Team 5 Progress Report for Week 10
What has been done in the past week
Week 9:
Each team member created an initial concept drawing of a frame design for the solenoid. The
team reviewed each design and discussed which aspects of each person’s designs we
liked/thought could be improved. We decided that we can do risk reduction on the different
frame designs. We also discussed our research with our sponsor who gave us additional topics
to look into as we move forward. Joe began experimenting with solenoids to determine whether
or not the magnetic fields are uniform. As of right now, it appears as though the fields are fairly
uniform.
Feedback from meeting with sponsor
1. Reviewed individual frame designs to get feedback from sponsor
2. Sponsor suggested looking into the following parameters:
a. Distance (limits at centers of solenoids)
b. Magnetic flux density
c. Parameters to vary:
i. d/r (where d is the distance between two solenoids and r is the radius of
each solenoid)
ii. turn density (B = mu0…)
iii. mu0 (iron core or not)
iv. do not need wire gauges
3. Discussed optimization process:
a. Determine the effect of the iron core
b. Determine wire gauge
c. Determine number of windings need to produce required magnetic field
4. Testing
a. Obtain test equipment
b. Test homogeneity
c. Test field strength
5. Sponsor told us that the controls system should be our last priority
Feedback from last meeting with instructor
1. Professor Qi told us to feel comfortable using our budget early on so that we can
complete our project on time.
2. Reminded that we need to keep safety in mind with a project such as this since there is
so much possibility for harm (e.g. stemming from high currents, large weights, etc.)
3. Informed that we will likely not be able to machine parts personally next quarter but that
we can request parts to be made by the machine shop team.
Updates to powerpoint presentation slides
- Use of Visuals
- Introduction to topics and why soft robotics important
- Better project definition
Identify High Risk areas and focus on the most important risks
Read Research Article with research questions in mind
List your current concern according to the
importance
Risk assessment:
1. Determining if Iron cores effect magnetic field as expected
2. Optimize frame design and provide multiple variations
3. Determine homogeneity of magnetic field within helmholtz coils (simulation)
4. Determine stability (overheating) of coils operating for 5 min
5. Determine required frame materials for strength, magnetic properties, ease of purchase
What is the next step of your project
The team will do the risk reduction analysis on our frame’s design. We will proceed by building
prototypes of our leading designs and then run tests/analysis to determine design strength and
feasibility. We will also determine which materials are optimal to build the frame out of (i.e. with
respect to electromagnetic properties, price, and strengths of the materials).
Prepare Risk Reduction Presentation
Work on risk reduction:
● Jae Lee will look into frame / mount materials with respect to strength, accessibility and
magnetic properties
● Everbrook Zhou will look into the iron core’s magnetic properties
● Tanner Hanson will incorporate the heating analysis into the simulations and work on
refining the magnetic force simulations
● Joe Martin will work on refining the simulations and determining possible solenoid
geometry
Additional tasks:
Everbrook: start web page development (contact Ian Richardson)
Further research on core materials and safety with reaching out to Steve Roberts.
Budget Remaining: $500
