Prоblem 1 - True/Fаlse (30 pts) Indicаte if eаch questiоn belоw is true or false. You do not need to show your work. (a) The degrees of freedom can be calculated by using Grubler's formula for any systems with a finite number of joints. (b) There exist holonomic and nonholonomic constraints that are independent. (c) There exist a rotational matrix (Rin SO(3)) such that (R) is skew-symmetric ((R=-R^top)). (d) Given a rotational matrix (Rin SO(3)) such that (Rneq I_{3times3}), there exist a unique (omegainmathbb{R}^3) with (||omega||=1) and a unique (thetainmathbb{R}) such that (R=e^{widehat{omega}theta}). (e) Consider a homogeneous representation of a rigid body (T_{sb}in SE(3)) represented bybegin{equation*} T=begin{bmatrix} R_{sb} & p_{sb} \ 0_{1times 3} & 1 end{bmatrix}.end{equation*}There exist some (R_{sb}) and (p_{sb}) such that (T^{-1}=T^top). (f) If the pitch of a screw motion is finite and non-zero, namely, (0
