A hybrid transmission for use with a vehicle having an engine has an electric-only mode where the engine is off and a hybrid mode where the engine is on. The hybrid transmission includes an engine connection member configured for connection with the engine, a motor/generator unit configured to selectively operate as a motor, a transmission gearing arrangement, and a transmission input member connected with the transmission gearing arrangement. A torque transfer device is controllable to transfer torque from the motor to the transmission input member upstream in power flow from the transmission gearing arrangement, and a starter gear set includes a planetary gear set positioned in power flow between the engine connection member and the motor. The starter gear set is selectively engageable with the transmission input member and the engine connection member.

A muscle-like actuator comprises a motor with a rotatable drive shaft and a string with a shear thickening fluid (STF) embedded therein. One end of the string is attached to the drive shaft and the other end is connected to a load to form a twisted string actuator (TSA). By controlling the speed and current of the motor, the characteristics of the actuator can be changed. Multiple strings may be located in a flexible soft tube to improve the mechanical properties of the actuator.

A remote controller includes a main body, a dial wheel mechanism arranged at the main body, and a controller configured to obtain rotation angle information of the dial wheel mechanism and control movement of an external device according to the rotation angle information. The dial wheel mechanism includes a support, a positioning member disposed at the support, and a rotating member rotatably disposed at the support. The positioning member includes an elastic arm. The rotating member is configured to rotate relative to the support, causing the elastic arm to abut against the support and to be elastically deformed.

Systems and methods for securing a remotely operated vehicle (ROV) to a subsea structure during cleaning, maintenance, or inspection of the structure surface are provided. In one or more embodiments, an attachment mechanism includes a pair of grasping hooks that are raised and lowered when driven by a motorized drive. In one or more embodiments, an attachment mechanism includes a rigid holder having a mechanical stop and connected to a swing arm, the swing arm configured to rotate inward, but not outward beyond the mechanical stop. In one or more embodiments, an attachment mechanism includes a plurality of linked segments in series, each connected at a plurality of pivot points. A pair of wires passes through the plurality of linked segments and connects to a pair of pulleys that extend or retract the wires, thereby rotating the plurality of linked segments.

A drive assembly utilized in combination with slide out includes a beam attached to a beam guide in an arcuate support rail that is attached to the slide out. The beam may have a first row of teeth and a second row of teeth thereon, where the first row of teeth and the second row of teeth extend parallel to each other on opposite sides of the beam. In addition, the teeth in the first row of teeth are offset relative to the teeth in the second row of teeth. The drive assembly further includes a drive gear having a first gear wheel that engages the first row of teeth and a second gear wheel that engages the second row of teeth, as well as an actuator coupled to the beam to selectively extend and retract the beam. The beam may deflect with respect to the arcuate support rail based on its location and the location of the beam guide to aid in leveling of the slide out.
