Machine-Framing Alternatives If machine framing is too rich for your blood, but you like the idea of assembling framing using tubing and connectors, consider retail display fixture hardware designed for retail stores. Available in plastic, aluminum, or steel, this round or square material can be cut to length, then joined using various connectors. One common style is 1 1/2-inch PVC tubing, available in white, gray, black, and other colors. The tubing connects with various shapes of corner connectors. For example: • A two-way L joins two pieces of pipe at a right angle. • A three-way T joins three pieces of pipe: two pipes connected end to end and a third as a riser. • A four-way T joins four pieces of pipe in an intersection arrangement. . . . and so on. The pipe is made to fit snugly into the connectors. PVC is easy to cut and drill, so you can readily attach other components to the frame. One popular retail store fixture system is Kee Klamp, made by Kee Industrial Products. Yet another idea is to using so-called furniture-grade PVC pipe for small robot frames. This pipe, available in sizes ranging from 3/4 to 2 inches, is intended to make outdoor furniture using PVC pipe and fittings. It is furniture grade because the pipe has been treated with an ultraviolet- resistant chemical (ordinary PVC becomes brittle in time from exposure to ultraviolet). As with retail store fixture materials, you can cut the pipe to length and assemble it using various connectors. Use PVC solvent cement to prevent the pipe from working loose (or you can use self-tapping screws if you want to be able to disassemble the frame in the future). Cut holes in the pipe to mount other components. Use PVC pipe and fittings to make lightweight robot frames. Manufacturer of machine framing.

With nothing more than some pipe and connectors, the scaffold can be built to most any shape and any size—within the lim- its of physics, of course. The scaffold is a kind of large-scale construction toy, not unlike the basic concept of the Erector set, LEGO, Construx, K’NEX, and a long line of similar toys. The difference is simply one of scale. Imagine something in-between toy construction sets and scaffolding. That’s the idea behind machine framing. The system employs lengths of plastic or aluminum rod, con- nected together with various elbows, tees, and hinges. Rather than a simple rounded rod, the material is extruded into unique profiles: hexagonal or square shapes, with flanges and ribs that make it easy to secure other components. With machine framing you can more quickly design the body and other structures of your robots. The framing pieces are cut to length with a hacksaw, then assembled with connectors and other hardware. The typical machine-framing construction does not require drilling, taping, or welding, and this is the main attraction of the system. Everything can be fastened tightly together using the supplied connectors and hardware. Aluminum Leads the Parade The most common form of machine framing is made with aluminum and goes by the more mundane descriptor of alu- minum profile extrusions. Several manufacturers offer alu- minum extrusions, each one with slightly different shapes and connector types (so they aren’t always compatible with one another). Framing profiles comes in a variety of sizes and usually in two “classes”: fractional and metric. The choice depends on what measurement system you’re most comfortable work- ing in. We’ll assume fractional for our discussion, but note that similar products are available in equivalent metric sizes as well. Machine-framing components are first measured by their cross-section dimensions, such as 1 by 1 inch, or 1 1/2 by 2 inch. For most robots, the smaller material is sufficient, and it’s less expensive all around. Sizes of up to 3 by 6 inches are available, when maxi- mum structural strength is required. Literally hundreds of profiles (extrusion shapes) are available, with the “T-slot” the most common. In this profile, a T-shaped slot is extruded on all four sides of a square tube. With the proper hardware, other components can be fastened anywhere along the length of the slot. Components can be moved to another position along the length simply by loosening their fastener, sliding it up or down, and retightening. No drilling! No welding! Frames are constructed using connectors, fasteners, or hinges. Depending on the sys- tem, a square frame can be made using four lengths of profile extrusion and four L- shaped connectors. Hinges offer added flexibility by allowing you to set the angle of the joined pieces. The hinges can be tightened to stay in place. Now, How About Cost? While machine framing offers a fast and efficient way to build the frames and other mechanical systems of medium and large robots, the cost is not cheap. Most extrusions are sold by the foot or the inch. A 6-foot length of 1 by 1 inch T-slot costs on average about $15 to $20.

