Week (12), (13)
Description
This session has lasted a little over 2 weeks as I have been busy with Christmas coming up but I have managed to find time to get some work done on this project and dissertation.
Equipment:
3 x Long black metal U brackets (left over from robotic arm kit)
1 x Square Mechano Block
1 x Servo (Mg996r)
1 x L bracket
1 x tilt bracket
1 x Circular Arm Horn
2 x 2mm Brass rods
Milliput
4 x Brass Blocks
This session was spent putting together the neck framework for the Animatronic and attaching the eye mechanism together. I decided to use the U brackets left over from the robotic arm kit and attach them together to make a rectangular shape, I fixed them in place using the pre drilled holes and nuts and bolts. The top of the rectangular frame then fit onto the top tilt bracket of the upper jam mechanism I secured this in place using nuts and bolts and Milliput. I then took a Servo and added a pan and tilt bracket to it with the circular arm horn attached the to servo drive connector, i then attached the L bracket to the middle of the U bracket and attached it to the middle of the rectangular framework. To attach this new framework to the base I had to screw a Tilt bracket on the central platform of the base mechanism, this was simple as it has the pre drilled holed to do so. Attching the new neck framework was difficult though as I had run out of L brackets so I had to improvise using a Square Mechano block which luckily matched the holes in both the tilt bracket attached to the bottom of the base mechanism and the tilt bracket attached to the neck framework. 1.1, (Note the eye mechanism is not attached to the top jaw mechanism and the base unit is not operational, i have just placed these elements together to get a feel for how the build will look when the parts are attached together)
Eyes:
To attach the upper and lower eyes mechanisms together i attached a brass block to the end of each rod. I then took the 2mm brass rods and slotted them into the end hole of the brass block connectors.
to keep these in place i used milliput to bond the two sections of each frame together. In addition i also added milliput to the brass blocks on the front eye mechanisms because the screws where coming loose and I had to constantly tighten them hopefully the milliput will stop the screws from turning.

When we where coming back from visiting my parents on Thursday Caroline took this shot of our house in the rain and it struck a Chord with me regarding the Aesthetics of the build. The picture feels cold and industrial and the light emanating into the night gives and unnatural aura against the night sky reflecting the rain drops. 1.4
Feelings
My feelings of this extended session are positive I think that the build is starting to come together and I am pleased with the way all the old and new elements have come together.
Evaluation
This was a good experience considering that some of the parts did not fit together as I had envisaged and I had to find ways of getting them to work together. This is an area of the build I am enjoying the most problem solving and think of ways around issues. I makes the project feel less like its parts cobbled together and more like they have some purpose.
Analysis
The current situation of the build makes sense although the new elements fit together well there may be future issues regarding the stability of the neck framework and how it is attached to the base. I will not be able to fully explore and analyse this situation until I have finished and connected the eye mechanism to the top of the jaw bracket. However for the purpose of the build in its current state this issues causes no problems concerning the testing of the elements.
Conclusion
In conclusion I feel a fair amount of work has been achieved considering the time of the year and other on going projects. I don't feel that anything else could have been done to improve the work done in this session.
Action Plan
If I had to re-do this session I don't think I would have changed much considering what has been achieved however I do feel that further on down the line I will have to alter or strengthen some parts of the framework to make it more sturdy.
