  • Project Mission Statement: Micro-g’s mission is to develop tools for NASA which will be

used in a micro-gravity environment. The end goal is to generate new technology that will be used in future spaceflight missions, having a significant impact on the world of manned spaceflight.

  • Project Objectives: The objective of Micro-g is to design, manufacture, and test an

Extravehicular Camera Mount to be used by NASA. For this semester, the team will submit a Test Equipment Data Package, Proof of Concept Video, and Test Readiness Review prior to traveling to Houston for the final test week in the Neutral Buoyancy Laboratory (NBL).

DESIGN OVERVIEW

Prototype V2 Prototype V3

Spring 2019 Make to Innovate (M:2:I)

slide-19
SLIDE 19

PROTOTYPE V2

  • Two switches engage/disengage the

pawl

  • Springs provide the tension to create

the moment to hold the switch in locked/ unlocked position

  • If one switch fails, the other can still

lock the mechanism

Make to Innovate (M:2:I) Spring 2019

slide-20
SLIDE 20

PROTOTYPE V3

  • One switch to engage/disengage the

pawl

  • Constant force spring on the other side of

the double gear

  • If the one fails the other is able to keep

the clamps shut

Constraints

slide-22
SLIDE 22

DESIGN CONSTRAINTS

  • With Micro-g’s budget, the EVA camera

mount will be manufactured from cheaper test-ready materials

  • To be consider for flight, the camera

mount was designed to fit all three interfaces

Spring 2019

Micro-g NExT Requirements

1

The device shall attach to at least two of three interfaces

2 The device shall include a 1-fault tolerant attach method 3 The device shall use only manual power 4

The device shall allow for camera pitch and yaw adjustability of ±45˚

5

The device shall be able to pack within 12" x 16" x 18"

6 The total must be less than 15 lbs. 7 Device shall be made from NBL approved materials 8 Device shall allow a GoPro to mount to it 9 Pinch points should be minimized

DESIGN REVIEW

Current Design

slide-24
SLIDE 24

CURRENT DESIGN

  • Decided to continue with prototype V2

due to constant spring causing issues

  • Reduces pinch hazard caused by

constant spring

  • Simpler to assemble

Spring 2019 Make to Innovate (M:2:I)

slide-25
SLIDE 25

CURRENT DESIGN

  • Current design uses a double gear
  • Larger gear moves both sliding arms

the same length and in the same direction

  • Pawl engages smaller gear to lock the

sliding arms from opening while attached

DESIGN REVIEW

Proposed Changes

slide-27
SLIDE 27

PROPOSED CHANGES

  • Removed away from pin design
  • Added switch system instead of

traditional ratcheting system

  • Removed end of the sliding arm

to ease manufacturing/assembly

Design Risks

slide-29
SLIDE 29

DESIGN RISKS

  • Risk 1: Missing NASA deadlines for Micro-g NExT
  • Mitigation 1: The Micro-g timeline has been advanced
  • Risk 2: Key component failing during testing at the NBL
  • Mitigation 2: Conduct comprehensive testing and analysis prior to May
  • Risk 3: Design flaw resulting in failure to meet requirements
  • Mitigation 3: 3D print and test prototype version prior to final build
