Convert the uploaded robot-arm sketch into a crisp engineering schematic without changing its topology. Show a six-axis serial manipulator, label joints q1-q6 and links L1-L6, add right-handed coordinate frames, dimension callouts, reachable-workspace boundary, and a dashed end-effector trajectory. Include a small Denavit-Hartenberg parameter-table placeholder. Use consistent strokes, unambiguous arrows, high-contrast labels, and a light technical-grid background.
