Makerspace Assignments for Existing Courses

At a presentation to our faculty over the summer, we had the opportunity to share some of the awesome ways our makerspace and its tools and equipment can be integrated into a wide range of academic disciplines. Some of what we talked about is on our assignments by subject page.  We were a little worried that all of the new project ideas could be overwhelming, however, especially when many faculty are interested in working with existing courses. In an effort to make things a little easier to digest, we came up with the following:

How to Integrate the Makerspace into your Courses:

  • Look at your courses and think about how a creative assignment or visualization might help in the understanding of a concept, event, place, etc.
  • Think about times during the course when many students had a difficult time understanding or staying engaged with the content and may have benefited from hands-on work or a change of scenery.
  • Do a library database search to find articles about different ways 3D printing & other makerspace tools have been integrated into your discipline.
  • Do a web search to find content about different ways 3D printing & other makerspace tools have been integrated into your discipline.
  • Contact your friendly makerspace coordinators. We have tons of ideas and are happy to chat about them!

It’s even available as an image, if you’d prefer! We know assignment design is a complex process, but we hope these tips can at least make it a little easier for faculty of all academic disciplines to provide high-tech, hands-on coursework for their students.

Wall-Following RC Car

By Wenchao Liu

When I was a junior, I decided that I’d work on autonomous vehicles after graduation. However, as an undergraduate, I’d not be able to produce a research paper in the field.¬†Thus, I dedicated my senior experience to building a self-driving RC car, which was within my reach. Calling it self-driving might be a stretch, since the only capability for the car was wall-following. However, the project really took me a lot of time and energy.

The first step was to build a platform where the electronics could stand. There were a lot of electronics that needed to be on the RC car, and they couldn’t just be taped on the top. Thus, I paid someone to use a laser cutter to cut out different parts of the platform from two pieces of plastics. After assembly, the electronics could safely be placed on top of the RC car. The Makerspace doesn’t have a laser cutter, but Angela purchased one on back order, so we’ll see when we will get it!

The second step was to put the electronics securely on the platform. That process requires a lot of screws, standoffs and even fasteners! In addition, I had to solder a lot of circuits and headers in the Makerspace. There are many useful communal tools in the Makerspace, such as a soldering iron, screw drivers and various types of glue! On top of that, Angela, who is in charge of the Makerspace, is also helpful and wiling to buy almost whatever tools you want! She also has great ears to listen to your complaints when things go south!

The final step was software. I used ROS on Ubuntu to analyze the data from the Lidar, and to send commands from the computer to the micro-controller. The computer uses the Lidar data to estimate the distance between the car and the wall. If the car is too far away from the desired distance, the computer tells the micro-controller to steer closer, and vice versa. How much should the car steer? Well, that is handled by a PID controller, which takes the off-set from the desired distance and outputs the steering angle.

In total, the project took me about half a year. I took a class on Arduino in the chemistry department in the spring term of my junior year (yes, chemistry!) and worked on the project through the following summer and fall. During the entire process, I spent quite some time in the Makerspace, complaining to Angela! When the project was finished, I gave a talk about it, and many people came, including Angela! Look at how much she aged after listening to all my complaints!
