Finishing the Zima arm rework

Zima · 2025-12-04 · 8 hours

Goal: Have a fully functioning gripper capable of lifting medium sized objects (~0.5kg max, 10cmx10cmx10cm)

What I did:
- Finished designing, printing, assembling, and testing zima's new arm
- note: arm has been reduced to 4DOF arm + 1DOF gripper (5DOF total), down from previous 5DOF arm + 2 DOF gripper (7DOF total)
- Tested and iterated on new camera mount, ensuring gripper + workspace is in frame

What worked:
- Zima with new arm
- zima arm v2
- *Wrist mounted camera POV
- Pasted image 20251204214941

What failed:
- wrist camera FOV is quite low (~60 degrees), resulting in camera mount needing to be quite far back from the gripper

Key learning:
- N/A

Next session:
- Begin PCB redesign
- Make a list of all new features needed (eg. battery monitoring, oled screen?)

Time spent: 8 hours
