Abstract: Designing intrinsically safe robotic inspection systems used for unmanned navigation and inspection of large tanks with hazardous and explosive atmosphere is challenging. The disclosed methods and devices provide solutions to overcome such challenge. Intrinsically safe devices and methods using a combination of a lighter-than-air blimp with various intrinsically safe subsystems attached to the blimp are presented.

Abstract: A compact, high torque actuator includes a brushless motor, motor control electronics, an inner hollow tube to transmit rotation of an output plate to the input end of the actuator, thus allowing two absolute magnetic encoders to read an absolute position of the input and output of the actuator. The actuator is sealed to operate in fluid environment at high pressures.
