Safety issues

• Safety for:– People– Robot – Environment

People

• People

– They are at first place(laws of Asimov)– Don't collide with people– Don't injure people with extinguisher

• Don't use toxic extinguisher– Problem with high concentration CO2

(breath, product inside at -76ºC)

→ better to use water extinguisher» Fire class A

Robot

• Different heights in the cinema• Avoid obstacles

– Seats, floor, technic, ...

(it can block, break robot)

• Safety mounting of robot's parts (nothing can fall down)

• Thermal isolation of electric devices

Robot

• Batteries– We need long lifetime– Problematic plastic parts(maximum

temperature is only 80 C)– working temperature of batteries

• from -40 to +70 C• Similar to electric devices

• Maintenance

Notes:

• Extinguisher – working temperature -20 -+60C

• BATTERIES – POSSIBLE TO DESIGN YOUR OWN PACK – count of cells → voltage, capacity
