By Vinh-Khoa Ton, Control and Image Processing The purpose of this ultrasonic sensor examination was to determine the range and angle of the sensor detection. The ultrasonic sensor will be used as the eyes of ROFI and ROFIA for the purpose of avoiding obstacles. The Seeed Studio Ultrasonic Ranger v1.0 was the device chosen for this examination. […]
By Juan Montano Hello, this study will try to determine the number of fans that would be required for the UFO. The number of fans used in the UFO must meet the criteria of achieving lift off at 50% +/- ∆. First, we determined the weight of each component currently provided to us by the […]
By Jake Rice UFO Abducted must be able to fly around a classroom using ducted fans driven by brushless DC motors. To achieve untethered flight, a battery must be used to power the motors. In selecting a battery for the UFO, the three main considerations are weight, maximum discharge current, and energy capacity. A lithium-polymer […]
By Maxwell Nguyen In order to eliminate the need for larger servos, the rover team will be implementing mirrors to provide vision for the rover. As compared to lifting a phone, the torque and power require to lift a mirror is substantially less. Objective: The objective of this study is to examine whether a mirror […]
By Gregorio Rios – 3D Modeling 3D printed objects, whether they are ABS or PLA plastic will require a method to smooth out the surface. There will always be visible lines on the surface of the printing objects. These lines on the surface are from the layers of plastic being printed one on top of […]
By Mason Nguyen, Project Manager Solid Works simulation by Vinh Kim Solid works model: In order to build a durable and low budget hexapod, resin molding would the primary component for our team to use. The robot is developed based on a previous version which is focused on the straight-line walking. To enhance its ability […]
By Anh Nguyen ADVANTAGES: Simple to build. There are a lot of information, manual and video to help building. http://reprap.org/wiki/Mendel_Build_Manual http://www.youtube.com/watch?v=mpOZ1GNZmmU Big print area, smaller machine footprint Light and portable The price is reasonable and within budget. DISADVANTAGES: The frame and the joint junctions are not stable in the x-axis. The head […]
By Mevan Fernando Mendel90 Build Manual: http://reprap.org/wiki/Mendel90_Build_Manual#Getting_Your_Parts More info: https://github.com/nophead/Mendel90 http://reprap.org/wiki/Mendel90_Buyers_Guide http://www.thingiverse.com/tag:mendel90 Advantages Designed by Nophead (Good parts/service available from Nophead, very detailed, high quality instruction manual, shared his design through his blog: http://hydraraptor.blogspot.com/2011/12/mendel90.html ) Sturdy structure means faster speeds in the x and y directions Easy to assemble Not a lot of calibration is […]
By Omair Tariq (Information on the Laur3K can be found here) Advantages: A lot of documentation (Pictures, Videos Parts list) Without belts Skechups of parts for printer also available Disadvantages: Print beds moves in y and z directions Uses a lot of 3d printed pieces Costs about $700. (Without printed parts, wiring, and controller)
By Omair Tariq, Systems and Test Engineer How bioprinting works: In order for cells to survive and grow, they need a certain environment. This environment is provided in gel scaffolds, referred to as biopaper in laymen’s term. There are several ways of 3D bioprinting. One of these ways is to print a layer of gel […]
