Assistive Devices

Societal changes ask for (prolongued) self-reliance of people, both for their functioning in a working environment, as well as at home. Furthermore, nowadays employers are responsible for sustainable employment of their employees. Assistive devices can support and train people in their tasks in order to increase their self-reliance and their employment. Examples of such devices are exoskeletons but also (haptic) training devices.

The minor focusses not only on developing an assistive device, but also on evaluating its functionality and performance.

More specifically, you will learn to:

1. Analyse a situation of the target group for which the device will be developed and translate this into requirements and specifications for the device

2. Analyse dynamics of human movements through simulation

3. Distinguish between different control methods, such as haptic control methods, and their specifications and choosing the most suitable one for the human-device combination

4. Select the appropriate sensor and actuator system for the assistive device

5. Develop a concept and detail design of an assistive device

6. Being able to minimize the mass of the assistive device

7. Design a user friendly interface, taking into account the activities and possible disabilities of the person

8. Develop and test the functioning and performance of the assistive device

9. Implement the controller and tune it to obtain the desired response

10. Setting up a research plan and using it to systematically evaluate the use and performance of the device

Summary of contents:

The minor consists of 6 courses and a project with a company as one of the stakeholders.

Courses and project with learning goals:

1. Biomechanics, learning goals 2 (in period 3)

2. Control methods, learning goal 3 (in period 3)

3. Sensor and actuator systems, learning goals 4 (in period 3)

4. Construction and FEM, learning goal 6 (in period 4)

5. Human machine interaction, learning goal 7 (in period 4)

6. Research and test methods, learning goal 10 (in period 4)

7. Project, learning goals 1,5,8,9,10 (in period 3 and 4)

Leerdoelen

The focus of this minor is to introduce students into the field of assistive devices. Students learn technologies applied in this field and learn to evaluate the added value of the assistive device to society, such as described by the learning goals in the section "General objectives".

Furthermore, after following the minor, you are able to:

• Analyse a situation of the target group for which the device will be developed and translate this into requirements and specifications for the device

• Explain and apply techniques for modelling and design of assistive devices

• Realise an assistive device by implementing the learned techniques in the courses

• Develop a structured approach in testing and evaluating the functioning and performance of the device

• Documenting both the design considerations, as well as the final result in a structured manner

Aanvullende informatie

Target group:

Third and fourth year Bachelor of Engineering (BEng/BE) students with, for example, a background in mechatronics, human kinetic technology, engineering physics, mechanical engineering, industrial product design, civil engineering.

Festo

Minimum and maximum participation:

Minimum of 10 students

Maximum of 35 students

Contact hours:

The minimal number of guided contact hours (lectures and project guidance) per week is: 6 hours (these are clock hours).

Miscellaneous:

The courses, project and all documents and reports will be in English language. The members of the project groups will have different nationalities, which will prepare students to work in an international environment.

The validation of the assistive device gives students a thorough understanding of applied research.

Ingangseisen

To start with this minor you should have mastered the following subjects:

• Matrix calculus: matrix vector multiplication, solving set of linear equations;

• Dynamics: speed, acceleration, free body diagrams and equation of motion;

• Basics of control engineering: transfer functions, block schemes, system responses;

• Introduction in programming: some experience with writing of programs in a compiler or interpreter language, such as C, C++, Python or Matlab;

• Construction: analyzing of forces and stresses on and within a construction

• Project management: experience with working in project groups, writing a plan of approach, parallel planning, goal oriented working.

In addition, you should have completed the propaedeutic exam and obtained at least 60 ECTS of the main phase (hoofdfase) of your study.

Toetsing

The assessment of the minor consists of the assessment of the different courses and the two assessments of the project.

 

The project assessment is done at the end of period 3 and at the end of period 4 (in week 9, resit in week 10):

  • assessment part 1 (end of period 3) (corresponding to 6 ECTS)
  • assessment part 2 (end of period 4) (corresponding to 6 ECTS)

 

The examinations are held in period 3 (week 8, resit week 10):

  • Biomechanics (study load corresponds to 3 ECTS)
    • written exam
    • practical assessment (V/O)
  • Sensor and actuator systems (study load corresponds to 3 ECTS)
  • written exam
  • practical assessment (V/O)
  • Control methods (study load corresponds to 3 ECTS)
  • written exam
  • practical assessment (V/O)

 

The examinations are held in period 4 (week 8, resit week 10):

  • Construction and FEM (study load corresponds to 3 ECTS)
  • Portfolio
  • Human machine interaction (study load corresponds to 3 ECTS)
  • Portfolio
  • Research and test methods (study load corresponds to 3 ECTS)
  • Portfolio

The final mark is given only when the individual assessments are all at least 5.5 out of 10 and is calculated as a weighted average of the assessments where the weights are given by the number of ECTS.
