All flames are extinguished as early as possible, or fire services have to deal with major conflagrations. This leads to the fact that the quality of fire extinguishers has become a very sensitive and important issue in firefighting. Inspired by the development of automatic fire fighting systems, this paper proposes key specifications based on the standard of fire extinguishers that is ISO 7165:2009 and ISO 11601:2008, and feasible solutions to design a mobile manipulator for automatically evaluating the quality or, more specifically, power of fire extinguishers. In addition, a part of the mechanical design is also discussed. Keywords: Portable fire extinguishers, wheeled fire extinguishers, fire test.

All flames are extinguished as early as possible, or fire services have to deal with major conflagrations. This leads to the fact that the quality of fire extinguishers has become a very sensitive and important issue in firefighting. Inspired by the development of automatic fire fighting systems, this paper presents a mobile manipulator to evaluate the power of fire extinguishers, which is designed according to the standard of fire extinguishers named as ISO 7165:2009 and ISO 11601:2008. A detailed discussion on key specifications solutions and mechanical design of the chassis of the mobile manipulator has been presented in Part I: Key Specifications and Conceptual Design. The focus of this part is on the rest of the mechanical design and controller de-sign of the mobile manipulator.


Battery safety and fire handling

Robohub

Lithium battery safety is an important issue as there are more and more reports of fires and explosions. Fires have been reported in everything from cell phones to airplanes to robots. If you don't know why we need to discuss this, or even if you do know, watch this clip or click here. I am not a fire expert. This post is based on things I have heard and some basic research.


Samsung Isn't the Only One with Lithium Ion Battery Problems. Just Ask NASA

WIRED

On June 14, 2016, four researchers at the Jet Propulsion Laboratory were preparing to ship a waist-high, ape-like robot named RoboSimian off-site. They had built the bot to rescue people from dangerous situations that human rescuers can't hack. The scientists swapped one lithium-ion battery for a fresh one, then left for lunch to let the new power supply charge. Left alone in the lab, RoboSimian's battery did what such batteries famously do: went boom. Plumes of smoke vented from the robot's exposed torso, followed by a burst of flame.
