Project 7. Pneumatic Lego
In the pneumatic Lego practice,
each team will receive a box of pneumatic Lego package, which contains one air
pump, two double acting cylinders, two 5/3 valves, in addition to the many
tubes, connectors, and building blocks. Please check if you have these
important pneumatic components in the package. Report to TA right away if you
find some of the important pneumatic components missing.
There are many example cards.
Pick one as the topic of your pneumatic Lego practice. Assemble the Legos
according to the example card, make sure it works, and draw the pneumatic
system schematic diagram.
Ask the TA to check your Lego
project and diagram. Disassemble the Legos and return the package to the TA.
Ask the TA to check if all the important pneumatic components are there. Each
student who attends this practice gets 2 bonus points.
During the process, please
record the details, make drawings, take photos etc., to prepare for the report
of your Project 7.
Project 7 is a complete design
report for the pneumatic Lego practice. Here are my suggestions of the content,
but you can certainly have your own thinking:
A description of the product you are building, especially the
functions to be achieved by pneumatic system.
A step-by-step description to the mechanism of your design, an
engineering drawing will certainly help. Note that the double acting cylinder
is the actuator of the whole mechanism. Special attention should be put on how
the double acting cylinders interact with the structure members to achieve the
functions described above.
A description of the pneumatic system, including the pneumatic components
you are using, a step-by-step explanation how the pneumatic system works using
the pneumatic system schematic diagram.
Project 7 is an individual
report for 7+2=9 points. To get an OK grade, you should write at least 2 A4
pages in English. I suggest that you pick an example with certain complexity
for this project.
