Design
MoCap markers are used to track the position and orientation of objects in the tank. They are attached to a rigid-body. Commercial Qualisys markers are relatively expensive and not very durable, despite being specified as waterproof. Therefore, custom markers as those in Fig. 10 are designed. The markers are 3D printed and laminated with reflective tape.
