Abstract We have given a generalization of one parameter special Frenet motion to type-2
Bishop motion in Euclidean 3-space E
3
. Type-2 Bishop motion have been defined for space
curve β and then type-2 Bishop Darboux vector of this motion has been calculated for fixed
and moving spaces in E
3
. Also, we have showed that type-2 Bishop rotation for space curves
is decomposed into two simultaneous rotations. One of the axes of this simultaneous rotations
is a parallel of the binormal vector of the curve, the other is the direction of the type-2 Bishop
Darboux vector of the curve.

1 Introduction
Firstly, Yılmaz and Turgut have introduced a new version of Bishop frame using a common
vector field as binormal vector field of a regular frame and called this frame type-2 Bishop
frame. Additionally, they have given the type-2 Bishop spherical indicatrices, [13]. Later,
Kızıltu˜ g and et al have defined slant helices and obtained some characterizations of slant
helices according to type-2 Bishop frame in the Euclidean 3-space [9]. In addition to these
studies, Bükcü and Karacan have given the generalization of one parameter Frenet motion
to Bishop motion in the Euclidean 3-space which is defined by Bottema. They have also
inspired by the article of Barthel and defined Darboux vector of this motion and obtained some
