DIPLOMA PROJECT THEME FOR: Viviana Elena Sînziana DINU 1. Theme title: 3D Printed Robotic Hand Driven by Sensor Glove and Leap Motion 2. Initial design data: The robot hand must imitate the movements of a human hand fit into the glove that has motion sensors. The robot hand will have 5 motors, one for each finger of the hand. The motors will be controlled by a microcontroller. The glove must have 5 motion sensors that read the movement of the human hand that wears the glove, sending the data to microcontroller. 3. Student contribution: - must design the array of sensors that will fit on the glove - implement the sensors data acquisition on the glove - transmit read data to the controller - program the controller in order to interpret…show more content…
What makes 3D printing different from the already in use techniques, namely the subtractive processes in machining traditional manufacturing, which may involve to remove the excess of material by processes like drilling or cutting,[9] is the fact that the desired objects are obtained with no additional post processing manufacturing, but by using additive processes. In this way, each layer is deposited individually, respecting certain coordinates that lead to the wanted shape, described in the digital model. This technology has easily covered a wide area of fields, since the beginning of the current century, with the advance in the construction of the 3D printing machines, such as: industrial design, architecture, automotive, engineering and construction (AEC), dental and medical industries, geographic information systems, civil engineering, jewelry, footwear [9] and so…show more content…
For example, STL files which have been created from 3D scanning model have often this kind of errors. Surfaces that are nor correctly connected or gaps in the models are fine examples of manifold errors. The solution for eliminating these errors are some pieces of software, such as Netfabb, Meshmixer, Cura or Slic3r. (de completat eventual despre ele) The next step is to process the .STL file with software of type “slicer”, which has the purpose to convert the initial model into another file, containing the thin layers that will be successively deposited, of type G-code, that contains the set of instructions designed to specific 3D printers, namely FDM printers. Fused deposition modeling (FDM) represents a technology based on the additive manufacturing processes, like previously described (see Chapter 3.2.1), commonly used for modeling, prototyping and production applications [14]. This is a very frequent technique used for 3D
