It's all relative, so write down relative to what. An isometric robot cell with a world frame {W}, the robot base {B}, the tool {T}, a camera {C} and an object {O}, each with its own x / y / z triad and dashed transforms between them, signed off with T_WT = T_WB · T_BT and a reminder that matrices don't commute.

What you get

  • Front: Left-chest 3D coordinate frame (x orange, y cyan, z black) marked {W}, "Know Your Frame · Of Reference · {W} → {T}"
  • Back: Large "KNOW YOUR / FRAME OF REFERENCE" header over an isometric floor grid with an orange robot arm, a camera on a pole and an orange box, frames {W} {B} {T} {C} {O} with transform arrows T_WB, T_BT and T_CO, and an equation bar: T_WT = T_WB · T_BT, "Multiply in order. Matrices don't commute."
