Teams

Here at M-STARX, we are one big exoskeleton family and we all have a role in bringing our designs to life. We participate in two competitions, one being the Applied Collegiate Exoskeleton Competition (ACE) and ASTM International Exo Games, therefore we have two different teams to cater to each exoskeleton. Even though we are split into two competition teams, there is extensive overlap in collaboration. From sketching to design reviews to manufacturing, we support each other through it all no matter what subteam we are a part of. 

Algorithms (Electrical/Programming)

The Algorithms subteam aims to improve the current reactive (non-cyclical) and walking cyclical algorithm on RALPH 2.0. We consult experts in the field of powered human motion and perform research to design new or improved algorithms for different pilot modes. Through research and consultations, we aim to develop additional predictive algorithms for new modes of operations for movements such as stair climbing, crouching, pulling weights, kicking, etc. We also want to introduce switching between different predictive cyclical modes and a standard non-cyclical control system, to be interfaced with an arm monitor. 

Arm Monitor (Electrical/Programming) 

The Arm Monitor subteam aims to design and complete the fabrication of a wearable, interactive digital monitor for pilots to use during competition that displays vital systems of the exoskeleton. The arm monitor will interface with the Algorithms team to allow the pilot to select different drive modes. The goal is to develop an intuitive Graphical User Interface (GUI) for the pilot to use easily and quickly while performing tasks at competition

Improvement and Optimization (Mechanical)

In I&O, the aim is to repair and improve RALPH 2.0 for its new performance in ACE 2026 – redesigning and changing out mechanical parts which don’t perform so well and improving existing parts. We are also improving the integration of wiring on the exoskeleton all around, and integrating vital monitoring systems on the exoskeleton like temperature sensors. In addition, I&O aims to design a new, secure containment of our lithium-ion battery and its electromechanical disconnect.

Team 2027x (Mostly Electrical/Programming for 2027)

Team 2027x aims to design and fabricate the next generation exoskeleton! Team 2027x will intelligently use a lot of functional design elements from previous exoskeleton iterations to design a new powered lower-body exoskeleton to compete in ACE 2027. We aim to design a new structure for powered hip and knee joints, and unpowered back and ankle joints, manufacturing as many parts in-house as possible. The goal is to learn and implement more advanced design techniques and practices, building more efficient parts with better ergonomics, adjustability, and power-weight ratios.

Testing Team (Research)

The Testing team aims to design better methods for M-STARX to test our designs without having a physical exoskeleton and pilot. We will develop a simulation which will accurately reflect key movements of an exoskeleton with inputs of an algorithm, which can give live feedback to future M-STARX programmers. The goal is to develop a very simple physical structure for programming and electrical teams to test exoskeleton motion algorithms on without the need of a pilot, as well as a very clean and easy to use structure which pilots could wear to collect data without wearing an exo.

Biomechanical Optimization (Research)

The Biomechanical Optimization subteam will be collecting diverse biomechanical data to influence decisions in optimal pilot movement and improve an adaptable mechanical design to quantify additional force requirements for lifting and stepping motions. We will use MATLAB/COMSOL to run simulations of different pilot movements and identify key stages in gait and upper body movement. We want to produce an individual or a multipurpose algorithm that addresses: walking, crouching, sitting, and running. Additionally, any other movements required for the four test stages: firehouse carry, confined space navigation, overhead halligan tool use, EMS vehicle rescue. We aim to produce a simulation that mimics simplified/key exoskeleton movement to allow testing of components before worn by the pilot. 

Mechanical Fabrication (Mechanical)

The Mechanical Fabrication subteam aims to design and manufacture upper body support for both arms that are fully mechanical. We will consider 4 testing methods and attachment of battery/electrical housing, as well as user strain (back and arms) with lifting movements, biomechanical optimization research, comfort for 4+ hour shifts, and the additional load of wearing first responder gear. This subteam will design and manufacture customizable thigh plates and waist attachment and research more compact transmissions systems and optimal motor integration with leg supports. We will also consider attachment to the upper body and providing mechanical support when motors are turned off. Research on materials for lightweighting, battery/electrical compatibility, user comfort during high intensity movement, durability, etc. will be crucial. 

Motors and Electrical (Electrical/Programming)

The Motors and Electrical subteam will identify and research motor alternatives that are compact and easily attainable. We consider battery placement, safety ejection, and circuit design/configuration on the exoskeleton. We aim to design and construct modular electrical components design that can be easily accessed and detached from the exo. We will work in collaboration with Mechanical Fabrication for alternative fixtures. In addition, we are responsible for collaborating with the Biomechanical Optimization team to identify torque required and placement of IMUs and other sensor components. We are to design wiring schematic for the entire exo and attachment/securement methods that don’t interfere with the pilot’s motion path.
