Modular Load Exoskeleton 2 (Lexo 3)
Most recently we've been at work improving MLX, or our Modular Leg Exoskeleton. Our redesign primarily involves integrating multiple control modes (Transparency, ANO, and Virtual Model) and targeting the Human Factors of our Exo, such as fit, Don/Doff process, and safe extraction of the battery pack in case of danger. Additionally, we've been working towards a new, modular harness that can be used for most Exo's we try to build in the future. While our redesigns are still in progress, we were able to make enough progress this year to secure 2nd place at the 2022 Ace Competition!
Modular Load Exoskeleton (Lexo 2)
Our project from 2018-2019 was improving upon our Leg Exoskeleton. MLX, or the Modular Leg Exoskeleton is a newer, better version of Leg Exoskeleton (LEXO). The hip and joint actuation have been updated and are designed to assist general movement and double strength. It features an active joint design to actuate every joint in motion so it won't feel like you are moving the exoskeleton. This project competed in the 2019 Applied Collegiate Exoskeleton competition and won first place.
Our project from 2016-2017 was a load-bearing leg exoskeleton called Lexo (Leg Exoskeleton) designed to offload a weight of at least 70 lbs to the ground. While offloading the weight, it still allows the user to move in the same way as without the suit, completely unhindered. The suit is designed to help with emergency rescue workers who need to carry large amounts of equipment on their person. The ultimate goal of the suit is to reduce the strain on the user as well as the metabolic cost of walking with the suit and weight as opposed to just carrying the weight itself.
Carries a payload of 100lbs
Several hour battery life
Allows for same range of motion as healthy adult
Adjusts to heights between 5'8"-6'2"
Single Arm Motorized Exoskeleton
Built in 2015, SAM-E is the first prototype of our upper-body exoskeleton system. It was designed with the goal of increasing the strength of the elbow proportionally to muscle signals from the biceps and triceps.
Ultimate goal to give 30 lbs of extra lifting strength
Does not require the use of buttons/switches to control
Costs approximately $1000 in materials to make
Has electrical and mechanical stops to ensure the suit cannot injure the user under any circumstance.
