Robot-Assisted Movement Biomechanics

The NERVE Center’s Movement Assessment and Performance (MAP) Labs is used to evaluate the movement of humans, robots, and human-robot systems. Lab equipment includes a Motek M-Gait instrumented split-belt treadmill, Vasper aerobic exercise machine, motion capture systems, and force plates.

The NERVE Center works with the U.S. Army Combat Capabilities Development Command Soldier Center (CCDC-SC) to evaluate exoskeletons that assist warfighters by alleviating the burden posed by carrying heavy loads out in the field.

With support from the National Institute of Standards and Technology (NIST), NERVE assists in the development of test methods to evaluate the performance of exoskeletons towards ASTM F48 Committee on Exoskeletons and Exosuits standards. For example, the NIST Position and Load Test Apparatus for Exoskeletons (PoLoTAE) is housed at NERVE to evaluate the performance of upper body exoskeletons.

Grasping and Manipulation

The NERVE Center houses a robotic manipulation testbed, named the ARMada, comprised of a variety of robotic arms, end effectors, and sensor systems.

The ARMada is used for developing test methods that evaluate grasping, collaboration, and assembly capabilities used for industrial automation tasks. In collaboration with Oregon State University (OSU), the ARMada testbed will be remotely accessible for outside users to schedule and conduct benchmarking tests via the Remote Experimentation of Manipulation for Online Test and Evaluation (REMOTE) Project.

The NERVE Center develops metrics and evaluation methods for industrial robotics to support the Advanced Robotics for Manufacturing (ARM) Institute to measure performance, efficiency, productivity, and versatility. NERVE also works with the National Institute of Standards and Technology (NIST) to develop test methods to measure elemental grasping and functional assembly performance of robotic manipulators.

The NERVE Center now provides YCB Object Sets, a standard set of objects used for benchmarking robotic manipulation. The set consists of common objects of varying shapes, sizes, textures, weight, rigidity, and some widely used manipulation tests.

Industrial Mobile Vehicles

The NERVE Center develops test methods to evaluate the capabilities of automatic, automated, and autonomous unmanned ground vehicles (A-UGVs), which includes both automatic guided vehicles (AGVs) and autonomous mobile robots (AMRs). Mobile systems from the ARMada are used for development, such as those from Fetch and Omron.

NERVE develops standard test methods for these types of vehicles in collaboration with the National Institute of Standards and Technology (NIST) in support of the ASTM F45 Committee on Driverless Automatically Guided Industrial Vehicles. Test methods include those to evaluate navigation, obstacle avoidance, docking, and localization capabilities.

A malleable test environment is utilized that can evaluate navigation capabilities by adjusting the layout of its boundaries, implementing obstacles (positive, negative, overhead), environmental conditions (e.g., lighting interference), and varying misalignments between the A-UGV’s internal model of the environment and the true physical nature of the environment.

Physiological Measurement

The NERVE Center utilizes a suite of biometric sensors for physiological measurement of the physical and cognitive state of various human functions. These sensors can measure the impact of wearable technologies on a person, such as personnel protective equipment (PPE) or exoskeletons.

Sensors include those for measuring muscle activity (EMG), movement (IMU), oxygen consumption (VO₂), heart rate, skin and core temperature, and cognitive load (fNIRS).

The NERVE Center works with the U.S. Army Combat Capabilities Development Command Soldier Center (CCDC-SC) to evaluate the physiological effects of wearing bomb suits -- those for protecting individuals during explosive ordnance disposal (EOD) operations -- on a person. NERVE is also collaborating with Worcester Polytechnic Institute (WPI) to develop methods for evaluating cognitive workload of a human team and utilizing the signals to improve human-robot interaction.

Legged Locomotion

The NERVE Center conducts research on legged robot systems, which include human-worn exoskeletons, humanoids, and quadrupedal robots.

The NERVE Center houses an Agility Robotics Digit humanoid robot for conducting research on legged locomotion control. The MAP Labs facilities (see above) are also utilized for robotic walking experiments.

Previously, the NERVE Center housed the NASA Valkyrie humanoid robot in support of the Space Robotics Challenge (SRC) and human-robot interaction methods for humanoid robots used for disaster response tasks at the DARPA Robotics Challenge (DRC) were studied.

Response Robots

The NERVE Center houses test methods for response robots, meaning those used for urban search and rescue (USAR) and explosive ordnance disposal (EOD), collaborating with the National Institute of Standards and Technology (NIST) to develop these test methods.

Standard test methods are specified through the ASTM E54.09 Committee on Homeland Security Applications; Subcommittee on Response Robots and are used to evaluate robot capabilities and measure operator proficiency.

These test methods apply to ground, aerial, and aquatic robots, organized into suites including mobility, dexterity, maneuvering, situation awareness, sensors, and safety.

The NERVE Center's focus is on test methods for human-robot interaction evaluation, such as those that highlight an operator's decision-making capabilities that could be assisted by effective robot autonomy techniques.
