# Example file instantiating the Videre robot driver # All options you might want to use are instantiated here # In general, the player standard units are # translational velocity: m/s # rotational velocity: deg/s driver ( # Standard player options for presenting this instance of the driver name "erratic" # Standard player option, tells the driver to expose all interfaces, and # assigns them IDs provides [ "position2d:0" "power:0" "aio:0" "ir:0" "sonar:0" "ptz:0" "tilt:::ptz:1" ] # Serial port to use for connecting to robot # USB/serial link would be /dev/ttyUSB0 port "/dev/erratic" # Maximum translational and rotational speeds accepted during operation. # This is also capped by robot's internal hard limits, potentially lower than # given here. For Erratic, it's about 2 m/s and 720 deg/s max_trans_vel 0.5 max_rot_vel 200 # The robot uses these acceleration values to achieve desired velocity. There # is a hard minimum acceleration as well as a top one, set by the robot. trans_acc 0.5 rot_acc 100 # If set, these specify the robot to use another acceleration when target # velocity is zero. # trans_decel 0.5 # rot_decel 100 # Parameters for the PD control loop onboard the robot. When in individual # wheel control, translation parameters are used for each wheel control. # Warning: Changes can have unexpected effects, including truly erratic # behavior. pid_trans_p 40 pid_trans_v 100 pid_rot_p 40 pid_rot_v 100 # These set how to drive the wheel motors. Frequency affects noise, and # perhaps power efficiency. motor_pwm_frequency 16000 motor_pwm_max_on 0.7 # Set to 1 to have the driver use individual wheel control. PD settings for # translation will be used. This might be useful depending on the kind of # control loop in your application, but probably you want to leave it at 0 # (default). direct_wheel_vel_control 0 # Setting this option to 1 saves the settings in the robot, making permanent # whatever settings state it is in after settings of this config file are # applied. The settings can then be left out of other configuration files. # Note that some of the settings here are driver settings and not robot ones, # and are therefore not affected by a save. # NOTE: If a bad setting messes up the behavior of the robot, it can be reset # to factory defaults by holding down its button while powering it up. save_settings_in_robot 0 )
