At the end of the project, the student:
- Is able to read a simple datasheet of electronic components.
- Knows what is the purpose of a Wheatstone bridge, and is able to design the bridge to obtain the best possible sensitivity.
- Knows about sources of errors, and knows the difference between random errors, systematic errors, tolerance, resolution, precision, accuracy, trueness.
- Is able to design, construct a simple measurement system using sensors such as strain gauges, photodiodes, or NTCs and evaluate its performance using the common sources of error.
- Is able to model a basic second-order dynamical system using differential equations.
- Is able to extend the analysis to different physical domains.
- Can design, construct, evaluate and improve a basic mechatronic system.
- Is able to characterize the realized designs with electronic test equipment, apply a systematic approach to fault finding and evaluate the results.
- Is able to make a block diagram of all parts of the system (high level design), to make a physical model of the system, to integrate sensors, to develop hardware, to use the Analog Discovery 2 (or similar device) for data acquisition and to write the software for data processing and presentation (using Matlab).
After the Matlab tutorials are finished, the student (while using Matlab):
- Is able to find his/her way in the Matlab user interface, identifying key elements such as the Command window, Workspace, (live) Editor, Help, etc.
- Is able to conduct numerical and symbolic calculations, matching the topics as treated in the Calculus 1 course.
- Is able to acquire and output digital and/or analog signals using the Analog Discovery 2 (or similar), and visualize these signals in figures with appropriate labels, axis, titles, etc.
- Knows how analog to digital conversion works, and is aware on some of the more basic possible implications on signal quality.
- Is able to write simple programs using (self-made) functions, conditional loops, and is able to design the structure of the program in advance.
At the end of this entire project, the student:
- Knows the importance of team roles in group work, and is able to apply this knowledge to make the team work more effectively.
- Is aware of cultural differences, and how they can affect perceptions in group work.
- Knows how to cite sources from literature properly, and knows that plagiarism and fraud are unacceptable in an academic setting.
- Is able to work on a problem, following the design process as outlined in the HELP manual (identify problem, define requirements, divide problem in functional blocks, etc).
- Knows how to structure a project plan or report, following the guidelines as described in the HELP manual.
- Is able to present a pitch of 4 minutes, with a clear structure (problem definition, and solution), and aware of effective communication (body language, oral skills, etc).
- Is able to receive and provide constructive feedback to peers, under the guidance of a mentor.
- Is able to make a poster with a clear and logical structure, making use of attractive visual elements.
- The student is able to make a time schedule (planning) and task distribution.
In the Sensors and Actuators project students work towards the final goal to develop an integrated electronic Strongman game (in Dutch: Kop van Jut), including actuators to launch a ball, sensors to track the trajectory, and hammer. Sensors and actuators are connected to a data acquisition system (Analog Discovery 2, or similar), while readout and control is provided through Matlab. Essential educational elements of this project are that students are able to use the knowledge provided in the Circuit Analysis 1, and Calculus 1 course and apply it to a mathematical description of a physical 2nd order differential systems in the mechanical domain. In addition the project has a strong focus on acquiring academic skills such as reporting and team work.|
This 5EC project is an integrated part of EE module 1 – ESA, and is organised in Matlab tutorial sessions, pre-projects that focus specifically on sensors, or actuators and differential equations (systems) in the mechanical domain, and the final project to build the Strongman game.
Assumed previous knowledge
|Pre-knowledge: High school diploma – level ‘VWO’, with a profile that contains Math B, and Physics (or equivalent).|
In addition, the course expects that students simultaneously follow (or have completed) the Calculus 1 and Circuit Analysis 1 course.
