It's the system in which we did our seminal <a href="http://www.research.ibm.com/research/gmr.html">giant magnetoresistance</a>(GMR) work in the late 1990s. GMR was the first of the spin-based technologies by which all data is now read from hard drives. Our car-sized robot layered four magnetic materials on top of one another with atomic precision on substrates smaller than a kitchen match. Today's system is seven times larger than that machine – and it can build those atomically precise layers out of 80-odd different materials in any one experiment.<br style="mso-special-character: line-break;" /><br style="mso-special-character: line-break;" /></span></div><div class="MsoNormal" style="margin-bottom: .0001pt; margin-bottom: 0in;"><table cellpadding="0" cellspacing="0" class="tr-caption-container" style="float: left; margin-right: 1em; text-align: left;"><tbody><tr><td style="text-align: center;"><a href="http://epicfail.xepher.net/wp-content/uploads/2011/04/tiki_dalek.jpg" imageanchor="1" style="clear: left; margin-bottom: 1em; margin-left: auto; margin-right: auto;"><img border="0" height="320" src="http://epicfail.xepher.net/wp-content/uploads/2011/04/tiki_dalek.jpg" width="240" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Kevin Roche (left) with his "Tiki Dalek"</td></tr></tbody></table><span style="font-size: 12.0pt; line-height: 107%;">While I built plenty of models as a kid out of blocks, cardboard boxes and tubes and later Legos – and am not afraid to incorporate electronics into my theater and cabaret costumes and wearable art – my first attempts at hobby robotics only came a few years ago. I was displaying one of my costume creations (the "Tiki Dalek," left) at an event called <a href="http://www.barbot.us/">BarBot</a> in San Francisco in 2011. There were a dozen clever contraptions making drinks with various degrees of success. </span></div><div class="MsoNormal" style="margin-bottom: .0001pt; margin-bottom: 0in;"><br /></div><div class="MsoNormal" style="margin-bottom: .0001pt; margin-bottom: 0in;"><span style="font-size: 12.0pt; line-height: 107%;">About half-way through the evening I looked around the room and realized: <i><span style="mso-bidi-font-weight: bold;">This is like my day job! I could do this!</span></i> Dealing with the fluid components of a cocktail is not far off from the gas-handling automation I have to do in our thin-film deposition systems.</span></div><div class="MsoNormal" style="margin-bottom: .0001pt; margin-bottom: 0in;"><br /></div><div class="MsoNormal" style="margin-bottom: .0001pt; margin-bottom: 0in;"><span style="font-size: 12.0pt; line-height: 107%;">So, I started working on concepts for my bartending robot, ThinBot, and had it ready for the next year's Barbot show.

I quickly realized that with a few more bottles it could make a large assortment of cocktails. It only makes "up" drinks (meant to be served chilled in an up glass, aka a martini glass) because a) that's the sort of cocktail Nick and Nora kept drinking while solving murders, and b) it can only work with non-carbonated liquid ingredients. Note: the Art Deco motifs on the robot are deliberate reference to the milieu of the movies.</span></div><div class="MsoNormal" style="margin-bottom: .0001pt; margin-bottom: 0in;"><br /></div><div class="MsoNormal" style="margin-bottom: .0001pt; margin-bottom: 0in;"><span style="font-size: 12.0pt; line-height: 107%;">The ingredients are loaded into bottles that sit in a tray of flowing chilled water, forming a tower-shaped table fountain with color-changing lighting that splashes softly between drinks. They are precisely dispensed using peristaltic pumps (used because the only thing which touches the ingredients is FDA-approved food-rated tubing), through a 9.5 pound anodized aluminum chilling block, then emerge from jets that swirl all the ingredients into the glass to mix. Because they mix in the glass, you never get contamination from the last person's drinks.<b> </b></span><br /><br /><table cellpadding="0" cellspacing="0" class="tr-caption-container" style="float: left; margin-right: 1em; text-align: left;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiCdg-oR5yc4SmR1aV7CDi1T6tp8bLpWD4oT7rNEcpMrVI1oUR-NWvXFmR6DSYgy6zGGf3IHu7BKPNqyh1ws6gl3XazCZQyprXjJ9T7IobMvspJ_Nr1ZBalYDBIkolZFs3gBd2zZCgz3jLU/s1600/11096394_836461103092888_1869574708221097512_o.jpg" imageanchor="1" style="clear: left; margin-bottom: 1em; margin-left: auto; margin-right: auto;"><img border="0" height="267" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiCdg-oR5yc4SmR1aV7CDi1T6tp8bLpWD4oT7rNEcpMrVI1oUR-NWvXFmR6DSYgy6zGGf3IHu7BKPNqyh1ws6gl3XazCZQyprXjJ9T7IobMvspJ_Nr1ZBalYDBIkolZFs3gBd2zZCgz3jLU/s1600/11096394_836461103092888_1869574708221097512_o.jpg" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Kevin Roche (center) with his ThinBot</td></tr></tbody></table><span style="font-size: 12.0pt; line-height: 107%;">All the control electronics are under a dome in the top of the tower to stay above the liquids, which is capped by a bell. The user places an empty glass on the arm, selects one of (currently 17) drinks from the menu, and ThinBot swings the arm under the nozzle and pours the drink, then swings the arm back out and rings a bell (an actual desk bell) to announce it is served. </span><br /><br /><span style="font-size: 12.0pt; line-height: 107%;">The pouring process itself takes less than a minute; it often takes the user more time to select a cocktail than ThinBot takes to pour it.</span></div><div class="MsoNormal" style="margin-bottom: .0001pt; margin-bottom: 0in;"><br /><b><span style="font-size: 12.0pt; line-height: 107%;">Inspiring work, inspired robots</span></b></div><div class="MsoNormal" style="margin-bottom: .0001pt; margin-bottom: 0in;"><br /></div><div class="MsoNormal" style="margin-bottom: .0001pt; margin-bottom: 0in;"><span style="font-size: 12.0pt; line-height: 107%;">We have a fairly large group here in the lab, and our automated systems are used by many of them. Over the years I've learned a lot about how people react to an interface and expect or want an automated system to behave. I've also learned to aim for design simplicity when possible in the mechanism of a robot because that reduces the possible modes of failure during operation, and makes it more reliable.</span></div><div class="MsoNormal" style="margin-bottom: .0001pt; margin-bottom: 0in;"><br /></div><div class="MsoNormal" style="margin-bottom: .0001pt; margin-bottom: 0in;"><span style="font-size: 12.0pt; line-height: 107%;">When I work on my hobby robotics projects, I've stuck to the relatively primitive controllers. This forces me to write more efficient code and deal with things like memory management. The much more powerful controllers and environments I use in the lab insulate the designer to a large degree from those issues. Coping with the limitations of the small scale will, I hope, translate to developing more efficient code in my work projects.</span></div>
