NASA uses mobile fab shop to showcase welding, fabrication to students
Armstrong Flight Research Center team repairs student robots with mobile lab

NASA is much more than astronauts, pilots, and engineers.
Welders, mechanics, information technology specialists, and others keep the space agency operational—it's just that you may not hear much about them.
A new addition to NASA’s Armstrong Flight Research Center at Edwards Air Force Base in California has made some of these workers and jobs much more visible. In February the research center obtained a fabrication shop on wheels as part of its involvement in the Robotics Alliance Project (RAP), a NASA initiative aimed at increasing youth interest in science, technology, engineering, and mathematics (STEM).
The 36-ft.-long trailer includes an arsenal of onboard equipment that includes a mill, lathe, drill press, metal saw, metalworking tools, and welding equipment.
The mobile shop made its debut at three FIRST Robotics Competition events in California earlier this year. A group of Armstrong employees and one volunteer manned the shop, taking and fulfilling work-order requests submitted by students involved in the robotics competitions.
Officials said the goal is to have these mobile shops on hand at all 10 NASA centers. The shops also may be used to aid in emergency response efforts someday.
Jason Nelson, lead engineering technician, and David Voracek, chief technologist at NASA Armstrong Flight Research Center and project manager for RAP, spoke with The WELDER to discuss the mobile shop, what they assisted students with, and how they generated student interest in areas like welding.
TW: What can you tell me about the equipment inside the mobile fabrication shop?
JN: The new trailers—specifically ours—come with a 13-in. by 30-in. South Bend lathe, a Wells-Index (milling machine), refurbished full-size mill, advanced saw, a mill/drill combo, a cold-cut saw, and a 400-amp Miller welding machine with TIG and stick capabilities. We use the TIG primarily because 90% of these robots are made of aluminum.
We can do welding repairs for them on-site. The trailer also comes with its own generator if we needed to go fully mobile.
TW: What is the process for a student to have their robot repaired?
JN: Sometimes students are not aware [of the process]. They'll come out to the trailer thinking they can just run in and use some of the tooling. We can’t allow that for liability reasons.
We do have a mock paperwork order that we ask them to fill out with notes on what needs to be done. We even have a little grid on there so they can sketch out the part that they need, if they need exact dimensions made, things of that nature.
We just try to get work orders done as soon as possible for them. And that’s more so they can get used to processes once they get out of high school and into the real world. And it also helps us keep track of what we actually do.
TW: What type of work orders have you received from students?
JN: I’ve seen anything from “Hey we need to cut this shorter,” to “We need a tab,” “We broke this,” “Can you straighten this,” “Can you tap this rod for us,” “Can you weld some brackets for us,” or “Can you re-weld our robot, it cracked here.” We’ll even do some soldering.
We try to get the work orders in and out in no more than five minutes. Some of them, like welding, could take a little longer.
TW: How many orders did you receive at the Monterey, Fresno, and Lancaster, Calif.-based robotics competitions?
JN: In Monterey we processed about 60 work orders in the three days we were there. It varies from day to day. The first day—their practice day— is the heavy day and it kind of dwindles from there.
And then in Fresno I printed out 75 work orders and ran out of [the paperwork]. We did at least 80 jobs in Fresno.
TW: Was it encouraging to witness the curiosity and interest coming from students at these competitions?
JN: To be honest, 30% of the kids are more interested in the engineering side of things. About one-third of them are more interested in the vocational side, the milling and lathing and welding aspect of it.
You do have some kids that are the manufacturers or the fabricators on their teams. Some schools are lucky enough to have shops that have a lathe or a mill or saws that they can use. But then again, it seems to be the majority of machinery in schools is very old. So, when they see ours, they get wide-eyed.
We talk to students about further education and what they’re interested in. We'll talk to vocational students about junior colleges that have the welding and machining programs. Same with the engineering students—we’ll talk to them about internships, further education, and the importance of interacting with manufacturers and fabrication shops to create the correct part they are trying to design and engineer, with the understanding that it’s a team effort amongst everyone.
Programs like this allow the kids to have that tool aspect where they can do some engineering and fabricating at the same time.
TW: A lot of people think NASA is comprised solely of engineers, astronauts, and scientists. Are there opportunities for careers at NASA in manufacturing and fabricating?
DV: I’ve been an engineer for 35 years. I’m not much of an engineer if I can’t build the things we want to make. There are so many people, like welders, that [bring life to the ideas.]
A lot of us come up with ideas, but those ideas are always improved upon when we send them to the welders and the other techs.
