Movie 1

This video shows the Northern quoll climbing the inclined platform. The inclined platform was a 90 mm wide plank of wood, covered in fine sandpaper (P120) to provide traction at a 38° angle, and represented a wide surface larger than the length of the hindfoot. Central to the platform is the force transducer (Nano-17 titanium, ATI instruments) placed level with the trackway, with a 90 × 90 mm platform attached to it. The Northern Quoll strikes this platform with the front left foot, then both hindfeet.
