“…In this way, the power supply, power, and communication cables can be easily insulated. This improves the ability of robotic systems to work in a clean or aseptic environment (Antonescu & Petrescu, 1985;1989;Antonescu et al, 1985a;1985b;1986;1987;1988;1994;1997;2000a;2001;Atefi et al, 2008;Avaei et al, 2008;Aversa et al, 2017a;2016d;2016e;2016f;2016g;2016h;2016i;2016j;2016k;2016l;2016m;2016n;2016o;Azaga & Othman, 2008;Cao et al, 2013;Dong et al, 2013;El-Tous, 2008;Comanescu, 2010;Franklin, 1930;He et al, 2013;Jolgaf et al, 2008;Kannappan et al, 2008;Lee, 2013;Lin et al, 2013;Liu et al, 2013;Mirsayar et al, 2017;Ng et al, 2008;Padula, Perdereau & Pannirselvam, 2008;2013;Perumaal & Jawahar, 2013;Petrescu, 2011;…”

The Stewart's leg is used today in the majority of parallel robotic systems, such as the Stewart platform, but also in many other types of mechanisms and kinematic chains, in order to operate them or to transmit motion. A special character in the study of robots is the study of inverse kinematics, with the help of which the map of the motor kinematic parameters necessary to obtain the trajectories imposed on the effector can be made. For this reason, in the proposed mechanism, we will present reverse kinematic modeling in this paper. The kinematic output parameters, ie the parameters of the foot and practically of the end effector, ie those of the point marked with T, will be determined for initiating the working algorithm with the help of logical functions, "If log(ical)", with the observation that here they play the role of input parameters; it is positioned as already specified in the inverse kinematics when the output is considered as input and the input as output. The logical functions used, as well as the entire calculation program used, were written in Math Cad.

“…This results in a "forced" drive balancing from the transmission, which makes the operation of the assembly to be correct but rigid and with mechanical shocks. Such balancing is not possible when the actuators directly actuate the elements of the kinematic chain without using mechanical reducers PETRESCU, 1985;1989;ANTONESCU et al, 1985a;1985b;1986;1987;1988;1994;1997;2001;ATEFI et al, 2008;Avaei et al, 2008;AVERSA et al, 2017a;2016d;2016e;2016f;2016g;2016h;2016i;2016j;2016k;2016l;2016m;2016n;2016o;AZAGA;OTHMAN, 2008;CAO et al, 2013;DONG et al, 2013;EL-TOUS, 2008;COMANESCU, 2010;FRANKLIN, 1930;HE et al, 2013;JOLGAF et al, 2008;KANNAPPAN et al, 2008;LEE, 2013;LIN et al, 2013;LIU et al, 2013;MIRSAYAR et al, 2017;NG et al, 2008;PADULA;PERDEREAU;PANNIRSELVAM, 2008;2013;…”

Today, robots are increasingly present in the machine building industry, sometimes even in some sections to replace workers altogether, due to the high quality of their work, repetitive, without stopping or pausing, without any manufacturing and assembly scuffs. In this paper, one presents the mechanisms with bars and gears, which are planetary mechanisms for robot automation and mechatronics, structurally-topological. The gears and bars consist of at least one movable articulated bar and one of the cylindrical, tapered or hipoidal gears. Only gears with circular or straight toothed gears, in which the relative position of the rotation or translation axes does not change, shall be considered. The topological structure of the gears and gears is characterized by a kinematic chain with articulated bars and at least one kinematic chain with gears. The kinematic chain may be chain open (with a fixed rotation joint) or closed chain (with at least two fixed joints). The kinematic chain with gears is attached to the kinematic chain with bars so that at least two gear wheels have centers in the bars of the bars and some wheels may be integral with the bars. In practice, some of these gears with gears and gears are known as planetary gears with cylindrical, conical or hipoidal gears.
