• N/A

A5/A6 - Encoder Protection

• Encoder Protection - A5/A6

  • Printing enclosure design

• Will test and install tomorrow

Design Allen Key Tool Module

• Good for new members

Joint Testing Plans

• Need to develop plans to measure torque output, backlash, speed, efficiency, current draw for each arm joint

• Plus verify end stop functionalities

• Will start after midterms, when odrives work

• Good for experienced members who are familiar with motor properties and motor controllers

@Chanpakorn Chaiklahan

Arm Camera Mount

• Select a suitable camera to be mounted on the wrist

• Requires communication with SW, simpler mechanical design task

Circle back on this one

Science Assembly

• Assemble drill module to air manifold system routing

• Additional components ordered from McMaster

• new t-slot parts are being machined

• Risk of binding for air manifold mechanism

• continue assembling main frame and air manifold

• tested binding and servo motor that lifts the air manifold

Science Sensor Dino Mount

• Dino mount is completed

• Parts are printed

•  

• Assemble, test and install dino mount

Air Manifold Assembly

• Assemble air manifold

  • @Austin Tailon Huang

• Air manifold assembled

3D Sensor Head Mount

• Design and assemble 3d printed sensor head mount

• Testing on CO2 sensor completed

  • CO2 sensor can work when submerged or in a vacuum

• Clarify what she means by vacuum

• She thinks 15sec submerging can work

Remachine Science Dirt Nozzles

• Science - Remachine the air manifold nozzle heads

• Revisit when science is fully assembled

Fix Linear Carriage for Science Mechanism

• Science - Fix the test tube rack linear actuator

• Nut superglued in place

• Initial solution did not work,, reassign and redesign

Design Mount for Science PCB

• Good for new members, learn about PCB packaging

• Easier design task
