Machine Controlled By ArduinoAbstractThis paper presents an Arduino-controlled Spirographtm-style drawing machine suitable for useat a Maker event. Visitors can use the machine to make unique artwork to take home.Instructions to build the drawing machine are provided. Potential pedagogical uses of thedrawing machine range from learning hands-on construction techniques, to programming,trigonometry, and interaction with a user through sensors.OverviewThis paper provides instructions on how to build a pantograph drawing machine using anArduino UNO microcontroller, a reflectance sensor, two rc-servo motors, and a sheet of foamcore poster board. It is based on the work of Erik Brunvand, Ginger Alford, and Paul Stout [1,2]and extended by using a
, whichbounces off a reflective surface and returns to the sensor. Then, using the amount of time it takesfor the wave to return to the sensor, the distance to the object can be computed.The ultrasonic range finder emits a high-frequency sound wave that alerts the robot to things inits path. A Programming Kit is needed to change the program in the VEX Controller. These arespecific behaviors achieved by the ultrasonic range finder: measure distances from 1.5in to115in; detect obstacles using high frequency sound waves; create more autonomous functions.The sensor can be used to determine distances to objects. It can be used as a tool to determine ifany objects are in the robot’s path at all. To increase the sensing range, the sensor can bemounted to a

This means that either object can be rescaled,repositioned, and reflected, so as to coincide precisely with the other object. Figure 1.

participants to learnabout this concept, our research team has developed a game that allows participants to build theirown model of an engineer complete with engineering habit of mind, personal interest andmotivation. This paper seeks to explain how this game was developed and intended to be played.Development of the GamePieces of the engineering body were sketched on a 2D sketching software, and printed using alaser printer and cardboard. The head, for example had the basic shape of a circle and wasiterated to form an oval, a quarter circle and a semi-circle. Arms were developed from the basicshape of a rectangle, triangles for the torso (body) pieces and hexagonal piece for the legs. Eachpiece was intended to reflect a gender neutral engineer that

Piezoelectricity and the Piezoelectric effect today are crucial concepts that have usefulapplications in: the production and detection of sound such as electric pickups, and microphones,nanotechnology, linear motors and rotational motors used in precision optics, electric ignitionssuch as used in cigarette lighters and barbecue grills.

corresponds to four credit hours. The year is structured into twelve milestones withspecific deliverables from the team due at each milestone. The course milestones are: (1)project exploration, (2) team formation, (3) problem identification, (4) conceptual projectrepresentation, (5) technical and logistic representations, (6) second iteration and reflection, (7)fabrication and unit test, (8) system integration and test, (9) finalize representations, (10) systemacceptance test, (11) client delivery, and (12) final reporting and reflection.The rationale for creating a much more structured design course was the observation thatstudents were often not sufficient familiar with the design process to exhibit good design habits.While students were exposed to

A domestic service robot canfulfill these demands easily. Therefore, home monitoring and surveillance is a good example ofthe basic applications that robots can easily do for us, and it can serve as the first step for thosewho are willing to learn mobile robotics from the scratch to finished products.In this RET project unit, students will learn how to build the robot which can patrol and monitorour house condition when we are away from home. The challenge of this research project is two-fold. First, the robot must be able to move freely and patrol the area autonomously. Second, it mustbe

The authors intend to continue using this assessment tool to track studentprogression towards GD&T mastery throughout the curriculum. The data can serve as anindicator of the effects of any system changes (instructor, course activity, prerequisite orsequence, etc.) as well as monitor general improvement or decline in performance.Of course, exam questions are not the only way to assess the effectiveness of the new integratedeffort. Some of the inspiration for the effort began in the job offerings, job descriptions, and jobinterviews that students and instructors have been seeing more of

For example, the stars were placed in the Ursa Major(Big Dipper) constellation that would be recognizable to the festival attendees. Audiencemembers were encouraged to name the constellations, and to arrange their stars in other patterns.The material colours were chosen to reflect the ranges found in star formations as they age,providing the attendees with additional information about astronomy.The operation of the stars was that of a simple circuit containing the four basic circuitcomponents: a power source, wires, a load, and a switch.

that allow students to understand realscenarios, or creating scenarios for practitioners to reflect upon their required application is very complicated;however using Lego based physical simulations increase the effectiveness 6. Creating these simulations allowsthe concepts of Lean to be thought in a “game” based scenario called Gamification7. The concept ofGamification is applied in order to use a set of games in a series of contexts to transmit knowledge moreeffectively to any type of audience, from kids to technical experts in specific areas. Here, the authors explore on the comparison of teaching effectiveness in Lean principles using physicalhands-on simulation and computer based simulation. Both the techniques used are based on Lean
. Parametric solid modelling and surface modelling are the basic CAD technologies. Solid modelling creates a model that has the filled volume. It closely represents a physical object by having data of physical properties such as mass, density, along with the geometric information. Surface modelling, on the other hand, generates the outlook of the objects as a surface model but doesn’t reflect the physical properties as in a solid model. Solid modelling is preferred over surface modelling in AM as it has simpler representation of geometric information and provides information that is useful to generate tool path. 4. 3D scanning technology enables reverse engineering of a physical part

Data defines interaction between devices and produces predictiveenvironment for the next steps of the process. Thus system holds information aboutphysical devices and provides decision making support, analytics and prediction.

TheMakerSpace programs and related technologies such as 3D printing and prototype makingencourage curiosity for learning and creating new things and sharing of work and processes withothers in the community of students, teachers, staff, and local residents1.

Use of these catalogsconstrained students to the tooling available to them, and served as a more effective way ofconveying the tooling capabilities of the lab. Rather than searching for a tool in the lab, a studentis able to simply view the appropriate tool catalog in NX and CATIA, and determine if the tool isavailable. This is not to say that specialty tools cannot be used within the workflow. Rather, it issolely a means to convey the standard tooling capabilities.The real power of the workflow lies in the creation of a process catalog. A process catalog is thekey element that

Comfort zoneis personal; the activities will help the student break out of that comfort zone throughself-pacing and guidance directed at his learning style or skill level. Failure isencouraged; unlike the traditional exam-based schooling methodology that penalizesmistakes, in Maker culture failure is not only expected, it is fostered and encouraged,given that through mistakes, failure and perseverance, students are able to prototype,practice and master the acquired skills.

The tasks required of the EET group overall were reflective of the necessary skills of both phases of the project. In this case it involved going through a selection process to properly choose and implement an electrical system in a 3-D printer that was comparable to a printer currently in the ET building of IUPUI. Secondarily our managerial responsibilities became more stringent in the second phase of the project because there was a new group of MET students inheriting the project, as the MET degree only
