 **Project Statement**: "To create a modular platform for research in controls and embedded systems."
 
+Since 1998, MicroCART has been building aerial robots. Currently, we are
+building a quadcopter that can fly autonomously.
+
+MicroCART has 3 areas of development:
+- The quadcopter itself
+  - The quadcopter has been built from the ground up, incorporating a
+    Zybo board that provides the processor and a FPGA, an IMU sensor, motors,
+    props, a LiPo battery, a receiver for manual remote control, and a frame 
+    that holds it all together.
+- The ground station
+  - The ground station is responsible for issuing important data to the quad
+    (like position data from the camera system), and issues commands to the quad
+    for things like configuration and path following directives.
+- The Controls Model
+  - The quadcopter processor is programmed to implement a PID controller. We use
+    a Simulink model to streamline the PID tuning process and to facilitate
+    effective characterization of the quad.
