Thank you for the very positive response at IDETC for this worksheet.  This post is mostly to make it easier for those who attended IDETC to find the Design for Additive Manufacturing Worksheet. Find it here.

Shape Memory Alloy (SMA) actuators are great in soft robotics for many reasons, but a major drawback is that their response rate is largely limited by the cooling rate.  For many applications, it makes sense to cool (and heat) SMA’s with water.  However, when a wet SMA actuates, it constricts, and the tube it is […]

My wife and I enjoy playing board games together.  We have an excellent game called Mice and Mystics, which comes with unpainted figurines.  I have a few friends who paint miniatures, and I wanted to try my hand at it.  Below are the results.  

This project has been in the works since August 2015, when the boy scouts I work with asked me to build a Pikachu robot for them.  Between having a baby, research, and lack of funds to buy new parts, I finally have made some progress. Here it is using a 5-button toggle switch I was […]

I have now created a .pdf version of my portfolio.  You can find the high resolution version here.

These images are from my design qualifier exam in 2011.  The design problem was to design a gearbox that connected a Kinect camera to a robot body.  However, the design needed to be child-proof and resist a 3ft drop. My conceptual design included a gearbox and a compliant torque limiter.  The gear train uses a […]
