pteromys: interactive design and optimization of free-formed free-flight model airplanes
Bookmarked 594 weeks ago siggraph 2014http:www-uiissu-tokyoacjpumegliderdesign2014_siggraph_gliderdesignhtmlnobuyuki umetani yuki koyama ryan schmidt and takeo igarashi this paper introduces novel interactive techniques for designing original hand-launched free-flight glider airplanes which can actually fly the aerodynamic properties of a glider aircraft depend on their shape imposing significant design constraints we present a compact and efficient representation of glider aerodynamics that can be fit to real-world conditions using a data-driven method to do so we acquire a sample set of glider flight trajectories using a video camera and the system learns a nonlinear relationship between forces on the wing and wing shape our acquisition system is much simpler to construct than a wind tunnel but using it we can efficiently discover a wing model for simple gliding aircraft our resulting model can handle general free-form wing shapes and yet agrees sufficiently well with the acquired airplane flight trajectories based on this compact aerodynamics model we present a design tool in which the wing configuration created by a user is interactively optimized to maximize flight-ability to demonstrate the effectiveness of our tool for glider design by novice users we compare it with a traditional design workflow |

a hybrid hydrostatic transmission and human safe haptic telepresence robot
Bookmarked 502 weeks ago we present a new type of hydrostatic transmission that uses a hybrid air-water configuration analogous to n1 cable-tendon transmissions using n hydraulic lines and 1 pneumatic line for a system with n degrees of freedom dofs the common air-filled line preloads all dofs in the system allowing bidirectional operation of every joint this configuration achieves the high stiffness of a water-filled transmission with half the number of bulky hydraulic lines we implemented this transmission using pairs of rolling-diaphragm cylinders to form rotary hydraulic actuators with a new design achieving a 600-percent increase in specific work density per cycle these actuators were used to build a humanoid robot with two 4-dof arms connected via the hydrostatic transmission to an identical master stereo cameras mounted on a 2-dof servo-controlled neck stream live video to the operators head-mounted display which in turn sends the real-time attitude of the operators head to the neck servos in the robot the |

mri-powered self-assembled gauss gun for tissue penetration
Bookmarked 548 weeks ago video component of icra 2015 paper quottoward tissue penetration by mri-powered millirobots using a self-assembled gauss gunquotabstract mri-based navigation and propulsion of millirobots is a new and promising approach for minimally invasive therapies the strong central field inside the scanner however precludes torque-based control consequently prior propulsion techniques have been limited to gradient-based pulling through fluid-filled body lumens this paper introduces a technique for generating large impulsive forces that can be used to penetrate tissue the approach is based on navigating multiple robots to a desired location and using self-assembly to trigger the conversion of magnetic potential energy into sufficient kinetic energy to achieve penetration the approach is illustrated through analytical modeling and experiments in a clinical mri scanner authors aaron t becker ece university of houston ouajdi felfoul pierre e dupont boston children039s hospital and harvard medical schoolinteractive tool for optimizing a gauss gun: http:demonstrationswolframcomoptimizingagaussgunvideo of our toy gauss gun shattering light bulbs: https:youtubenwytd7df0yspaper nominated for quotbest medical robotics paper awardquot and quotbest conference paper awardquothttp:icra2015orgconferenceawards |

a layered fabric 3d printer for soft interactive objects
Bookmarked 558 weeks ago link to publication page: http:wwwdisneyresearchcompublicationa-layered-fabric-3d-printer-for-soft-interactive-objectswe present a new type of 3d printer that can form precise but soft and deformable 3d objects from layers of off-the-shelf fabric our printer employs an approach where a sheet of fabric forms each player of a 3d object the printer cuts this sheet along the 2d contour of the layer using a laser cutter and then bonds it to previously printed layers using a heat sensitive adhesive surrounding fabric in each layer is temporarily retained to provide a removable support structure for layers printed above it this process is repeated to build up a 3d object layer by layer our printer is capable of automatically feeding two separate fabric types into a single print this allows specially cut layers of conductive fabric to be embedded in our soft prints using this capability we demonstrate 3d models with touch sensing capability built into a soft print in one complete printing process and a simple led display making use of a conductive fabric coil for wireless power reception |
