2021-01-05 Meeting Minutes - First Meeting of Term

Welcome to 2021!

I hope everyone had great holidays!
Lots of work to be done to get ready for SAR
Lock-down in Ontario
Please turn your webcams on for meetings (don’t worry if you don’t have one)

What is SAR?

SAR (System Acceptance Review) is a package sent to URC which is judged against all other packages sent by other teams in order to select which 36 teams will be competing in the field
Due March 5th
Consists of both written and video components
Our video from last year: https://www.uwaterloorobotics.com/competitions?wix-vod-video-id=ab19f6978db94ae0af27b1496993cecc&wix-vod-comp-id=comp-kau0rm5t

SAR planning document

Tasks to be done for SAR

Get a working robot!
1. Finish the e-box
2. Gimbal Assembly
3. Arm Assembly
4. Science mechanism assembly
5. Base station assembly
Test the working robot!
1. All mechanisms working smoothly and as expected
Produce the SAR video and required documentation

SAR Milestone Plan Overview

Week of Jan 4-11:

Order all parts that need to be ordered
start planning SAR video

Week of Jan 11-18:

Start arm, gimbal, assembly using parts that have already arrived
Continue planning SAR video

Week of Jan 18-25 :

All parts for assembly should have arrived, so finish robot assembly
Continue planning SAR video

Week of Jan 25-Feb1 :

integrate electrical components (e-box assembly, PCBs, wiring, etc)
Test all mechanisms and motors

Week of Feb 1-8 :

Film SAR video
write SAR documentation

This gives us a month of slack to work with in case we run into problems, and also gives the other subteams room to work with..

Beyond SAR

Clean the club’s room in the Bay (also take inventory of everything in there)
Drivetrain revamp
Find any issues with the current design of the rover and start work on addressing them (or look into how to improve current systems)
Prepare for competition this summer (June 3-5 in Utah)
Documentation of existing systems
Look into an obstacle course for the rover
Any suggestions?

Rehnuma Tasneem		Figure out what camera is being used in science for the camera mount
Max Apitz-Grossman	E-box baseplate finished	Still need to figure out a quick release system for ease of removal of the e-box Pins probably from mcmaster carr
Medina Colabrese	Collected information about wires used for each of the sensors and motors on the arm	Cross-reference with diagram from Tony to make sure I didn’t miss anything Determine wire lengths and required harness sizes
Abdul Haseeb	Fixed the gimbal mate and removed a repetition that appeared in the other main assembly Removed the 2021 design for the drive train as its no longer being used Small electrical component in gimbo is not able to be deleted for some reason	imma do what Asha tell me

Emily Adam	Returning to the team :)
Andrew Zhang		Finish arm model Collect rotational inertia data

Lessons Learned in 2020

Drafting channel worked well
Good grabcad etiquette is important
Reverting grabcad changes is great
More comments into the changes when uploading to grabcad
Do thorough design reviews
Not enough inter-subteam communication

Goals

Calculate center of mass in solidworks for new design
Maintain everything in metric units as much as possible
Solidworks PDM
Solidworks workshops for stress analysis and FEA
Go to URC

University of Waterloo Robotics Design Team
