Guardian® XO® Frequently Asked Questions
Yes. The Guardian XO exoskeleton can be used in both indoor and outdoor settings in temperatures ranging from -4 °F to 115 °F (-20 °C to 46 °C).
The exoskeleton is a wearable robot that can be donned and doffed while docked in the XO Pod docking station. This process typically takes less than 30 seconds.
The exoskeleton can be securely stored in the XO Pod Docking Station.
If an operator needs to take a break, they simply return the exoskeleton to the XO Pod docking station to doff the suit. Taking the suit off can be done in less than 30 seconds.
When the battery charge drops to a pre-configured threshold, the exoskeleton will provide both a visual and audible alert through the operator control interface (OCI). Battery charge threshold settings can be configured upon request.
The exoskeleton can lift and manipulate up to 200 lb (90 kg) repeatedly without exertion, strain, or injury.
Yes. The Guardian XO exoskeleton has 24 degrees of freedom or rotational joints. The degrees of freedom in the shoulders allow the robot’s arms to be raised and lowered – front to back, as well as laterally – similar to the range of motion of human shoulders.
An operator in the exoskeleton can walk at about 3 mph (4.8 kph), an average walking pace for a human.
In order to navigate work areas, the exoskeleton is designed and tested to execute a single step-up or step-down on a 10” (25 cm) tall step.
The exoskeleton is designed so that the human operator bears none of the suit or payload weight. However, for better payload context and operational safety, a percentage of that weight can be optionally felt by the operator to offer a safer, more optimal operator experience.
Three hot-swappable lithium-ion batteries power the exoskeleton. This allows for near-continuous operation.
The exoskeleton is designed to operate near-continuously with hot-swappable batteries.
The exoskeleton batteries automatically charge when the suit docks in the XO® Pod Docking Station. An optional standalone charging station can charge batteries as well.
A quick-connect interface allows end-effectors to be connected or removed quickly and easily from the exoskeleton arms.
The exoskeleton is IP65 rated, which protects against dust ingress and water. This allows the exoskeleton to be exposed to rain and outdoor elements and cleaned with high-pressure water jets.
Yes. The exoskeleton has a hands-free mode allowing the operator to lock the suit’s arms. This feature enables the operator to use their human hands while simultaneously holding a heavy load, which effectively allows them to perform tasks that traditionally would take more than one person to accomplish.
The exoskeleton has an operator control interface (OCI) mounted on the arm, which interfaces with the suit’s control system. The OCI enables the operator to turn the robot on/off and view key diagnostic readings and alerts.
Appropriate work clothing, safety shoes, and standard PPE (e.g., head protection, gloves, eye, and hearing protection) as dictated should be worn when operating the exoskeleton.
When the exoskeleton detects a load weight that exceeds the 200 lb (90 kg) limit, it will generate both a visual and audible alert through the operator control interface (OCI) to notify the operator.
Yes, the Guardian XO is a wearable robot designed to operate safely in the proximity of other people. Like any piece of large mobile machinery or tool used where people are present, Sarcos recommends operating the robot in a specified workspace with ample safety clearance.
As a part of Guardian XO authorized operator training, users will receive instruction on how to safely operate the robot and exercises designed to help the operator accomplish various tasks with the suit.
The Guardian XO exoskeleton operates on three batteries, which can be recharged either by docking into the XO Pod docking station or via an optional standalone battery charging station. The XO Pod docking station requires a 30 A power supply and comes equipped with 120 V or 240 V power cables. The docking station requires a connection to a LAN or Wi-Fi network for periodic software updates and customer-prompted data retrieval.
Guardian XO operational data is stored locally on the robot and transferred to the XO Pod docking station when docked. Sarcos uses government encryption protocols to ensure the protection of operational data.
