 This project aims to train the COEX Clover quadcopter equipped with an array of
 Time of Flight (ToF) sensors to perform basic navigation and obstacle avoidance
 in randomized scenarios using a Deep Deterministic Policy Gradient (DDPG)
-reinforcement learning algorithm. Using randomized environments will test the
+reinforcement learning algorithm. Using randomized environments tests the
 effectiveness of curriculum learning for reinforcement learning and the overall
 strengths and weaknesses of DDPG for quadcopter control.  By training the
-quadcopter to explore randomized environments, this can also demonstrate how
-using simpler, more economically affordable sensors can enable a quadcopter to
-fly in a GPS-denied environment without the use of LiDAR, which is typically an
-order of magnitude more expensive.
