WayBionic — ROS2 Ground Station
A ground station for remote visibility and control of a surgical robotic arm, with motion tests publishing to a simulated joint-state driver.
MY CONTRIBUTIONBuilt the movement-test panels and diagnostics behavior that surfaces stale joint values and errors inside RViz; changed the arm wiring to match the control code.

I built the movement panels and the errors they surface.
The monitor checks joint and system state, then reflects stale values and errors inside RViz instead of hiding uncertainty. Motion tests stay controlled until the real arm is ready.
