You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: cherrypick_handler.rb
    path of file: ./repos/sequencescape/app/models/tasks
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

# Handles the behaviour of {CherrypickTask} and included in {WorkflowsController}
# {include:CherrypickTask}
module Tasks::CherrypickHandler # ruboco
    
  def setup_input_params_for_pass_through # rubocop:todo Metrics/AbcSize
    @robot_id = params[:robot_id]
    @robot = Robot.find(@robot_id)
    @plate_type = params[:plate_type]
    if params[:nano_grams_per_micro_litre]
      @nano_grams_per_micro_litre_volume_required = params[:nano_grams_per_micro_litre][:volume_required]
      @nano_grams_per_micro_litre_concentration_required = params[:nano_grams_per_micro_litre][:concentration_required]
      @nano_grams_per_micro_litre_robot_minimum_picking_volume =
        params[:nano_grams_per_micro_litre][:robot_minimum_picking_volume]
    end
