DIMLab - Design of Innovative Machines Lab

The Design of Innovative Machines Lab (the DIMLab) is home to the design team led by Dr. Drew Murray and Dr. Dave Myszka of the Mechanical and Aerospace Engineering Department. The primary goal of the team is to create, design, build, and test novel machines and mechanisms for a variety of applications while generating the theory that supports these innovations. The DIMLab is in Kettering Labs, room 143, on the University of Dayton campus.

The statically equivalent serial chain (SESC) is a way of visualizing and tracking the center of mass. Once the SESC is constructed, the center of mass is located from the kinematics alone, and no force plates or sensing of other data is needed. The mannequin in the video above shows this principle utilizing some sweet dance moves (crank up the sound!). Seen below, the actual mannequin was recently tested in the Motion Analysis Lab (Fitz Hall room 220F) and we're hoping to compare the data to the model soon!


The next five images are from Noel Michel's honors thesis project. Noel is modeling weird and paradoxical spaces described in short fiction.
The three images above are from Jorge Luis Borges's "The Library of Babel." In it, he details a library that is seemingly infinite in scale (it has more books than there are atoms in the universe!) yet is actually finite.

Frank Kafka wrote a short(-ish!) story called "The Burrow". The narrator describes an underground lair that he has fashioned himself.

The DIMLab is currently working with a team at the Labatoire d'Informatique, de Robotique et de Microelectronique de Montpellier (LIRMM) in France. The goal is to develop tricycles powered by FES stimulated leg muscles in drivers with para- or tetraplegia. The official site for the project is freewheels.inria.fr. The video below shows one of the concepts for modifying the pedaling mechanism.

This is a video of mechanism for extending an orientable solar array away from a 3U cubesat. The video was made by Ben Millard and Dillon Balk. The video was to assist Justin Ehren in presenting the modeling work he did for his honors thesis on this topic.
The DIMLab has a long standing interest in shape-changing mechanisms. A concept for a morphing wing using tensegrity is shown below.

On July 26th, Drew Murray gave an invited presentation in Shanghai, China at Shanghai UniversityThe title of the talk was "Designs with Many Moving Parts - The Links Between Things." He was hosted in Nanjing by Feng Feng (Jeff) Xi and Yingzhong Tian.

On May 1st, Yucheng Li was awarded a Graduate Student Summer Fellowship. These awards are from the Graduate School at the University of Dayton and provide a stipend for the summer!

On April 24th, eleven DIMLab members presented their research at the Stander Symposium: 
  • Austin Mills - Assessment of Tensegrity-Based Aircraft Wings Capable of Morphing
  • Yucheng Li - Spatial Chains for Matching 3-Dimensional Curves
  • Andy Bazler & Bennett Snyder - Design of a Trike for Paraplegic Use with FES
  • Ben Millard & Dillon Balk - Design Modeling of Various CubeSat Solar Arrays Configurations
  • Justin Ehren - Energy Analysis and Orbit Simulation of Actuated CubeSat Solar Arrays
  • Matt Deters & Zack Jordan - Linkages In Mechanical Presses That Produce Substantial Dwell
  • Alex Seither & Ian Melnyk - Tracking the Center of Mass of a Human Using a Statically Equivalent Serial Chain
