Description of Proposed Mechanism:
Describe a mechanism that could solve your problem. You do not need to have this fully fleshed out with links and joints. Give us a general idea of what sort of mechanism you are looking at (i.e., the Geneva mechanism project).
The rod will attach to the end of a table, similar to when the rod rests on a boat
360 degree range of motion when casting the line - allows robot mechanism to move in order to mimic the movement of a bait or struggling fish, increasing the chance of catch
Spinning reel
“With all fixed-spool reels, the line is released in coils or loops from the leading edge of the non-rotating spool. To shorten or stop the outward cast of a lure or bait, the angler uses a finger or thumb placed in contact with the line and/or the leading edge of the spool to stop the flight of the lure. Because of the design's tendency to twist and untwist the line as it is cast and retrieved, most spinning reels operate best with fairly limp and flexible fishing lines.” - Wikipedia
Mechanical casting mechanism - utilizes a spring loaded or motorized system to cast the fishing line when activated by a controllerTo solve our problem, will we integrate three different mechanisms, all grounded to a fishing rod mount. The mount will attach to the end of a table or dock, similar to when a rod is resting on a boat. Our design will need to have two different functions, one to cast the line and one to reel it in. We will use two separate servo motors for each of these functions. The reel mechanism will resemble a four-bar linkage, with one junction grounded to the motor and one junction grounded to the reel handle. The casting mechanism will feature 2 functions, the forward-backwards whipping motion of the rod (planar motion), a 360 degree rotation of the rod to pick different areas of the water to cast. For the planar forwards/backwards whipping motion, we will use a gear train to achieve a variable speed of the forward/backwards motion coupled with a reciprocator to rotate the rod forwards and backwards. This will be detailed further in our preliminary design below. For the 360 degree rotation of the rod, we will use a slider crank connected to a servo.

Mechanism 4: Uniform Rotation to Variable Rotation - Casting
In order to ready the rod (move backward) and cast (whip forward) the input to the reciprocator will need to be
