MagPerch - Crazyflie Magnetic Perching


Welcome to our final project for Robotics Systems Integration at Olin College. We modified the low-cost CrazyFlie drone platform to be able to attach itself to vertical magnetic surfaces. magnetic perching capabilities.

Project Objective

  • Initial Goal: Use a model-predictive-controller to achieve autonomous perching and de-perching with an onboard electromagnet
  • Re-scoped Goal: Use a model-predictive-controller to execute a perching trajectory and attach to a magnetic surface using permanent magnets.

Ethical Impacts and Responsible Use

Ethical Impacts and Responsible Use Statement:

Our magnetic drone perching system presents promising benefits in various fields, such as infrastructure inspection, surveillance, and environmental monitoring. The potential advantages include increased operational efficiency, reduced environmental impact through energy conservation, and enhanced safety in challenging conditions. However, we recognize the importance of critically assessing the system's deployment to mitigate potential consequences.

Benefits:

Efficiency: Our system aims to improve the efficiency of search-and-rescue drone operations, reducing mission down time and resource consumption.

Safety: Perching can allow autonomous docking and charging, reducing the risk of a operator injury. 

Potential Consequences of Misuse:

Privacy Concerns: Perching can be used to enable surveillance which raise concerns about privacy infringements.

Environmental Impact: If perching fails in an environment not accessible by an operator, you have essentially littered a lithium-polymer battery and several circuit boards with toxic components. 

Guidelines for Responsible Use:

Privacy Protection: Ensure that the deployment of the magnetic perching system adheres to all local and federal privacy regulations and guidelines, obtaining necessary permissions and to communicate to residents who may be in an area of deployment.

Security Measures: Implement robust security protocols to prevent unauthorized access and potential misuse of the perching system, safeguarding against potential risks.

Environmental Considerations: Never deploy this system in an area outside of operator accessibility.

Continuous Evaluation: Regularly assess the system's impact on the above categories, seeking feedback from users and rapidly addressing their concerns.

By adhering to these guidelines, we aim to ensure the responsible and ethical use of our magnetic drone perching system, fostering positive contributions to society while minimizing potential negative consequences.
