I taught a class called Reinventing the Wheel at ITP. The class will dive deep into one of the simplest machines. The humble wheel has been with us for millennium, but is ripe for reinvention. We will investigate and create wheeled mechanisms, toys, kinetic sculptures, and robots. Our objects will roll, spin, and slide. We will cover fabrication, mechatronics, design, and engineering techniques. This class will be prototype and fabrication heavy with multiple projects and a final.
Some interesting prototypes came out of my research and preparations for the class.
Making Wooden Wheels With a Drill Press
Using just two drill bits and a drill press, you can make simple wooden wheels.
Pretty beefy wheels and axles for some toy cars. Everything to make these are off the shelf.
18-8 Stainless Steel Female Threaded Round Standoffs - 1/4" OD 5/8" Lg. 10-32
Tight-Tolerance Shoulder Screws - 1/4" Shoulder Dia. - Head Dia.: 3/8", Head Ht: 3/16"
High-Temperature Silicone O-Ring - 3/16 Fractional Width, Dash Number 322
Prime-Line Products D 1503 Steel Ball Bearing Sliding Door Roller, 1-1/2-Inch, 2-Pack
Two axels sharing the same axis, allowing for two wheels to spin at different speeds or directions on the same axis.
CNCd Laminated Plywood Wheels
Repeated CNC'd plywood shape, glued in alternating layers, and turned on the lathe.
Each cam can be individually positioned, or programmed, on the axel.
The idea is to have a wheel that can roll like a ball when collapsed, and move like a roller when expanded.
Velcro Friction Wheels
Using velcro between friction wheels, allows for more "slop" in your functioning mechanism.
Milled sheet aluminum, with bent fins.
