3. 1.What is a haptic device? 2.What does CAD/CAM means? 3.How is made the reading of position using optical encoder in Matlab Simulink? Haptic device with Arduino

4. Answers 1. The origin of the word haptics is the Greek haptikos, meaning able to grasp or perceive. Haptic sensations are created in consumer devices by actuators, or motors, which create a vibration. Those vibrations are managed and controlled by embedded software, and integrated into device user interfaces and applications via the embedded control software APIs.

5. 2. Computer-aided technologies (CAx)[1] is a broad term that means the use of computer technology to aid in the design, analysis, and manufacture of products. Advanced CAx tools merge many different aspects of the product lifecycle management (PLM), including design, finite element analysis (FEA), manufacturing, production planning, product.

6. 3. One can use the Matlab Data Acquisition Toolbox, if you have access to that.Data Acquisition Toolbox Alternately, a digital storage oscilloscope may be about to capture data in some kind of spreadsheet format that you could easily import into Matlab. It’s needed to set the sampling rate high enough to avoid aliasing. For a conventional rotary encoder, that the critical time is about 0.5 ms, so you need to sample at 0.25 ms or less (4000 Hz). You'll need to ensure your data capture system is properly configured to capture these events. For your optical encoder, the sample time will be related to the maximum speed you are trying to capture and the number of positions in the encoder.high enoughaliasing
