PICO usefull info
- minimal angle = 2,35739
- maximal angle = -2,35739
- angle increment = 0,00436554
- scan.range.size() = 1081
Strategy
We will use one node that "spins" and subscribes to the sensordata, and publishes the velocities.
The main controller can be in five states:
- state_initialize: return initial setpoint??
- state_drive_parallel: Keep the robot at a fixed distance (setpoint) from the right wall while driving.
- state_gap_handling: When arriving at the center of a gap (to the right). Rotate in place untill parallel with new right wall.
- state_stop: Stops the robot when necessary.
- state_finalize: When no longer between two walls and no maze in front, abort.
Design approach & conventions
- datastructures.h: put all global variables and datastructures here.
- states: each contains the functionality of a state.
- conditions: each checks a certain condition to determine the next state.
- theseus is name of the package/node to execute
- theseus_controller is the controller that is iterated and runs:
Gather conditions e.g.: crash_avoidance, gap_detection. Based on the information a state will be chosen and executed. At the end of the state, the velocities will be published.
