A suite of supporting tools for preparing a client satellite to be refueled, comprising: a suite of tools each having a specific function, each tool having a drive shaft and tool section configured for its specific function; a common tool base to which each of said suite of tool tips are permanently attached, said common tool base including a housing with a grasping interface on one side thereof configured for robotic grasping by an end effector attached to a distal end of a robotic arm mounted on a servicing satellite, the grasping interface including a grapple fixture, the other side of said housing configured to have a tool attached thereto and to receive said driveshaft of said tool; two tool mechanism drive interfaces (612, 613) used for enacting functions of a given tool tip via a drive actuator mechanism that is located in the (612, 613) end effector of the robotic arm, one of said two tool mechanism drive interfaces being used to drive specific tool tip on each of the support tools, and the second being use to drive a tie-down stowage mechanism for retaining the common base when not grasped by the robotic arm, a tool mechanism gear train located in said housing that transfers rotation and torque from one of the tool mechanism drive input interfaces (612, 613) to the tool driveshaft via the tool mechanism gear train interface, for actuation of tool function. a tie-down mechanism `active-half, coupled to, and driven by the second tool mechanism drive interface for use when retaining said common base in said tie-down mechanism when it is not being used and is demated from the end effector. a suite of tools each having a specific function, each tool having a drive shaft and tool section configured for its specific function; a common tool base to which each of said suite of tool tips are permanently attached, said common tool base including a housing with a grasping interface on one side thereof configured for robotic grasping by an end effector attached to a distal end of a robotic arm mounted on a servicing satellite, the grasping interface including a grapple fixture, the other side of said housing configured to have a tool attached thereto and to receive said driveshaft of said tool; two tool mechanism drive interfaces (612, 613) used for enacting functions of a given tool tip via a drive actuator mechanism that is located in the (612, 613) end effector of the robotic arm, one of said two tool mechanism drive interfaces being used to drive specific tool tip on each of the support tools, and the second being use to drive a tie-down stowage mechanism for retaining the common base when not grasped by the robotic arm, a tool mechanism gear train located in said housing that transfers rotation and torque from one of the tool mechanism drive input interfaces (612, 613) to the tool driveshaft via the tool mechanism gear train interface, for actuation of tool function. a tie-down mechanism `active-half, coupled to, and driven by the second tool mechanism drive interface for use when retaining said common base in said tie-down mechanism when it is not being used and is demated from the end effector. a housing with a grasping interface on one side thereof configured for robotic grasping by an end effector attached to a distal end of a robotic arm mounted on a servicing satellite, the grasping interface including a grapple fixture, the other side of said housing configured to have a tool attached thereto and to receive said driveshaft of said tool; two tool mechanism drive interfaces (612, 613) used for enacting functions of a given tool tip via a drive actuator mechanism that is located in the (612, 613) end effector of the robotic arm, one of said two tool mechanism drive interfaces being used to drive specific tool tip on each of the support tools, and the second being use to drive a tie-down stowage mechanism for retaining the common base when not grasped by the robotic arm, a tool mechanism gear train located in said housing that transfers rotation and torque from one of the tool mechanism drive input interfaces (612, 613) to the tool driveshaft via the tool mechanism gear train interface, for actuation of tool function. a tie-down mechanism `active-half, coupled to, and driven by the second tool mechanism drive interface for use when retaining said common base in said tie-down mechanism when it is not being used and is demated from the end effector.