Nice prices, and the extra lengths of aluminum framing are precut to standard sizes. See also Evolution Robotics: http://www.evolution.com/ x V machine framing 265 home improvement store, is barely half that amount; of course, to use it you must drill mounting holes as needed. Costs can be controlled by carefully selecting the pieces you need, in the exact lengths you need, so there is no waste. A foot of wasted extrusion can cost several dollars, so it’s wise to make your investment stretch as far as it can. Somewhat less expensive is plastic extrusion. This mate- rial is not as strong as aluminum extrusion, and supplemen- tary hardware is not as extensive. However, it costs consid- erably less. Like aluminum extrusions, the common style in plastic is the T-slot, either with a square shape or an octa- gon (eight-sided) profile. Plastic extrusions are cheaper, but not quite as strong. X-Beams packages pre-cut extrusions and connectors. Photo XBeams, Inc. Manufacturer The following sections list manufacturers of products of keen interest to the robot constructionist. These include components, semiconductors, tools, and hobby products. Most manufacturers won’t sell directly to the public. But they are nevertheless good resources for product information, datasheets, and application notes. Plus, a growing number of manufacturers are selling refurbished gear and replacement parts directly from their Web sites. Example replacement parts include motors, gearboxes, and batteries for cordless drills and screwdrivers, or wheels and drive shafts for power gar- den equipment. Scan the company’s parts catalog and you’re sure to find items that can be used on a robot. GManufacturer- Components Manufacturers listed here produce electronic parts that aren’t classified as semiconductors. Most of what you’ll find here are used in robotics for sensors, such as linear and rotary potentiometers for position sensors and LED and infrared components for proximity sensors. Also included here are manufacturers of connectors, wiring harnesses, relays, switches, and other electronics hardware. Most of the manufacturers in this section do not sell directly to individuals, but a few will sell in small quanti- ties via phone orders or the Internet.

There are actually hundreds of makers of various glues, adhesives, and cements, and I’ve listed only a few of them here as representative of what’s available. The obvious use for glues and adhesives (and their close cousin, cements) is to hold robot parts together. But depending on the material, you may also use them to create such things as sensors.

The semiconductor manufacturers listed here run the gamut from large multi-billion-dollar companies with fabrication factories around the world to small specialty designers that “send out” their ICs, transistors, and other parts to be built by someone else. As it turns out, the smaller outfits often have the most interesting specialty products. Look especially for motor controllers, power drivers, switching regulators, DC-DC converters, analog-to-digital converters, solid- state accelerometers and tilt sensors, optical sensors, LCD drivers, and microcontrollers. Most companies listed in this section do not sell directly to individuals. The main benefit of the manufacturers listed here is the product datasheets and application notes you can obtain from them. These are routinely published as PDFs, which require the free Adobe Acrobat Reader program to view (see http://www.adobe.com/ for downloading details). Note that a number of semiconductor makers are only too happy to send out free samples. When sam- ples are available, they are typically for current prod- uct only (no legacy products kept in stock for perpe- tuity), and package styles are limited—for instance, ICs only in surface mount and not in DIP packages. Check the companys’ Web sites for their samples policies.

One particularly useful chip is the ADNS-2051 optical mouse sensor. This chip works by taking thousands of digital pictures each second. It has a resolution of up to 800 counts per inch (CPI) and can track motion of up to 14 inches per second. One possible application is robot odometry over nonfibrous (i.e., not carpeted) surfaces. Specifics regarding this chip can be found at: http://www.agilent.com/view/opticalnavigation/ Note the staggered DIP package design; this is not your standard IC, and it requires special prototyping boards or custom circuit boards. In addition, Agilent offers a number of low- and medium-cost optical linear and rotary encoders for motion control. To round out the line, the company provides various versions of quadrature encoder inter- face and counter ICs, including several that are in a DIP (dual-inline pin) IC package, making them easy to breadboard.
