Abstract: A robotic inspection system for corrosion detection within external post-tension bridge tendons includes a sensing device. The sensing device is configured to move along a bridge tendon to detect magnetic flux leakage of the bridge tendon as the sensing device moves along the bridge tendon. In addition, the system includes a location device coupled to the sensing device, where the location device is configured to determine the location of the sensing device on the bridge tendon. The system also includes a control station configured to wirelessly interface with the sensing device and the location instrument. The control station is also configured to generate a bridge tendon condition assessment report from the detection of magnetic flux leakage to identify locations and sizes of discontinuities of the bridge tendon.

Abstract: A robotic inspection system for bridge suspender cables includes a sensing device and a transport vehicle. The transport vehicle is configured to move the sensing device along a bridge suspender cable for taking main magnetic flux (MMF) readings as the sensing device moves along the bridge suspender cable. The system also includes a control station configured to wirelessly interface with the sensing device and the transport vehicle. In addition, the control station is configured to generate a bridge cable condition assessment report from the MMF readings to identify locations and sizes of deterioration of the bridge suspender cable.

Abstract: A robotic repair system for high mast light poles includes a support ring having a diameter to fit around a high mast light pole, a guide system secured to and above the support ring, and a platform engaging the guide system and coupled to an actuator configured to move the platform in a first direction, and an opposing second direction. The robotic repair system also includes a repair attachment secured to the platform to repair the high mast light pole, a drive wheel and a motor coupled to and configured to drive the drive wheel and configured to move the repair attachment along the guide system, and an outer guide track secured adjacent to the guide system where the drive wheel is within the outer guide track.

Abstract: A high mast light pole inspection system includes a command center and a transport vehicle. The transport vehicle has a frame configured to be secured around a high mast light pole, and a plurality of sets of wheels. Each set of wheels has a spring mechanism that biases a respective set of wheels inward towards a center of the frame. The plurality of sets of wheels are wirelessly controlled from the command center. In addition, the transport vehicle includes a plurality of cameras mounted to the frame, a power supply coupled to each set of wheels and camera, and a RF digital video transmitter coupled to the plurality of cameras. The transmitter is configured to transmit a wireless multiplexed output of the cameras to the command center.

Abstract: A cable stay transport vehicle and inspection system having an upper frame coupled to a spaced apart lower frame. The transport vehicle is configured to be secured around a cable stay. The transport vehicle includes left upper and lower sets of wheels secured between left side upper and lower frames, and right upper and lower sets of wheels secured between right side upper and lower frames. In addition, a left steering device is coupled between the left upper and lower sets of wheels and includes a left steering gear, and a right steering device coupled to the right upper and lower sets of wheels and comprising a right steering gear. Left and right driving gears are coupled to the left and right steering gears, respectively, and are configured to engage the respective steering gear to turn the transport vehicle when activated.

Abstract: A motorized high mast pole inspection device that is self-powered and autonomous with respect to the internal lever of a high mast pole. The inspection device provides a means for mechanically climbing a vertical, cylindrical, tubular high mast light pole. Video monitoring and recording equipment may be deployed on the device for inspecting high mast light poles.
