Tip selection based on volume - Venus Hamilton

[EricSindelar_Hamilton]

There are some threads and examples on the forum. There are multiple approaches one can take using VENUS. In my opinion, the most straightforward would be to separate transfer volumes into an array for 50uL tip transfers and an array of 300uL tip transfers. The examples posted in the thread below demonstrate one way of accomplishing this:

Method Writing Exercises

You may want to check out this zip file that contains some VENUS challenges on arrays and barcoding. It includes a word document that reads like a set of basic user requirements and with each exercise, it adds more feature requests so you can iteratively build a more complex method. See below for an excerpt of Exercise 1: [image] The zip file contains completed examples of each exercise so you can compare. Part of the point of the exercise is to also anticipate what may be needed to make a m…

For something more advanced, you can refer to this thread. This thread provides some examples of how you can pick up different tip types and transfer the volumes together:

Tip Handling for Widely Varying Volumes

Wondering if anyone has a good solution for this problem: I’m trying to create a universal, one-size-fits-all solution to cherry picking using incoming worklists for plate mapping and transfer volumes. The issue that keeps coming up is the huge range of transfer volume that we can expect (anywhere from 1 uL to ~800 uL, essentially the full range of a STAR channel pipette). The difficulty is programming the robot to pick up appropriately sized tips for each transfer; what I’ve done so far is: s…
