Abstract: Modular components may be used to build a robotic manipulator. A subset of the modular components can be selected to build the robotic manipulator based on a schematic. The subset of modular components can be assembled in different combinations to build the robotic manipulator. Using one of the combinations of the subset of modular components, the robotic manipulator can be built.

Abstract: The invention relates to the field of mining, namely, to the oil and gas extraction, hydrogeologic, engineering and the geologic and water supply industry and provides an apparatus for the cutting of slot-like key seats in the well bore zone of productive strata by hydraulic abrasion.

Abstract: The invention includes a method of increasing of the well rate of exploitation and recharge wells, comprising a means of decreasing the stress state in the well area by constructing of slot-like discharge key seats, wherein the slot-like key seats have a screw-like shape, wherein preliminary internal rock friction angles ? are determined for a rock composing a productive strata, and a pitch of the slot key seat screw is selected such that the tangent of the angle of deviation of the slot surface from the ? vertical will be between tg(45??/2)?tg(?)?1/?3, where 92 —is the internal rock friction angle where the key slot is being made.

Abstract: A system for increasing the productivity of oil, gas and hydrogeological wells has means for cutting slots only in a near well zone so as to perform a partial unloading of the well and to remove a part of support stresses, and means for cyclically treating well with a formation-treating substance so as to remove a remaining part of the support stresses, with controlling a density of a formation and correcting the cyclical treatment in correspondence with the density of the formation.
