Abstract: According to an aspect, a device may include a shaft, a tool portion including a first arm and a second arm, and a split rolling joint including a first curved portion and a second curved portion. The second curved portion may be coupled to the shaft. The first curved portion may include a first split portion and a second split portion. The first split portion may be coupled to the first arm. The second split portion may be coupled to the second arm. At least one of the first split portion and the second split portion may be configured to roll with respect to the second curved portion such that at least one of the first arm and the second arm can move towards or away from each other.

Abstract: According to an aspect, a device may include a first member, a second member, and a wrist mechanism disposed between the first member and the second member. The wrist mechanism may include a first cylinder portion coupled to the first member, and a second cylinder portion coupled to the second member. The first cylinder portion may be rollably engaged with the second cylinder portion such that movement of the first cylinder portion with respect to the second cylinder portion is configured to cause the first member to move in at least two directions with respect to the second member. The second cylinder portion may be positioned with respect to the first cylinder portion such that a longitudinal axis of the second cylinder portion is orthogonal to a longitudinal axis of the first cylinder portion.
