Collaborative robots in the classroom deliver hands-on learning

RAMTEC Career center in Ohio is home to the largest, most comprehensive robotics education center in the U.S. In order to increase the number of skilled manufacturing employees to meet future market needs, the school is now training students ranging from middle school to industry professionals with collaborative robots from Universal Robots.

RAMTEC (The Robotics and Advanced Manufacturing Technology Education Collaborative) located in the manufacturing hub of Marion, Ohio, receives input from a large group of industry representatives involved in shaping its curriculum. When local companies started installing a new breed of industrial robots called collaborative robots – or simply cobots – RAMTEC took note. In contrast to traditional industrial robots that stay bolted down inside a safety cage, cobots can work outside enclosures, move between tasks, and operate right alongside humans.

“We did some research and realized that Universal Robots had one of the best collaborative robots on the market. We always want to stay ahead of where manufacturing is going to ensure that when our students leave this facility, they can use the equipment adapted by industry,” says Ritch Ramey, RAMTEC coordinator overseeing robotics training at the nine Tri-Rivers career centers in Ohio. that RAMTEC is the flagship member of. RAMTEC’s goal is to bridge the looming skills gap estimated at 2 million unfilled manufacturing jobs by 2020.

“If we don’t fill that gap, companies are going to move off shore again. In Ohio alone, I think there are 60,000 openings right now that we could help fill by getting high school students and workers retrained, both in the higher-skilled jobs, teaching them to program and operate robots and other machinery while also helping facilitate the entry of more robots taking over repetitive, lower-skilled tasks,” says Ramey.

 

Like peeling an onion

Robotics instructor at RAMTEC, Clay Hammock, says that the Universal Robots are used to teach many different skill sets:

“It’s like peeling an onion; we can bring it down and present it to 5th graders who can start programming within a few minutes. Or take it into a high school setting and have the students do more advanced motion controls. - Or we can teach it in the adult classroom with many of our local manufacturers interested in having their employees up to speed on programming their own UR robots, enabling them to touch up waypoints or maybe rearrange a little bit of the logic on the fly in the production setting,” he says. “It’s really easy to do with the Universal as opposed to some of the other robots on the market right now. “

 

First programming happens in minutes

Kierstyn Graber is a student taking some of her high school credited classes at RAMTEC. After having worked with other industrial robots before the introduction of the UR cobots, she was surprised to discover their ease-of-use.

“Within two minutes we had a basic program running. With the other robots you have to test it, figure it out, put it all on your computer, run out to the robot and monitor it, and then go back and fix it. With UR robots, you hit play on the touch screen right next to it and all the moves happen immediately,” says the student who also enjoys the “free drive mode” that enables user to simply grab the robot arm and “teach” it the desired task by moving it through waypoints added on the touch screen.

 

Safe also means affordable

The UR robots’ built-in safety system enables the robot arm to automatically stop operating if it encounters objects or people in its route. That’s an important aspect in a classroom setting according to Clay Hammock: “The beauty of the UR is that I don’t have to worry about any of my students getting injured when programming a real industrial robot. I can give a quick demo and let them experiment on their own.”

Not having to build expensive safety cages around each robot also means affordability, says Ritch Ramey who sees cobots in the classroom as the future of education in robotics.  “Younger adults working on robots are not always as safety savvy as people out in  industry, but by not having to fence off the robot, we can buy a couple Universal Robots for the price we can buy an industrial robot with a safety cage,” says the robotics coordinator emphasizing the flexibility now also achieved:

“We can move them around the room between tasks as there are so many things a student can do with a Universal Robot that still fits into the industrial robotics model of education that we need.”

 

Students make their own grippers

A common application for industrial robots now taught at RAMTEC is machine tending with a UR robot picking and placing parts in a 3D printer. The printer also came in handy when Mr. Hammock asked the students to make their own gripper for their new cobot. High school senior, Canyon Gamble, jumped to the task: “We went online, I looked up a schematic of the face plate for the UR3 robot and started building from the ground up, figuring out how to attach it and learning exactly how the I/O’s work on the robot,” says Gamble as he excitedly shows “the claw” as he nicknamed his new end-effector.


Using Universal Robots’ free online resources, Canyon Gamble, a high school student at RAMTEC, designed a 3D printed gripper for the UR3 robot.

“I enjoyed it because it was a quick reward kind of process. I would program it in and I could see the effects of my program almost immediately.”

 

Free tech support, simulator and online resources

Experiences like Canyon’s gives the students ownership and has led to a large level of engagement both inside and outside the classroom. The free simulator and other online resources on the UR website are important components in the curriculum that the students can download and use without a required user license.

“The simulator is a very powerful tool in the classroom because everybody learns differently and some of the students want to go through and practice it at home many times. So even if we don’t have enough robots, we always have enough simulators,” says Hammock, adding that the simulator is also used as an assessment tool.

“In this way a lot of the programming actually happens outside the classroom, when we come into the classroom we can then focus on some of the more special things like integrating with Allen Bradley PLC,” says the robotics instructor who also teaches his students to stream commands to the UR cobots from the PLC through Ethernet IP, assigning tasks that involve using the free tech support and online resources on the UR website.

“We can tell the students ‘let’s write a script program and make the robot do something fancy’ and then let them figure it out by going online, practice finding information and downloading the right documents. Just like they may have to in the real world”

Working with the UR robots has inspired Canyon Gamble to pursue a career in factory automation.  “I think it would be cool if I could make a factory line and have one robot do one task and pass it onto the next. I just worked on having two Universal Robots interact with each other, so I could see how they would incorporate that with a factory line,” he explains.
