# `BB.Dsl.Transmission`
[🔗](https://github.com/beam-bots/bb/blob/main/lib/bb/dsl/transmission.ex#L5)

Mechanical transmission between a joint and its actuator(s).

Captures the relationship between joint-space command and motor-space
command — gear reduction, zero-offset, and polarity. The URDF equivalent
is `<transmission>`.

# `t`

```elixir
@type t() :: %BB.Dsl.Transmission{
  __identifier__: any(),
  __spark_metadata__: Spark.Dsl.Entity.spark_meta(),
  offset: nil | Localize.Unit.t(),
  reduction: number(),
  reversed?: boolean()
}
```
