There are two types of these "magical" wheels; Freeline Skates and Orbit Wheels. There are a few main differences between them. The Freeline Skates have two small sized skateboard wheels below the foot platform. This eliminates two degrees of freedom, yaw and pitch, which makes them easier to handle for beginners. The flat top foot platform makes Freeline Skates top choice among skaters, because they enable for more complicated tricks. Because Freeline Skates use skateboard wheels, they can be easily swapped; however they are more likely to get caught in a cracks on a sidewalk. On the other hand, the Orbit Wheels have a large hub-less wheel with foot holders on an inside flat edge. The bigger wheels lend for easier travel over cracks, but they also have more degrees of freedom. The choice of which to buy ultimately comes down to the preferences of the customer.
I chose to learn on the Orbit Wheels, because I had recently learned how to ride a unicycle and I liked the idea of having many degrees of freedom to control to remain balanced. After about six hours of dedicated practice over a two-week-long period, I was able to wiggle my way across rooms. I soon found their limitations and starting thinking about how I could improve them. First of all, the Orbit Wheels have a narrow and pointed wheel causing the wheels to dig into soft grass. I wanted to improve on their design by making a thicker and faster wheel. I decided I would build my version of a new Orbit Wheel while at my first semester of MIT.
Upon arriving to MIT, I stumbled around and found the MIT Electronics Research Society. MITERS is a student run shop where tinkerers of all kinds gather and build cool things. Electric vehicles were one of MITERS's many fads at the time. That's where the Electric Orbit Wheels were born, my first real project at MITERS.
For the Epilog Challenge:
What would I do with a Epilog Zing 16 Laser? Well... I would definitely tinker and experiment with it. Maybe try to make 3 -dimensional shapes with acrylic or make book covers out of wood. I'd raster funny images on peanut, butter, and jelly sandwiches, or even on cakes! I would certainly not limit it to a prototyping tool.
