University of Michigan course SmartSurfaces offers a collaborative, project-based learning experience in which artists, designers, architects and engineers come together to build physical systems and structural surfaces that have the capability to adapt to information and environmental conditions. Max Shtein sets up the topic for the semester. ![]() I. ObjectivesDeposit sand in specified locationsUse only the provided materials and tools Utilize a minimum number of steps / energy transfers Present the design and final mechanism Teams judged on Efficiency, Durability, Economy, Spectacle / Delight of mechanism II. Deposit locationsA given mass of sand starts out at a position 100 centimeters above the table; specified in Cartesian coordinates by (x0, y0, z0) = (0, 0, 100 cm). A fraction of this sand must be deposited in paper cups positioned at 3 locations given by:
III. Materials, ToolsCardboard, String, Duct Tape, Box Cutter, Dowel Rod, Wire, Paper Clips, Binder Clips, Rubber Bands, SandIV. Judging criteriaEfficiency: Delivering a greater fraction of the original mass of sand (from Location 0) to the Location 3 is better than delivering a smaller fraction. Delivering a larger total quantity of sand may or may not be better (feel free to explore this as a design parameter). Delivering equal amounts of sand to all 3 locations might be desirable. (But why?..)Durability: The mechanism you devise must survive the endeavor and must be capable of a repeat performance. The greater the durability, the better. (Or is it?..) Economy: The fewer materials / tools you use to construct the mechanism, the better. Unless you can use more materials, but the overall cost is lower. The exception is when the mechanism could be made much more engaging by using more material. (Unless you think that isn’t as important as when increased capital cost leads to improved efficiency and/or durability...) Spectacle / Delight: Designing and building a more dramatic delivery mechanism is preferred, but not to the detriment of durability. (Unless your whole point was to have an ephemeral / biodegradable mechanism in the first place, or you just wanted to make a “splash” with it. Of course, you might also want to make the least obtrusive mechanism. Or, maybe if you are able to achieve your objectives with minimum amount of material, shortest delivery time, and lowest capital costs, then perhaps the level of “noise” or spectacle doesn’t matter at all...)
