Week 15 The final update.

We have made some changes to our designs.During the fabrication on last week , we found out that our mechanism is too small compared to the others.Lucky we still had enough material to make a bigger mechanism.The designs remained the same , only the size was increased.

This is the updated Auto Cad drawings for our mechanism.As you can see , the length and width are much longer.

The fabrication of the new mechanism has taken place.


Cutting and drilling took place during lesson time on the 27th July.


As you can see the new mechanism is now 1.5x bigger than the first.This is to ensure that the claw is able to grab the can.


This is the end product after cutting and drilling parts of the mechanism.



We attached the servo horn to the claws by use a screw and a nut.This ensures that the two parts are held in place.


On Wednesday the 28th , testing of the mechanism took place. One part of the mechanism was used to determined the direction and the speed of the mechanism.We programmed it so that the claw would not crush the can.

We had some trouble with the programming as we need to program two servo motors.The left and right parts of the claw was suppose to rotate in an opposite direction.But it happen to go in the same direction.After a few adjustments we managed to program it with the right speed and the right direction.
