WEEK 4

PART 3 : FINAL (SOON) PROGRESSION OF THE HARDWARE PART

For this week I decided to make some testing on the actuator motor and the stability of the seat to hold the weight of a person. 

The video shows that how the actuator motor will work. The actuator move upward when the power supply is on. The power supply for this actuator motor is 12V dc and I have tested it with a power adaptor that I borrowed from my supervisor . Thank you sir 😊 

The video shows how the seat move downward. This is only the testing of the functionality of the motor to work. 

Next would be the stability of the seat . Here a video of the actuator motor actually move with a person sit on the wheelchair.

In this video, the person weight about 40 kg to 50 kg. So it is prove that the actuator motor can hold a person with that range of weight. The actuator motor still use the same power supply to move. while the stability of the seat is still under progress and it will be secured after all the modification have been finalised. Here is the video of the actuator motor move downward while the a person sit on the wheelchair.

Some of the picture that prove the actuator motor can hold a person weight.

It is safe for a person to seat on the wheelchair as it is proven

while for some extra safety of a person on the wheelchair, an extra back support is added up at the back of the seat .

Also, a foot rest had been installed to the wheelchair for the person's comfort.

So that's all for this week progress. The next task that my supervisor gave me are:

b) To add up some information in the report journal
