Robotic crawler platform systems and methods
View Patent ↗A non-electric robotic crawler platform system and method for logically controlling a pneumatically driven multidirectional multi-motor crawler platform in a confined space that can include Zone 0 and 1 spaces. The system can include a robotic crawler platform and an air logic control system. The robotic crawler platform can include wheels and pneumatic motors. The pneumatic motors can be connected to the wheels. Wheels can be polymer, magnetic, rollers, sprockets for track driven system and other motion systems. The air logic control system can be in fluid communication with the pneumatic motors. The robotic crawler platform and the air logic control system are non-electric. The robotic crawler platform and the air logic control system are made from materials having anti-static properties. A user can provide motion control input to the air logic control system to control directional motion of the robotic crawler platform by controlling any one of or any combination of the pneumatic motors in either a forward or reverse rotation direction. Precision can be obtained through flow/pressure controls either onboard the robotic platform to the motors or exhaust controls plumed exhaust flow regulators from the air piloted shuttle valves.
