2021-04-23 Meeting Minutes - General
Establishing Length Requirements
- Determine max arm reach/workspace(max vertical reach above ground, and distance above drivetrain)
- Joint configuration
- Function of arm (what kind movements does it need to complete?)
- what linkage length ratios are required
- define our workspace
- chassis/drivetrain height?
- Can we establish hard numbers on next sunday?
Axis Configuration
- 6 axis articulated arm, but for next meeting we need to figure out the joint configurations
- What are the best joint configurations for high load applications?
- we need a better idea of how the turntable should work
Camera Placement
- Where do we want to place the camera?
- it should not rotate with the end effector
- Look into gorilla tripod type leg things
- Do we need a gimble? Static cameras? How many cameras are required on the arm? Should we just put a shitload of static cameras on the rover?
- Should joint design be configured to allow the end effector to "look back" on the robot?
Motors And Actuators
- Look into maxon motors
- Look into linear actuators
- Look more into solenoids
Joint Drives
- finish reserach into the rest of the joint drives, and look more into OTS options
Encoders (In the Future)
- Look specifically into RLS and Netzer available options
- Reach out to Cindy to design a fixture for netzer testing
Arm Mounting
- Further investigation required into the extrusion to slide the arm on would be great
End Effector
- High allen key torque is probably not necessary for high torque
- pitching axis 5 for allen key is cool
- solenoids offer an interesting solution for key pressing, lets look into it more
- (we already do this) but USE BALL HEADS
- Investigate pneumatics
- Look at urethane sheets on canada composites (PBLT vs shore hardness?)
- Compliance is super important
- TWO finger design has been confirmed
- look into compliance geometry on fingers
- look into feasibility of switching fingers between missions
Linkages
- plastic casing is unnecessary
MAIN PRIORITY GOALS
- figure out linkage lengths
- Conceptualize end effector configuration
- Figure out joint configurations
- Research axis 1 "turntable design"
- flesh out the research listed above
