Nansense R2 Suits

NANSENSE R2 Suits are professional, inertial full-body motion capture systems—or mocap for short. Sensors located on the suit measure the orientation of individual body parts, and NANSENSE Studio software transforms the data into a digital skeleton animation.

The system requires no optical cameras, markers, or a dedicated studio. It can operate wirelessly or wired, indoors or outdoors. Three configurations are available: Indie, Pro, and BioMed, differing in the number of physical sensors and the accuracy of the representation of individual body segments. 

Operation
Each R2 sensor contains: a gyroscope, an accelerometer, and a magnetometer.

Based on the data from these components, the system determines the orientation of body segments. The software then uses the skeletal model, kinematics, and physical simulation to interpret gait, running, jumping, sitting, foot contact, and height changes.

This is an inertial system, so there's no problem with markers being obscured by other people or objects, which is typical of optical systems. At the same time, the system doesn't measure the actor's absolute position as precisely as a properly configured camera studio. The manufacturer explicitly mentions the possibility of positional drift, which must be compensated for in software or mitigated using additional trackers.

Available Configurations

NANSENSE R2 Indie

The basic version is designed for independent creators, small studios, and educational institutions.
15 R2 sensors on the body,
the remaining motion segments are partially calculated kinematically,
the set includes a suit, hub, 15 sensors, a battery, and a router.
When connected to the Indie gloves, the system utilizes a total of 29 sensors.
Best Uses: Motion Capture training, game prototyping, basic character animation, simple VR projects, and research that does not require a large number of independently measured segments.

NANSENSE R2 Pro

The production version is primarily designed for professional animators, game studios, film, and television.
18 R2 sensors on the body,
more detailed motion representation than the Indie version.
the set includes a suit, hub, 18 sensors, a battery, and a router.
When connected to the Pro gloves, the system utilizes a total of 40 sensors. Best Use: Animation production, pre-visualization, real-time character animation, games, films, broadcasts, and digital avatars.

NANSENSE R2 BioMed

The most advanced version, focused on biomechanics, ergonomics, sports, and motion studies.
22 R2 sensors on the body,
extended spine and shoulder girdle motion measurement,
the set includes a suit, hub, 22 sensors, a battery, and a router.
When connected to BioMed gloves, the system utilizes a total of 50 sensors.
Best Use: Research laboratories, biomechanics, workplace ergonomics, sports analysis, artificial intelligence, and robotics research.

The manufacturer emphasizes, however, that the system is not a medical device. Therefore, it should not be considered certified diagnostic equipment or used alone for clinical decision-making.
