What type of materials should be avoided for safety reasons in robot design?

In the context of robot design for safety, it is crucial to avoid hazardous materials and sharp edges. Using hazardous materials can pose risks including toxicity, fire hazards, and environmental harm. Sharp edges can lead to injuries for team members, spectators, or anyone interacting with the robot. Safety is a primary concern in robotics, especially in competitive environments where robots can be in close proximity to people.

The emphasis on avoiding both hazardous materials and sharp edges is aimed at ensuring a safe working environment while minimizing the risk of accidents during the design, build, and competition phases. Thus, it is imperative for teams to consider both the materials they are using and the design of those materials to enhance safety for all involved.
