Robotic seed-handling apparatus and methods

The present invention relates to robotic apparatus and methods for automatically transferring small articles, such as seeds, between donor and recipient locations (e.g., respective containers) and optionally, for weighing the transferred articles. Robotic apparatus for transferring and distributing small particles, such as seeds, contained in covered or uncovered containers, such as capped jars, are disclosed. An exemplary apparatus includes a vacuum-activated probe configured to pick up a selected number of seeds from a donor container and to deposit the seeds in a selected recipient container. The seeds being transferred may be weighed during the transfer process by depositing the seeds in a crucible of a microgram balance or analogous device. After weighing, the seeds are picked up using a second probe that transfers the seeds to a recipient container. Also disclosed are automated methods for transferring and weighing particles, such as seeds.
