PDR - EBox Redesign 2022/23
Project Scope
Main motivation to redesign the ebox is to accommodate new board/internals. Redesign electrical box to ensure adequate temperature management & monitoring for desert conditions. High temperatures within the electrical box can lead to overheating of electrical components (causing potential damage). Ebox should be dust/dirt-proof and provide exterior ports to connect to the rest of rover hardware.
Success Factors
Relevant Competition Rules
The maximum allowable mass of the rover when deployed for any competition mission
is 50 kg. The total mass of all fielded rover parts for all events is 70 kg.
Criteria | Constraints |
---|---|
Maintain airflow within ebox [check appropriate temp range] | Weight no more than 2.30kg when empty (weight of current ebox) |
Easy access to all internal components | Fit all components listed on List of Ebox Contents 2023 |
Temperature monitoring
IC: max temp 125 C
| Budget of $150
(https://www.protocase.com) - $2000 URC budget |
Organized wire routing
| Able to be manufactured in student machine shop |
Seal box to prevent dust/dirt from entering | Electrically insulate ebox from chassis |
Make as compact (yet accessible) as possible |
|
Design Improvements
Perhaps mount on side with filtered vents at top to allow heat to rise out from enclosure
Design Concepts
Pictures, sketches, low level CAD of design concepts
How would these systems work?
What are the risks associated with each individual design concept?
Design Proposal
If you only have one design concept, can merge with section above
What design concept do you want to move forward with?
Justify this decision by completing the following:
How could this design compare to established criteria and constraints? Is there risk associated with achieving any requirements?
How are identified design risks planned to be mitigated?
Very quick thoughts on what resources you may need to build and fabricate your design
What is your proposed project timeline?
Propose a CDR date
