feat(big_bear): add BigBear orbital shaker driver#1174
Merged
Conversation
A daisy-chained orbital shaker: one serial line addresses up to 16 shaker
positions ("nests"), each by a 1-based hex id. Adds a single-class driver
(BigBearOrbitalShaker) over pylabrobot.io.serial with start/stop shaking,
homing, and serial-number readout.
Serial: 9600 8N1, no handshake, carriage-return terminated. Commands are
"@<id><cmd>"; value sets are followed by a "@<id>?<c>" read-back and an
"@<id>Q" status poll. A rejected command replies "?:".
Not verified against hardware; setup() emits a warning to that effect.

Add a hello-world notebook covering daisy chaining, setup, per-nest and whole-chain start/stop, homing, and serial-number readout, plus the user-guide index entry. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Replace the OrbitalShakerSequence enum with a Literal["CW", "CCW"] argument, validated at the call site. Also fix an invalid cell in the user-guide notebook (missing required code-cell fields). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Adds a driver for the BigBear orbital shaker, a daisy-chained orbital
shaker where a single serial line drives up to 16 independently-addressed
shaker positions ("nests").

so they can be tuned during bring-up.
