What is major difference between the electric and mechanical brakes incorporated in the robot? I

I am a researcher incorporating UR5 robot for image guided surgery. For overall analysis of the robotic arm I am suppose to prepare a thorough documentation so need to address this question. Please help me.

Hi,
In fact, the electrical brakes are used by the robot to control his acceleration and deceleration between 2 waypoints (When the robot move). The mechanical brakes are mostly used for the safety side (ex: when the e-stop is pushed) or when the robot is not electrically powered. It's really not recommended to stop a robot using the mechanical brakes because it does a really hard stop. I suggest you to do a risk assessment before go ahead with your project. Collaborative robots are not frequently used for surgery.

I need to validate this information with Universals robots. But for right now i don't think so because an emergency stop is use and required in safety controls. The robot need to be and stay in safe mode without any source of power.

Hi Mr. Philippe,

Thanks for your answer. I want to know Is there a way to activate electrical breaks by emergency stop?
