the performance of their automation systems for a particular task.

Each of these types serves different purposes and can significantly enhance crop packaging operations' efficiency, accuracy, and productivity. The choice of robot type depends on the specific needs of the agricultural process in question. Common factors to consider when selecting a robot include:

  • Type of crop
  • Scale of operations
  • Level of precision required
  • Reach requirements
  • Payload requirements
