2.1.2 Shagai Gripper
Figure 2: Gripper for the Shagai
In reference to Figure 2, this design is based on the shape of the Shagai because it
gives more friction to grip and transfer it to the throwing area of the base. Pneumatic is also
used in this design to open and close the gripper. The dimension is 70 cm (L) x 30 cm (W)
x 25 cm (H) while the mass is 700 g.
2.1.3 Shagai Throwing
Figure 3: Mechanism for catapult
The throwing mechanism originates (see Figure 3) from the concept of catapult
where pneumatic is used to pull the shaft of the catapult to create enough force to throw the
Shagai with a specific angle. With the right angle, this will ensure a proper landing for the
Shagai. The dimension is 62 cm (L) x 45 cm (H) x 16 cm (W) with a mass of 1100 g.
