A mechanical device that has the ability to manage and set explosives cones in the rocks that form the hanging, which can be operated remotely, avoiding the danger of the current state of the art where operators place explosive using bamboo sticks, before detonating them, causing an imbalance in the hanging. The mechanical device also known as cone-holder, is located at the end of an automated and semi autotransportable manipulator arm for releasing hangings.

Provided is a robot hand applicable to purpose for holding various types of objects different in size or shape. The robot hand includes a hand base, a first hand arm having a first butting part and a first adsorption part, a second hand arm having a second butting part and a second adsorption part, and a driving mechanism for moving the first and second butting parts in directions to approach each other or separate from each other by moving the first and second hand arms relatively to each other.

Examples described here include a device that has a housing defining a cavity, and a force sensor. The device also includes a first hydraulic actuator positioned in the cavity, and a second hydraulic actuator positioned in the cavity. The first and second hydraulic actuators move between respectively relaxing modes and thrusting modes along respective longitudinal axes. The longitudinal axis of the first hydraulic actuator is substantially parallel to the longitudinal axis of the second hydraulic actuator. The device also includes a first actuated member coupled to the first hydraulic actuator, and a second actuated member coupled to the second hydraulic actuator.
