pylabrobot.lib.liquid_handling.channel_positioning.required_spacing_between(channel_spacings: List[float], i: int, j: int) → float

Compute the required center-to-center distance between channels i and j.

Each channel’s spacing value is its diameter - the minimum distance its center must maintain from any neighbor. For adjacent channels, the required distance is the sum of both channels’ radii (half-spacings), ceiling-rounded to 0.1mm for safety. For non-adjacent channels, the distance is the sum of all intermediate adjacent-pair required spacings.

Parameters:

• channel_spacings (List[float]) – Per-channel spacing values (one per channel). Each value is the channel’s spacing diameter.

• i (int) – Index of the first channel.

• j (int) – Index of the second channel.

Returns:

Required center-to-center distance in mm, ceiling-rounded to 0.1mm.

Return type:

float
