+# The mindstorms_widgets class is a wrapper for the python-ev3dev
+# language binding. It implements interfaces that correspond directly
+# to the action and sensor programming blocks (widgets) from the
+# mindstorms LabVIEW software. This allows leverage from the amazing
+# documentation already provided by Lego. Some exceptions are:
+# * It doesn't auto-detect the devices. You need to call
+# connect_motor or connect_sensor first for each device you use
+# * Only two large motors and one medium motor are supported.
+# This simplifies the interfaces. The motors are referenced by
+# the following names in the interfaces:
+# 'medium' motor, default Port A
+# 'right' large motor, default Port B
+# 'left' large motor, default Port C
+# * degrees and rotations inputs must always be positive
+# use negative power to go backward
+# * Rather than having a separate unregulated_motor widget, regulated is an
+# an optional input parameter (default = True)
+# * motor_rotation_measure, 'current_power' returns both the duty_cycle_sp
+# (the actual power level being applied to the motor) and speed_sp
+# * sound includes an option to give a sentence and have the robot speak
+
+# Known issues/limitations
+# * The degrees, rotations, speed and invert values provided as inputs do
+# not map directly to the values programmed to the sysfs attributes i.e.
+# if you don't use mindstorm_widgets methods exclusively to control the
+# motors you will need to explicitly initialize all the relevant sysfs
+# attributes each time you program the motor from outside mindstorms_widgets
+# * led_flash
+# * no error handling/recovery
+# * volume for tones doesn't work very well (seems to have only 2 levels)
+# * when reading the heading and proximity in beacon mode, ir_sensor_measure
+# returns good values at first but continuing to poll it seems to result
+# in inconsistent values
+# * ultrasonic and gyro sensors are not implemented
+
+# Mindstorms uses the following coefficients to compute speed_sp
+# based on a power input in range 0-100 i.e. speed_sp = x * power
+# medium motor: x = 16.4
+# large motor : x = 10.3
