Radio

You can create a radio component with radio:

ui:
  components:
    - key: voltage
      type: radio
      label: "Power Supply Voltage"
      description: "Select the test voltage"
      required: true
      options: 
        - label: "3.3V"
          value: "3.3"
        - label: "5.0V"
          value: "5.0"

Properties

Display

You can configure how the radio component appears to the operator.

Property	Type	Required	Description
`key`	`string`	Yes	Unique identifier for accessing the value
`type`	`string`	Yes	Must be `"radio"`
`label`	`string`	No	Display label for the radio component
`description`	`string`	No	Helper text displayed below the radio component

Value

You can set default values and bind to measurements or unit properties.

Property	Type	Required	Description
`default_value`	`string`	No	Default selected option value
`bind`	`string`	No	Bind to unit property or measurement. See Collect Input for details.

Options

You can define the list of mutually exclusive choices.

Property	Type	Required	Description
`options`	`array`	Yes	Array of objects with `label` and `value` properties

Each option object has:

Property	Type	Description
`label`	`string`	Text displayed to the operator
`value`	`string`	Value submitted when selected

Validation

You can validate selection before the value is submitted.

Property	Type	Required	Description
`required`	`boolean`	No	If true, operator must select an option (shows "Required" badge)

TofuPilot validates operator input before submission, preventing continuation until all constraints are met. For some workflows, this input validation can create workarounds where operators bypass the UI to proceed.

Instead, you can capture the input as a Measurement using Binding and validate it with Validators. TofuPilot will record the actual operator input while enforcing pass/fail criteria.

Examples

Test Mode Selection

We'll let the operator choose between different test modes:

phases:
  - name: Configure Test
    ui:
      components:
        - key: test_mode
          type: radio
          label: "Test Mode"
          required: true
          options: 
            - label: "Quick Test (30s)"
              value: "quick"
            - label: "Standard Test (2min)"
              value: "standard"
            - label: "Thorough Test (5min)"
              value: "thorough"

Quality Level

We'll collect quality assessment from the operator:

phases:
  - name: Quality Assessment
    ui:
      components:
        - key: quality_level
          type: radio
          label: "Quality Level"
          description: "Assess the overall quality"
          required: true
          options: 
            - label: "Excellent"
              value: "excellent"
            - label: "Good"
              value: "good"
            - label: "Acceptable"
              value: "acceptable"
            - label: "Poor"
              value: "poor"
