ABSTRACT
This paper informs about the development of training delta robot Caertec rk 2010 at University of
Zilina. Parallel kinematics of robot is based on three parallelogram mechanisms. Kinematic loops of
Delta robot were counted by the inverse kinematics. For delta robot control and trajectory
programming was developed software. The program allows the simulation, the workspace analysis,
the positions programming and the communication management. The structural design and simulation
has been developed using system CATIA.
Keywords: parallel kinematic structure, parallel robots, delta robots, inverse kinematic analysis,
simulation software
1. INTRODUCTION
The parallel kinematic structure is a closed-loop kinematic chain mechanism whose end-effector is
linked to the base by several independent kinematic chains.
Parallel structures are interesting due to their large stiffness and high positioning accuracy compared
to serial robots. This kind of kinematic structure can be used in many fields but most of them are used
as robots or as numerical controlled machine tools. Specific applications such as spatial, medical,
joysticks and simulators are also possible.
Parallel robots can also be defined as: a parallel robot is made up of a fixed base and of an end-effector
with n-degrees of freedom that are linked together by at least two independent kinematic chains.
Actuation takes places through n-simple actuators. This type of mechanism is interesting because
when the actuators are locked, the manipulator remains in its position (this is an important safety
aspect), and because of the number of actuators and sensors are minimum (Merlet, 2006).
2. DELTA ROBOTS
A delta robot is a type of parallel robot which consists of arms connected to universal joints at the
base. The basic idea behind the Delta parallel robot design is the use of parallelograms.
A parallelogram allows an output link to remain at a fixed orientation with respect to an input link.
The use of three such parallelograms restrains completely the orientation of the mobile platform which
remains only with three purely translational degrees of freedom. The input links of the three
parallelograms are mounted on rotating levers via revolute joints. The revolute joints of the rotating
levers are actuated in two different ways: with rotational (DC or AC servo) motors or with linear
actuators. Finally, a mechanism is used to transmit rotary motion from the base to an end-effector
