Herein is disclosed a multifunctional tool with replaceable tool tips. The disclosed multifunctional tool may be used as an end-effector on a robotic arm in space. Each tool tip, when in the tool holder, is driven by a common motor. The same motor can also be used to control the orientation of the tool tip about an axis. The tool tips are replaceable in the tool holder by simple and robust means, resulting in a lighter and cheaper multifunctional tool. The tool tips can be variously adapted to perform a variety of functions, including cutting, grasping, drilling, driving, etc. Since the tool may be driven by only one actuator, and the single actuator may be used to drive both the tool and rotation of the tool, mass can be saved. Use of such a multifunctional tool also reduces overall system power requirements, and system complexity.
