A launching tube for use with a liquid filled tank can be sized to accommodate a submersible vehicle for dispensing into the liquid tank. The tank can be an electrical transformer or any other liquid containing tank such as but not limited to a chemical tank. The launching tube can include a valve for insertion into a launching chamber, and a tank side valve for launching of the submersible into the tank. In one form the launching tube includes an antenna for communication with the submersible and/or a base station. The launching tube can also include a sensor such as a camera, as well as an agitator. The agitator can be used to facilitate bubble removal from the inside of the launching tube.

A system for sensing and controlling eye contact for a robot. The system includes a robotic figure with a movable eye. The system includes a light source positioned in the robotic figure to output light through a light outlet of the eye. A light sensor is included that senses light striking surfaces in a physical space in which the robotic figure is positioned including the output light from the light source. The system includes an image processor processing output of the light sensor to identify a location of a target formed by the output light striking surfaces in the physical space and to identify a location of a face of a human. Further, the system includes a robot controller generating eye movement control signals based on the location of the target and the location of the face to position the eye to provide eye contact with the human observer.

A pickup bed tool assembly includes a handle which has a first portion that slidably engages a second portion such that the handle has a telescopically adjustable length. A push bar is pivotally coupled to the handle for pushing cargo into a pickup bed. The push bar is positionable in a deployed position or a stored position. A locking unit is movably coupled to the handle. The locking unit releasably engages the push bar to retain the push bar in either the stored position or the deployed position. The locking unit is actuatable to disengage the push bar thereby facilitating the push bar to freely pivot on the handle. A hook is coupled to the handle to grapple cargo in the pickup bed for pulling the cargo out of the pickup bed.

The present invention provides a handheld robot for orthopedic surgery and a control method thereof. The handheld robot of the present invention includes a main body, a grip, a kinematic mechanism, a tool connector, a tool, a force sensor and a positioning unit. The handheld robot of the present invention combines the position/orientation information of the tool acquired by the positioning unit with the force/torque information acquired by the force sensor, and utilizes the combined information to adjust the position of the tool so as to keep the tool within the range/path of a predetermined operation plan. In this way, the precision of the orthopedic surgery can be enhanced, and the error occurred during the surgery can be minimized.

The present invention provides a lid closing device and a lid closing method, each of which does not require a high degree of accuracy when performing a lid closing operation. A holding portion moves such that a lid is located at a position above a container. Holding of the lid by the holding portion is released at the position above the container. The lid falls to cover the container. Thus, the lid closing operation is performed.
