Execution Engine Robot Status Display

The robot control and display area shows the current state of the robot itself, including information regarding sensors, motors, navigation, etc. It includes physical and calculated inputs (sensors and current direction) for use in rule selection and actuator and calculation outputs (motors and navigation command) from a selected rule.

Sensors, Direction, Navigation, Motors and Robot State

As each rule is executed, the status of the sensors, direction, navigation, motors and robot state are displayed. Detailed information regarding the meaning of each element is available in Rule Editor Help where rules are developed and these elements are defined.

Execution Control

The execution control panel provides several buttons that allow the robot to perform it's activity:

Go - full steam ahead!
Step - step slowly through execution
Stop - STOP!
Redo - start over from the begining
Back - will go back to the prior 100 rules
Frwd - move forward from this rule
note: Back, Forward and step buttons are helpful debugging facilities

Link Status

The status panel displays the current status of the robot link (whether it's up or down).

Run Mode

This pull-down menu allows the user to select Real, Virtual or Unspecified. The default value is unspecified, indicating the user has not selected a run mode. The 'GO' button in Execution Control will not be made available until the user selects a run mode. In real mode, the actual lego car negotiates real lego tiles. In virtual mode, a virtual map is built and a virtual car negotiates the map. Additional information regarding the Virtual Substrate is available in Virtual Substrate Help where a map can be built and execution of the virtual car can be observed.
