• display.left.bus [Default 1] left I2C display bus
• display.right.enable [Default True] enable right display
• display.right.address [Default 60] right I2C display address
• display.right.bus [Default 0] right I2C display bus
• rate [Default 5] (in Hz) display refresh rate
• motor.left.channel [Default 1] left motor channel on the I2C driver
• motor.left.wheel [Default sprocket_left_joint] left wheel joint name
• motor.right.channel [Default 4] right motor channel on the I2C driver
