“…The damping factor is only added to the minimum singular value of a Jacobian matrix. In addition, Megalingam et al [ 13 ] proposed singular separation to determine the singular direction of Kinova robots, and then avoid joint movement to pass through singular points. References [ 14 , 15 ] also proposed similar analysis methods to analyze singular directions, while these methods are not universal.…”

“…All these observations motivate the current study. In this paper, we concentrate on singular configuration analysis and singularity avoidance of co-bot, taking the JACO2 robot of Kinova Robotics company as an example [ 4 , 13 ]. It has seven DOF (degrees of freedom), with weight of 5.5 kg, a load of 1.5 kg, and a maximum arm span of 98.4 cm.…”

Recently, robotic sensor systems have gained more attention annually in complex system sense strategies. The robotic sensors sense the information from itself and the environment, and fuse information for the use of perception, decision, planning, and control. As an important supplement to traditional industrial robots, co-bots (short for co-working robots) play an increasingly vital role in helping small and medium-sized enterprises realize intelligent manufacturing. They have high flexibility and safety so that they can assist humans to complete highly repetitive and high-precision work. In order to maintain robot safe operation in the increasing complex working environment and human–computer intelligent interactive control, this paper is concerned with the problem of applicant accuracy analysis and singularity avoidance for co-bots. Based on the dynamic model with load and torque sensors, which is used to detect the external force at the end of the robot, this paper systematically analyzes the causes of singularity phenomenon in the robot motion control. The inverse solution is obtained by analytical method and numerical method, respectively. In order to ensure the smooth and safe operation in the whole workspace, it is necessary for a robot to avoid singularity. Singularity avoidance schemes are utilized for different control tasks, including point-to-point control and continuous path control. Corresponding simulation experiments are designed to verify the effectiveness of different evasion schemes, in which the advantages and disadvantages are compared and analyzed.
