  1. Bots IQ Safety Review March 18, 2008

  2. Bots IQ Safety Review • School Safety • Tournament Safety

  3. School Safety • Electrical • Pneumatic • Metalworking • Robotic

  4. School Safety vs. Industry • OSHA enforces safety requirements for industry • L&I enforces safety requirements for schools

  5. Electrical Safety • Double insulated tools • Lockout/tagout procedures

  6. Pneumatic Safety • Compressed air limit (cleaning)- 30 psi • Vents on gun can not be blocked • Cylinders need to be secured

  7. Metalworking Safety • Special areas- Welding, Abrasives, etc. • Wear the proper PPE- glasses, shoes, plugs, gloves • Use machine guards, bystander protection • Fire prevention- watch, extinguisher, etc. • Lubricants and fluids- skin, disposal, etc. • Material handling- proper lifting techniques, clamping devices

  8. Robotic Safety • Interlock safety device- E stop • Audible or visible warning system (power on) • Sharp, pinch, or nip points physically guarded • Restraint on moving components • Confined or isolated area for testing • Conduct training of staff • Security/Tampering of Bot

  9. Tournament Safety

  10. Team Requirements • Minimum 4 people • 3 students • 1 adult • No maximum on students but only 2 adults supervisors allowed • 2 adult Technical Advisors are also allowed • Adults can help fabricate but NOTHING else

  11. General Rules • Safety Inspector can expel Bots • Team responsible for knowing rules • Documentation required for components • Overlapping rules- combination applies • Conflicting rules- most restrictive applies

  12. Weight Requirements • 10 to 15 lbs (20 lb for walker bots) • Includes all attachments and weapons

  13. Size Requirements • 4 by 8 foot fully extended

  14. Speed Requirements • At least 6 inches/second minimum speed • Variable speed in both directions • Slowest speed must be less than 1 foot/sec

  15. Construction Requirements • No exterior foam or foam covering wires • No Toxic metals • Safety covers on all sharp corners • Safety restraints on pinch/motion hazards • Class II lasers or magnets allowed on exterior • No offensive appearance or black lights • > ¼ inch letters for Bot name on exterior

  16. Guard/Restraint Requirements • Guards must be attached to Bot by mechanical means • No vise grips, C-clamps, or tape allowed

  17. Power System Requirements • Electric motors, pneumatics, and springs are approved • No hydraulic or fuel powered propulsion

  18. Electrical Requirements • Maximum 28 volts (24 volts DC nominal) • No AC power or liquid cooling allowed • Wiring must be insulated • Batteries securely mounted • Lead-acid batteries are spill and leak proof • Direct wired, mechanical master switch • No non-electrical tape allowed, i.e., duct tape • No push button on/off switches allowed

  19. Control Requirements • Maximum 2 operators • Bot shutoff < 1 second after transmitter turned off • Certain external control equipment allowed • Tethered control is not allowed • Spektrum BR6000 Receiver recommended • Spektrum AR7000 Receiver not allowed • IFI and Spektrum controllers not subject to impound • Crystal-based controllers can be used with limitations

  20. Activation/Deactivation Requirements • “Completely” safe when deactivated • Maximum 30 second activation time • Maximum 45 second deactivation time • No assembly or disassembly allowed for shutoff • Can’t place body in hazardous position • Can’t place hand more than 2 inches inside Bot • Can’t need more than 1 person to perform • No more than 2 “special” tools with 1/8 clearance

  21. Pneumatic Requirements • Compressed air only and manual shutoff valve • Maximum 150 psi, 8 cubic feet volume @ STP • Relief valve set at 130% operating pressure • Pressure gauge max reads > 20% and < 200% • Certified at 150% operating pressure w/proof • Manual purge valve(s) discharges < 60 seconds • System secured to non-load bearing surfaces • No direct connection to battery heat sink

  22. Weapon Requirements • < 90 seconds for spinning weapons to stop • Add/remove modular weapons under 30 min • No electrical/electromagnetic weapons • No arena fouling weapons • No obscuration weapons • No mechanism fouling weapons • No explosives/flammables • Projectiles, coverings, airbags are limited

  23. Weapon Requirements • Spring weapons compress at 20 lbs or less • Loss of signal does not cause spring to release • Hand held homing lasers not Class 3B or higher • Flywheels must be secure, not affect Bot control, and comply with 30 second shutdown rule • Flywheels must be powered by Bot and can not start up before match begins

  24. Special Cases • Multibots • Autonomous Bots • Hoppers • Hovercraft • Flyers

  25. Job Aids • Inspection Directions • Inspection Request Form • Internal Inspection Checklist • Functional Inspection Checklist
