Lecture Content: Challenge
• Highly mathematical robotics content – sensors, actuators, kinematics, dynamics, control and systems
• Theoretical aspects of design and analysis• Very difficult subject matter to learn and
teach• Requires reinforcement of material to ensure
teaching outcomes are achieved – examples and questions
![Page 5: Teaching Robotics Through Play and Challenge Euan McGookin Department of Aerospace Eng. (formerly Dept of Electronics & Electrical Eng.) University of.](https://reader035.fdocuments.net/reader035/viewer/2022070305/55151419550346a80c8b5ccf/html5/thumbnails/5.jpg)
Lab Content: Play
• Practical implementation of sensor, actuator and programming
• Introduction of mobile robotics• Fast prototyping of mobile robots for a
competition – either robotic gladiatorial games or olympics
• Team based activities to ensure no individual is overworked
• Fun approach to learning practical concepts which provides counter balance for the lectures

Applying the Challenge
• Engagement with lecture activities and reinforcement of subject matter ensured through challenge based approaches to lectures
• These are implemented through three techniques:- Board Work- Direct Questioning- Mid-lecture Breaks
![Page 7: Teaching Robotics Through Play and Challenge Euan McGookin Department of Aerospace Eng. (formerly Dept of Electronics & Electrical Eng.) University of.](https://reader035.fdocuments.net/reader035/viewer/2022070305/55151419550346a80c8b5ccf/html5/thumbnails/7.jpg)
Board Work
• A key part of the robotics course is practical reinforcement of knowledge through problem based session in the lecture
• These examples are undertaken on the board and involve all of the student cohort
• The initial part of the problem is carried out by the lecturer, as an example
• The rest of the problem is solved by volunteers selected from the audience
• All of the cohort are involved by providing advice for the volunteer
![Page 8: Teaching Robotics Through Play and Challenge Euan McGookin Department of Aerospace Eng. (formerly Dept of Electronics & Electrical Eng.) University of.](https://reader035.fdocuments.net/reader035/viewer/2022070305/55151419550346a80c8b5ccf/html5/thumbnails/8.jpg)
Direct Questioning
• Reinforcing taught subject matter is essential for achieving the desired pedagogical outcomes of the lectures
• This is achieved through direct questioning at the beginning and at appropriate points during the lecture
• Selection of student to be questioned is initially voluntary and then random if no volunteer is forthcoming
• This very stressful approach ensures that the students engage with the learning process
![Page 9: Teaching Robotics Through Play and Challenge Euan McGookin Department of Aerospace Eng. (formerly Dept of Electronics & Electrical Eng.) University of.](https://reader035.fdocuments.net/reader035/viewer/2022070305/55151419550346a80c8b5ccf/html5/thumbnails/9.jpg)
Mid-lecture Break
• The third technique is not a challenge aspect but provides compensation for the stress of the other techniques
• This involves a mid-lecture break (of a few minutes) to reinitiate interest in the lecture
• The break can take the form of a discussion about an unrelated topic e.g. a current film review
• Such a break is necessary to make sure that the students feel unthreatened and an informal environment is established within the lecture theatre.

Initiating Play
• The counterpoint to the challenging lectures is the robot construction laboratory sessions
• In order to ensure that the students do not spend too much time constructing their robot designs, LEGO Mindstorm is used
• This is a fast prototyping medium for the design of robotic systems that illustrates some of the practical constraints of robot manufacturing
• Also, the use of LEGO introduces an element of childlike play into the laboratory session that provides an enjoyable release from the lectures

LEGO Robot Construction
• The Lab sessions involve the construction of LEGO Mindstorms based robots for a competition i.e. robot gladiators or olympics
• The teams design, construct and programme their robots so that they are fit for purpose
• The rules for the competition specify the restrictions for the design process
![Page 12: Teaching Robotics Through Play and Challenge Euan McGookin Department of Aerospace Eng. (formerly Dept of Electronics & Electrical Eng.) University of.](https://reader035.fdocuments.net/reader035/viewer/2022070305/55151419550346a80c8b5ccf/html5/thumbnails/12.jpg)
LEGO Robots
• LEGO designs for the Gladiatorial Robot competition

Student Feedback
• Student feedback, from questionnaires and small group discussions, has been positive about this dual approach to teaching robotics
• Most students have participated well in both the lecture and lab sessions
• Attendance and examination results have been very favourable, indicating that the student have engaged well with the learning process
![Page 15: Teaching Robotics Through Play and Challenge Euan McGookin Department of Aerospace Eng. (formerly Dept of Electronics & Electrical Eng.) University of.](https://reader035.fdocuments.net/reader035/viewer/2022070305/55151419550346a80c8b5ccf/html5/thumbnails/15.jpg)
Finding the Balance
• This dual approach has to be handled carefully as a balance is needed between the challenge and play
• Too much challenge will cause the students to be too stressed
• Too much play will distract from the learning outcome of the course
• A light, well humoured approach is needed to ensure success
![Page 16: Teaching Robotics Through Play and Challenge Euan McGookin Department of Aerospace Eng. (formerly Dept of Electronics & Electrical Eng.) University of.](https://reader035.fdocuments.net/reader035/viewer/2022070305/55151419550346a80c8b5ccf/html5/thumbnails/16.jpg)
Conclusions
• A success dual approach has been employed in the teaching of robotics
• Challenge ensures that the students engage with the learning process in lectures
• Play ensures that the students have an enjoyable practical element to the course
• Feedback indicates that this approach provides the necessary learning environment
• A balance is needed between challenge and play for the pedagogical outcomes of the course to be successfully achieved
