WebMobile Extendable Robot Arm (MERA) is a movable robot arm with a novel 2-DOF scissor mechanism for reaching a high place and positioning an end-effector. MERA is composed of a locomotion vehicle with a rotation table and a 4-DOF extender arm, itself made of two layers of the 2-DOF scissor mechanism arranged in series. Websingularity configurations must be avoided. In this paper first we shedlight on Smokie robot and WAM arm and choose the joints and links. Then the D-H parameters are derived and joint limits are specified. Next the Jacobian matrices are computed and singularity points are derived through their determinants.
