Calibration

Home Calibrated

All joints calibrated to home position. Dashboard uses home-relative degrees (0° = home). Slider limits are ±180° for visualization — actual mechanical stops are narrower and enforced in config.yaml on the robot.

Home: J1=702.97° J2=34.53° J3=-185.14° J4=485.65° J5=1084.42° (absolute encoder)

Model

URDF v2 CAD Model

Loaded from ASSEMBLY.urdf (v2) — 16 STL meshes, 5 revolute joints. Upper arm 247mm, forearm 247mm — matches physical robot. Joint axes and link offsets from Charan SOLIDWORKS export.
