Robot orthogonal

Four observations oci, i,oi2t02 from the perspective centres Pi, Pa with rectangular coordinates xi, yi, zi, xa, y2,22 via two 3x3 orthogonal matrices (Ri, Ra should determine three unknown rectangular coordinates x, y, z of robot table objects. Thus the observationed system is overdetermined] we took notice of this effect by writing a consistent system of observational equations in terms of the expectation operator E. Indeed we have represented the actual observations ai, 5i,Q a,/ a by... 

The Cartesian robot consists of three orthogonal linear links that comprise the arm, and three rotational links that from the wrist system. Figure la shows a typical configuration from this robot class. Cartesian robots are easy to control the controller can be seen as very similar to a six-axis machine tool CNC. Unlike all other robots, this type needs no coordinate transformatimis for linear motions. This makes the robot particularly suitable for linear movements where precise path control is required. The drawback of this class is the volume of its mechanical structure relative to the work volume it offers. 

Cylindrical Coordinate Robots One of the earliest industrial robots belongs to the cylindrical coordinate robot class. Its kinematic structure is shown in Fig. lb. The arm consists of two orthogonal linear links placed on a rotating base. In comparison to Cartesian robots, this configuration offers a much larger work volume relative to the mechanical structure of the arm. The control system needed for linear path control is slightly more complex than for the Cartesian robots (Fig. 2).

The work in [4] includes both the adaptation mechanism as well as a dynamic reconfiguration of the round structure, according to robots that dynamically join and leave the team. This is orthogonal to the current work and thus it will not be considered here. The focus will thus be on the adaptive TDMA mechanism, only.
