+"""
+This example demonstrates how to control a tracked robot / RC car using this exact controller:
+https://www.aliexpress.us/item/3256806561829206.html
+
+The example just assumes a left motor and a right motor.
+The controls are simulated in this example with print statements.
+
+Note:
+For this exact controller, the right joystick doesn't map properly.
+I think it's a controller issue rather than an Inputs issue.
+up/down/left/right for the right joystick show as button presses.
+The left joystick works more like you'd expect.
