Teaching methodology
The teaching of the subject consists of lectures, exercises and laboratory exercises. The lectures basically introduce students to the information defined by the knowledge competence elements using the technique of frontal education. The slide shows used in the lectures can be downloaded from the online interface of the subject. The practical sessions, in connection with the lectures, basically promote the application and skill-level acquisition of knowledge through two planning tasks. The topics of the laboratory exercises are also related to the lectures, during which the students apply the acquired knowledge in practice.

General rules
The assessment of learning outcomes consists of two mid-year partial performance assessments and a year-end exam. The two partial performance assessments consist of two homework assignments made individually by the students. The exam asks for the knowledge of the lectures. The exam consists of two parts: a compulsory written part and an optional oral part. To obtain a signature and to be eligible for the exam, you must complete the two submitted design assignments, each corresponding to a performance of at least 40%, and complete all laboratory exercises.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | formative assessment, simple | |
| Number: | 1 | |
| Purpose, description: | A complex way of evaluating the knowledge, ability, attitude, and autonomy and responsibility type competence elements of the subject, the form of which is an individually designed design homework; the design task is the mechanical design of a servo drive. With the planning task you can get a minimum of 6 points and a maximum of 15 points, but it is also possible to get extra points. At least 40% completion of the task is required to obtain a signature. The result of the task is included in the result of the exam. The detailed content of the assignment, the requirements, the deadline for submission, and the method of assessment - which will be announced in the first class of the semester - are determined jointly by the person in charge of the subject and the instructors of the subject. | |
| Mid-term assessment No. 2 | ||
| Type: | formative assessment, simple | |
| Number: | 1 | |
| Purpose, description: | A complex way of evaluating the knowledge, ability, attitude, and autonomy and responsibility type competence elements of the subject, the form of which is an individually designed design homework; the design task is to make a system plan for a robotic assembly cell. With the planning task you can get a minimum of 6 points and a maximum of 15 points, but it is also possible to get extra points. At least 40% completion of the task is required to obtain a signature. The result of the task is included in the result of the exam. The detailed content of the assignment, the requirements, the deadline for submission, and the method of assessment - which will be announced in the first class of the semester - are determined jointly by the person in charge of the subject and the instructors of the subject. | |
Detailed description of assessments performed during the examination period
Elements of the exam:
| Written partial exam | ||
| Obligation: | mandatory (partial) exam unit, failing the unit results in fail (1) exam result | |
| Description: | The written part of the exam is mandatory. The written exam measures the level of learning of students determined by knowledge and ability type competencies. The written exam focuses in part on theoretical knowledge and in part on the application skills acquired during the exercises and laboratory exercises. A maximum of 70 points can be obtained in the written exam, and the exam results of students who perform below 40% (28 points) are insufficient. Examiners score 40% or more based on the written dissertation and the design assignments. To determine the recommended exam mark, a minimum of 2x6 = 12 points and a maximum of 2x15 = 30 points can be obtained from the two planning assignments (but it is also possible to earn extra points during the semester) and a minimum of 28 points and a maximum of 70 points can be obtained in the written exam. | |
| Oral partial exam | ||
| Obligation: | (partial) exam unit chosen by the student, the exam result assessed by other partial exam unit can be changed unrestrictedly | |
| Description: | The oral part of the exam is not obligatory, the student can take an oral exam after obtaining the offered grade in the hope of getting a better result. The oral examination may cover both theoretical knowledge and the application skills acquired during the exercises or laboratory exercises. The oral exam can be not only corrective but also degrading. The student is given preparation time for the questions received in the oral exam, during which he / she can also take notes. | |
| Practical partial exam | ||
| Obligation: | does not apply | |
| Description: | ||
| Inclusion of mid-term results | ||
| Obligation: | mandatory (partial) exam unit, but failing the unit does not results in fail (1) exam result | |
| Description: | The exam grade includes the mid-year performance evaluation, ie the result of the two planning tasks. To determine the grade offered after the written exam, a minimum of 2x6 = 12 points and a maximum of 30 points can be obtained from the design assignments, to which is added the score obtained in the written exam (provided that the written exam was successful). As extra points can be earned with the design tasks, their value also increases the score that can be obtained in the exam. | |

| Can the submitted and accepted partial performance assessments be resubmitted until the end of the replacement period in order to achieve better results? | ||
| yes | ||
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| new result overrides previous result | ||
| The way of retaking or improving a partial assessment for the first time: | ||

| Completion of unfinished laboratory exercises: | ||
| missed laboratory practices must be performed in the teaching term at pre-arranged appointment | ||
| Repetition of laboratory exercises that performed incorrectly (eg.: mistake in documentation) | ||
| incorrectly performed laboratory practice (e.g. Incomplete/incorrect report) can be corrected upon improved re-submission | ||
