**This activity gets students to use their knowledge of electromagnetism in order to design and build a magnetic tool holder for a surgical robot. ** Students learn how simple scientific principles can be used in sophisticated applications, how electric circuits can be switched on and off, and the factors that can affect the strength of an electromagnet. Activity introduction Each group is a dedicated design team with a compelling mission – to craft a comprehensive outline design for a tool holder tailored to seamlessly integrate with a surgical robot’s arm. The task at hand: • Each surgical tool boasts a magnetic fitting, necessitating the utilisation of an electromagnet within the tool holder to ensure a secure grip. • A dynamic approach is required considering the diverse range of sizes and weights among these tools; This entails varying the electromagnet’s strength to account for this. Guided by these challenges, teams will brainstorm, innovate, and collaborate to present their inventive solutions in a concise one-minute presentation to the rest of the class and assessed according to the success criteria on the design brief. The engineering context Telemedicine employs contemporary communication technology to provide medical diagnoses and patient care, even when the physician and patient are geographically separate. Remote surgery entails utilising robotic systems within the operating room to aid surgeons during procedures. The surgeon observes the patient through a terminal and controls robotic surgical instruments using a specialised console. Suggested learning outcomes Upon completion of this activity, students will gain an understanding of the capabilities of surgical robots. They will grasp the transformation of basic scientific principles into intricate applications, comprehend the functioning of electric circuits’ activation and deactivation, and discern the variables impacting the strength of an electromagnet.

Students compete to make the strongest electromagnetic tool holder for a surgeons robotic arm. A practical activity where students work in teams to build their own electromagnet and use this to make an ‘arm’ with an electromagnetic gripper at one end. They are given some basic parts to start and a budget - a sum of ‘money’ or tokens with which to buy the other parts. Once their arm and gripper are complete they have 30 seconds to move as many paper clips from one pile to another as possible. The team moving the most paper clips in the allotted time is the winner. This activity makes students consider the factors involved in electromagnet strength and design. Download the activity sheets for free!
