A Kino widget for controlling robot joint positions.

Displays a table of all movable joints with:

• Joint name and type
• Current position (updated in real-time)
• Position limits (min/max)
• Draggable slider for setting target position

Safety: Controls are only enabled when the robot is armed. Moving a slider waits for the actuator to accept the command and shows the refusal if it doesn't, so a joint that isn't moving says why.

Usage

BB.Kino.JointControl.new(MyRobot)

The widget automatically:

• Discovers all joints from the robot topology
• Subscribes to sensor messages for position updates
• Subscribes to state machine for armed/disarmed state
• Sends position commands to actuators when slider changes
