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(maximumtemperature 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 • http://www.robotmarketplace.com/products/battery_build_main.html • http://www.robotmarketplace.com/products/motors_main.html (Motors)
Masses • Robot: • Bottle • Battery • Motors (2) 25 kg • Arm • Frame • Isolation • µC, memory
Mohr Theorems • 1st Mohr Theorem: • 2nd Mohr Theorem:
Beams • Rectangular: • Cylindrical: • I-Beam:
