The EXE ARM, a new tool for Disabled persons and Construction!

(The following is an ICly pamphlet that advertises the EXE ARM. It continues as follows.)

MOON TECH keeps up the pace!

Our team is designing an untethered, powered, upper arm exoskeleton for use in the fields of rehabilitationand the****utic application, as well as occupations requiring augmented strength. Though systems exist, past exoskeleton endeavors have led to bulky, expensive, invasive, and tethered solutions. The challenge is to build an exoskeletal augmentation system that is inexpensive, streamlined, and wireless.


Our solution is unique in that it will be a low-cost, ergonomic device actuated through sensors measuring the user’s motion. Through onboard sensing, the skeleton can provide rich data, such as range of motion for use in physical therapy. This data can be used by doctors and patients to more accurately track improvement over time. With its low cost, hospitals could employ multiple devices and aid a larger audience of patients; the devices could even be used at home for physical therapy, which would dramatically increase quality of life for patients.

Outside of physical therapy, augmented strength is applicable to physically intensive occupations, as well as search and rescue operations. Each year, thousands of workers must take leave due to injuries triggered by heavy lifting (being able to lift sixty more pounds than you normally can!); with augmented strength, workers could avoid harmful situations. This is how we work.

What does it do?
The bionic device, called the EXE ARM, is the brainchild of our mechanical engineering developer "Geo" who, in their final undergraduate year, built an upper-body exoskeleton that can be used in physical therapy and manual labor. The EXE ARM straps directly to a user's right arm to help lift heavy objects that the user wouldn't normally be able to lift. Its inventor believes that it will be useful in aiding physical rehabilitation, both for people who have suffered upper body injuries and for those with previously existing muscular-skeletal disorders.

"With the EXE ARM, we wanted to create something that could both augment a user's natural strength as well as help someone perform physical therapy in their own home," says Calliope Speedwagon, the Titan Arm's inventor. "I wanted to create something that was low-cost and easy for a user to put on and strap to themselves."

According to the United States Department of Labor, back disorders are one of the leading causes of disability for people during their working years. The American National Institute for Occupational Safety and Health says that back problems afflict over 600,000 employees each year with a cost of around $50 billion annually to the U.S. economy. The problem is significant in other countries: the World Health Organisation says that worldwide, 37% of lower back pain is due to injuries sustained in the workplace.

How do you wear it?
Callie says that addressing this problem while being attentive to user comfort was one of the primary motivating principles in designing the device: "We wanted something that was comfortable for the user, something that mimics the body's natural mobility and range, so we definitely went through a lot of testing in order to get to where the design is right now."

"The EXE-ARM attaches to a user's right arm with a power motor at its elbow joint. The bionic limb can lift approximately 40 pounds of weight, augmenting a user's natural strength. The arm is predominantly made of titanium and steel components, and is powered by a DC battery."
