Therefore [Y1 , Y2 ] = −[ B1 , B2 ] , [Y1 , Y3 ] = [ B2 , B3 ] , [Y2 , Y3 ] = [ B1 , B3 ] and τ 2 = span( m1 , m3 ) . a 3 ) For TTR we have Y1 = (0 , m1 ) , Y2 = (0 , m2 ) , Y3 = (ω , m3 ) and B1 = Y3 , B2 = Y2 , B3 = Y1 . Now [Y1 , Y2 ] = −[ B2 , B3 ] , [Y1 , Y3 ] = −[ B1 , B3 ] , [Y2 , Y3 ] = −[ B1 , B3 ] and τ 2 = span( m1 , m2 ) . , b2 (t0 ) × b3 (t0 ) = 0 . This is possible iff ∠( o1 , o2 ) = ∠( o2 , o3 ) . A3 (u) is a subalgebra iff CA = τ 2 in a regular position is valid and this is possible iff ω ⋅ b2 = 0 , ω ⋅ b3 = 0 in a regular position, so we have the following statements.

We have the following cases: a) Let c 2 ⋅ c 3 ≠ 0 at (u) . Then a motion through the point (u) is nontrivial asymptotic iff all joints work and the joint velocities of the prismatic joints satisfy the relationship c 2 : c 3 in the cases RTT, TTR and −c 2 : c 3 in the case TRT. 51 Asymptotic Motions of Three-Parametric Robot Manipulators with Parallel Rotational Axes b) Let c 2 ⋅ c 3 = 0 at (u) . Then a motion through the point (u) is nontrivial asymptotic iff the revolute joint and only the prismatic joint whose axis is parallel to the axis of the revolute joint, work.
