2020-05-09 Meeting Minutes - Gimbal Design Specs
Project Members
Nathan Allen, Cole Myers, Caleb Tsen-Tham, Alex Roman
System Definition
Aim camera towards desired direction and maintain pan, pitch, and roll orientation relative to inertial frame (ground). Gimbal must be able to continuously turn in the pan-axis indefinitely
Goals
General:
Durable, requires minimal to no maintenance
Small profile
Can rotate camera quickly to stabilize in real time
Specifics to Optimize:
Minimize Weight
Maximize Angular acceleration and speed of each of gimbal (within context of estimated rover’s maximum angular velocities)
Minimize Cost (re-use components)
Minimize manual manufacturing (3-d printed solutions preferred)
Minimize size
Constraints
Must use USB 3 slip-ring on pan-axis to facilitate continuous rotation
Tilt, Roll axis must have sufficient torque to maintain angle at maximum moment arm lengths
Must be able to mount to horizontal beam used to mount antenna (current gimbal mounting points)
Criteria
Fewer components preferred
Simple assembly preferred (adhesives, locking joints, friction welding preferred over fasteners)

Slip-ring drawing
Linked gimbal is not servo driven, our gimbal needs to be driven by servos.

Note
To Do
Pick Servo for roll (https://www.servocity.com/) (Nano, Micro, Sub-Micro | Analog Signal (PWM))
Max 5/6V, Check Torque Rating on BlackFly
Account for weight of BlackFly
