Robotic Crop Pollination Goal of New $1 Million Grant

Robotic Crop Pollination Goal of New $1 Million Grant

By Scott Weybright

Developing robotic technology for crop pollination is the goal of a new project for Washington State University scientists.

Funded by a nearly $1 million grant from the U.S. Department of Agriculture through the Washington State Department of Agriculture, the team is led by Manoj Karkee, an associate professor in WSU’s Department of Biological Systems Engineering and Center for Precision and Automated Agricultural Systems (CPAAS).

The three-year grant will also include scientists from Penn State University.

“Pollination is one of the important operations in orchards every year,” Karkee said. “Crops like apples, cherries, pears, and many more require pollination.”

Currently, crops are pollinated mainly by honey bee hives, which beekeepers move around to different orchards and crops. However, pollinator populations are decreasing and robotic pollination could be a more stable and efficient process.

The project will involve three steps:

  • Camera and machine learning systems. The research team must teach machines to detect and locate flower blossoms on trees in an orchard to target what needs to be pollinated.
  • Look at models for blossom development. Researchers need to determine when is the best stage to pollinate a given crop and a given location.
  • Develop a robotic hand and arm to spread pollen that will work with step one and will be tested in a lab and in the field.
  • Luckily, the team won’t be starting from scratch.


“We’ve been working for almost a decade on robotics in agriculture,” Karkee said. “For example, we have robotic systems that detect flowers for a robotic thinning system. We just need to adapt that to work for this project.”

The robotic pollinators also have hands and arms that can pick crops like apples, which they plan to adapt for pollinating blossoms.

The overall goal is to demonstrate capability for robotics to do this work, not build a full-scale machine, Karkee said.

“This is an important project, and a lot of work, but we’re confident we’ll be able to put together all of these different pieces into a viable prototype that could be a huge help for the agriculture industry in the future,” he said.

The project includes horticulturists from both WSU and Penn State, as well as engineering faculty from both universities. In addition to Karkee, the WSU team includes Changki Mo (Mechanical Engineering), Matt Whiting (Horticulture), and Qin Zhang (Biological Systems Engineering). The Penn State team includes Jim Schupp (Horticulture) and Long He (Biological Systems Engineering).

Why SaskSeed is Rejuvenating its Annual Meeting

Video: Why SaskSeed is Rejuvenating its Annual Meeting

The Saskatchewan Seed Growers Association (SaskSeed) is switching things up for 2024.

In a recent interview, SaskSeed President Kurt Printz, the owner of Printz Family Seeds, shared some of the notable accomplishments and changes within his organization over the past 12 months, including switching venues for the SaskSeed annual meeting coming up in January.

The decision to move their meeting from a familiar venue to a downtown location is a refreshing change aimed at offering members more freedom and a change of scenery outside of meeting hours, he says. The shift is also an attempt to attract a younger crowd, tapping into the vibrant dining and social opportunities downtown.

“The goal is to inject some fresh energy into the proceedings while still paying homage to the heritage of our meetings. It’s about blending excitement with respect for our established traditions, ensuring that the change doesn’t compromise the essence of what makes our AGMs special,” he says.

One of his proudest accomplishments as SaskSeed president is getting new executive director Chris Barker up and running within the organization. Printz expressed excitement about the positive direction Barker is taking SaskSeed and the impact this has on SaskSeed’s overall goals.
