Reward: The agent is rewarded for moving to the right, keeping it's head above it's legs, and not bending it's limbs too much
Actions: The agent can power motors that rotate each limb within a certain range of motion
State: The agent can "see" most things about itself: each limb's relative position, global position,
rotation, linear velocity, angular velocity, and orientation. Also each joints angle, speed, and motor
