 There are two path planning generators called   ```Linear Path Generator``` and ```Spiral Path Generator``` to generate the motion of the turtlebot in the simulated obstacle free environment. The ```Linear Path Generator``` generates a linear path for the turtlebot in the collision free area. Whereas, the later generates discrete spiral path. ```CollisionDetecter``` overrides ```Linear Path Generator``` and ```Spiral Path Generator``` whenever an object is in the vicinity of the turtlebot.
 
 
-The ```CollisionDetecter``` algorithm divides the vicinity of the turtelbot into two areas : ```Front``` & ```Rear```. It then compares the obstacles in these two vicinities and make a decision either to move forward or to rotate. <TODDO: elaborate the algorithm>
+The ```CollisionDetecter``` algorithm divides the vicinity of the turtelbot into two areas : ```Front``` & ```Rear```. It then compares the obstacles in these two vicinities and make a decision either to move forward or to rotate. 
 
 The ```Linear Path Generator``` or ```Spiral Path Generator``` kicks in back once both of the vicinities are obstacle free.
