TASK TERMINATOR
A 4-wheel platform equips abilities to complete multiple tasks
Mission
Task Terminator is a robot made for fulfilling all the challenges in the Taiwan TDK Robocon. The competition includes three main challenges: grab a marker and write alphabets, another one is to imitate human arms' actions like pull a door ring and reach in a curve tunnel, and the other is to catch a volleyball shoot into a basket.
My role | Team Leader and Arm Design
I led a team with classmates participating in the 19th TDK Robocon. Prior to finalizing the design, I conducted a brainstorming meeting and listed out our ideas, then illustrated the first CAD. Prepared for ten months, our team constructed a solid 4-wheel drive base within one week. I composed and examined two different mechanical designs of robotic arms, one for gripping a marker writing words on a vertical whiteboard and the other one for tabbing a volleyball through a curve tunnel imitating a human's gesture of arms. Besides, I also layouted a PCB board using H-bridge circuits with eight relays controlling the mobile base.
Development Process
Phase 0 - Brainstorm
In the brainstorming meeting, we listed out our ideas and narrowed them down to a few options we wanted to exam.
Phase 1 - CAD
3D CAD design for examining any potential collision from different parts of mechanisms.
Phase 2 - Prototype
Construct prototype used for testing functions, easily being implemented different mechanism and changing design.
Phase 3 - Finalize
The final version of the robot after finalizing the design.
Robot Task
Task Terminator is the product made for TDK Robocon where robots compete to complete a series of tasks within a set period of time.

Task 3
Starting Point
Double-check all items, such as air pressure in the tank and better voltage, on the SOP check-list before starting.
Task 1
Grab a marker using two DC motors to roll in and hold it.
Task 2
Write worlds on a vertical whiteboard.
Task 3
Put the marker right into the specific bin.
Task 4
Tab a volleyball through a curve tunnel to imitate human arms' gesture.
Task 5
Catch the volleyball rolling from the curve tunnel and carry the ball.
Task 6
Hold the ball safely while passing several obstacles.
Task 7
Aim to the basket and shoot the ball. Take the other 3 balls put beside and shoot again.
