Ultrasonic Depth Sensor Emulation

[frawgii]

Just like what the rover has, we want to emulate the ultrasonic depth sensor in the simulator.

• We want to add an ultrasonic sensor to the rover on the simulator.
• This will allow us to know the distance of objects regardless of features such as texture or color.
• The current depth/distance from an object the rover is via the sensor will be displayed.
