The KineMouse wheel is a light-weight running wheel for head-fixed locomotion in mice that allows 3D reconstruction of the position of the body with a single camera.
The transparent floor and a mirror mounted inside at 45°, allows you to capture two orthogonal views with a single camera, enabling 3D reconstruction of body kinematics with a high-speed camera. The open source DeepLabCut software will then automatically track the paws and tail with high accuracy.
Since the wheel is primarily made of acrylic and polycarbonate it is lightweight, allowing mice to run quickly and happily.
