Hello welcome to my new site. It has been revamped for a cleaner
appearance and easier navigation. The site is still under
construction, so I apologize for missing links and incomplete content.
Co-OP 2009-2010
The 2009-2010 Co-Op will build upon my 2008-2009 Co-Op located in South Korea. During that time I gathered much manufacturing knowledge to build Hubo a cutting edge mechatronic humanoid platform. This next co-op will act as a continuation of the already started research. Specifically, this co-op will be split into two parts over the six month period. The first part goal is to replicate a Hubo leg through manufacturing, installation, and implementation on US based platform. During this time I will be professionally trained in MasterCAM and plastics manufacturing. I will also be traveling to Virginia Tech to work through mechanical design/manufacturing of Mini-Hubo. Lastly, I will travel to South Korea for a 1-2 week stay to learn more advanced machining skills. The second half will still be under the umbrella of PIRE, but I will be (possibly) shared with National Instruments (NI) located in Austin Texas. During the remaining three months I will be working with NI Engineers to implement Labview and NI equipment on the Mini-Hubo humanoid.
DASL 141 CNC Manufacturing Class
Each year the summer term is the time when DASL trains potential Undergraduate students to join our lab. This year we offered three courses: CNC Manufacturing, C Programming, and Microcontrollers. I taught a comprehensive course teaching students G codes, AutoCAD Pre-CAM, and MasterCAM. To see more in detail what I taught check out my syllabus. At the end of the term the students need to complete a cap stone project. The students need to manufacture a robot (shown below) that had to use gained programming knowledge and program a microcontroller to make it navigate a maze.
PIRE Mini-hubo
The Mini-Hubo project is part of the Partnership for International Research and Education (PIRE) program granted by the National Science Foundation . A five year project that seeks transformative models to catalyze discovery through international research collaboration, train U.S. students, and create junior researchers to effectively think and work in global teams. DASL worked with Virginia Tech's RoMeLa group to check remote manufacturing feasibility for Mini-Hubo humanoid platform. A successful collaboration took place producing a replica shown below and improvement report.
ATLAS Robogames 2009
Team ATLAS/DASL traveled to San Francisco California on June 12 to compete
at a 3 day international robotics tournament. After six accelerated months
the ATLAS team brought a completed mini Humanoid Robot and took home the Gold
metal in the Autonomous Dash. Check out the re-cap video from our amazing
experience!

^ Work in Process
February 5th 2009
I have just finished the manufacturing the Force Torque sensors that
will be used in the feet of our 2009 Robogames Humanoid. The sensor will use
strain gages to measure deflection of the metal when the robot comes in contact
with the floor. I used a three step process to manufacture this sensor. First I
used CAD to draw the sensor. Then I used CAM to produce the tool paths. The
final step is to CNC the part with a process that articulates a cutting tool in
XYZ space to produce the finished part shown below.

South Korea Co-Op 07-08 Blog
September 5th 2008
I have stared a "blog" with
Blogger.com. This blog will be a portal into the activities that I
experience throughout my stay in
South Korea for Co-Op 07-08 <-Link to personal blog. It will be a mix
of Technology, Social, and Culture. Please check out what I am up to or leave a
comment or two!
Robo-Hoops 2007

Check out
Penn State Abington's autonomous basketball robot competition. Team
PID competition page is up so take a look at the
2007 Robo-Hoops Senior Champions.
DASL Logo Engrave
August 20th 2008
The previous DASL logo engraver was not efficient for making large
quantities. To improve the concept, I overhauled the DASL.jpeg and
re-rendered it in CAD. Then I ran a MasterCAM X2 Contour path generation. I
manufatured
10 key chains to be handed out when Mr. Bossone and Guests visited DASL.
Below is the finished product.
July 24th 2008
Produced the DASL insignia that was engraved into aluminum using a
corner end mill. These will be used for CNC demonstrations and promotional
events. The G code was generated from a freeware program
Image to G-code.
PCNC Mill Mold Project
July 18th 2008
Students from the Hybrid Power Supply Laboratory (HPSL) under the
direction of Dr. Kimberly Cook asked to use our new machine
capabilities. DASL worked with these students to transfer STEP
files to MasterCAM X2 NC code. These were the first machined parts by
our Tormach PCNC to
leave the manufacturing lab of Drexel Autonomous Systems Lab.
