Finishing the hydraulic arm - Plan for the day and reflection

Plan for the day:

Today we need to attach both of the upper and lower arms syringes. We need to make sure we attach them securely so they don't shift around. We need to finish our presentation slideshow and finish our presentation board.

Reflection:

Today we attached the upper arm

syringeand the lower arm syringe.

They didn’t work because we realized

that the arm is too heavy for the 10ml

syringes to lift so we would of had to use

20ml syringes so it has the power to lift it up.

Last night James and Danielle cut and glued photos on the science board. If we were to do this project again we would use 20ml syringes so it would actually be able to move.

Attaching all the syringes to the arm

Plan for the Day:

Today we are going to attach the claw syringe to the arm. We also need to attach the upper arm, lower arm, and turning syringe to the arm and if we don’t finish this today we will need to do it at home. We need to make sure that the syringes are secured tightly so that they arm will function smoothly and not move around. We will need to make sure that each individual syringe is functioning perfectly before we move onto the next syringe. We will also need to find what is the best way to attach the syringes to make sure they are sturdy and don’t move.

Reflection:

Today we got a science board
and started planning what we
are going to put on it.



We also started a presentation slideshow and put things like what we have learnt, why we chose this project and impact on the community.


We found out that the metal
we used for the claw was too
strong so we had to use slightly
weaker metal.

We started attaching syringes
to the arm. We glued and attached
the claw syringe on and it works and
we finished the  turning syringe.We have
decided not to do a control panel because
it was one of the reasons the prototype did not work.

Filling the syringes 7/09/2018

Plan for the day:
Today we need to put the spacer under the two claw pieces. We then need to start attaching the syringes to the syringe pipe and watch the video to accurately fill the syringes. We need to figure out exactly where we need to put the syringes on the arm and start attaching them. We also will need to find good quality wire for the two claw pieces.

Reflection:

Today we cut out the spacers, drilled a hole through them and attached the under the two claw pieces.

We filled the syringes with the food dye and water making sure we did it is exactly like the video. We made sure you could see the colour and it popped.

We bent some strong wire into a Z shape to pull the claw. We also drilled holes into the syringe and claw so now the claw is working we just need to attach it.

We also started a document with what we talked about with Wian Van der Worm and his opinion and ideas. It helped us learn more about hydraulics. He also printed some paper for us that had lots of hydraulics information on it. It was quite complicated for us but we got the basics. Next week we need to finish adding all the syringes and finish the presentation.
