Robotic solutions – quick and easy implementation

In combination with the integrated 3D simulation and the option of a teach-in, the parameterisable MOVIKIT^® Robotics software module offers the simplest possible generation of motion sequences. At the same time, the module provides a wide range of functions and a high degree of flexibility for implementing your application.

The MediumModels module expands the functionality to add kinematic models with three or four joint axes, e.g. gantry robots, roller gantries, SCARA robots, delta robots, tripods and quadropods.

What’s more, the MediumModels expansion module also includes the appropriate 3D models of the kinematic models in MOVISUITE^® RobotMonitor and convenient parameterisation of the models in MOVISUITE^®.

The LargeModels module expands the functionality by adding kinematic models with five or six joint axes or at least two orientational degrees of freedom, including for gantry robots, articulated arm robots, tripods and hexapods.

What’s more, the LargeModels expansion module also includes the appropriate 3D models of the kinematic models in MOVISUITE^® RobotMonitor and convenient parameterisation of the models in MOVISUITE^®.

The ConveyorTracking add-on extends the scope of functions of MOVIKIT^® Robotics by adding the option of interpolation in moving coordinate systems. This makes it possible to pick up objects from a running conveyor belt, for example, and place them in a static environment or on another conveyor belt. The robot first synchronises itself with the belt in the Cartesian coordinate system. All other movements are then synchronised with the moving belt, making it possible for the picking procedure to be carried out.

The add-on also supports picking and placing objects from or onto a rotary table. The rotary table can be externally controlled. Alternatively, the rotary table can be synchronously controlled by the robot in such a way that it expands the robot’s degrees of freedom. As a result, a robot with three degrees of freedom can carry out a four-dimensional palletising task, for example.

The MOVIKIT® Robotics addon TouchProbe can be used to precisely measure the current Cartesian position or to perform a true-to-path distance-to-go positioning.

The Touchprobe module makes it possible to carry out precise measurement of the current Cartesian position or true-to-path sensor-based positioning.

When a sensor is triggered or the state of a Boolean variable in the robot program changes, the actual position of the robot on its path is identified in terms of the Cartesian system. When this happens, a defined action can be carried out.

This defined action might be a sensor-based positioning, for example. This involves traveling a specific remaining distance starting from the measured point on the robot's programmed path.

Applications for the Touchprobe function include palletising or depalletising where the height of the parts is variable or unknown and the sensor-based execution of actions.

Overview of functions:

• Touchprobe functions: Measurement and sensor-based positioning
• Registration and deregistration of the Touchprobe function at any point of the motion path
• Several registrations in one robot program
• Parameterisation of the event source, edge, repetition of events (e.g. several measurements) and measurement direction
• Extensive diagnostics via registration, actuation of the trigger, and Touchprobe position in the robot program and according to the 3D simulation

The Circle add-on* extends the range of functions of MOVIKIT^® Robotics by adding the option of circular interpolation.

The circle segments can be parameterised in various ways.

• Circle center and angle
• Circle center and end point of the circle segment
• Intermediate point on the circle segment and end point of the circle segment
• Radius and angle
• Radius and end point of the circle segment

The CollisionDetection extension module of the MOVIKIT® Robotics software module can be used to detect a collision on the tool and other parts of the robot mechanics.

Using the CollisionDetection add-on* means you don't need any expensive sensor technology on the tool or arm joints. This is because the expansion module makes it possible to reliably identify any collision on the tool and other mechanical parts of the robot. This is achieved by continuously comparing the actual status of the robot with its target status as stipulated in a dynamic model.

Collision responses such as the true-to-path emergency stop can be configured in advance or integrated directly into the motion program using parameterisable commands.

Industrial manufacturers are increasingly demanding greater flexibility, precision and time efficiency. They therefore appreciate when they can obtain reliable modules and support straight from a single manufacturer.

SEW-EURODRIVE is the ideal partner for this. We automate kinematics solutions with a mechatronic subsystem that serves as a kit for parallel arm kinematics robots.

These MAXOLUTION® parallel arm kinematics kits consist of controller, axis and mechanical packages. They are easily integrated into machine applications or as autonomous solutions in production processes. They can also be operated as stand-alone solutions.

The modular structure and independent design of the individual system packages enable you to achieve perfectly coordinated kinematics in just a few simple steps. Furthermore, the parameterisable software module MOVIKIT^® Robotics enables a quicker and easier startup.

The MOVIKIT^® Robotics software module includes more than just the option of mapping the motion visually in advance in the 3D view. A simulation of the dynamic properties can also be conducted using the dimensions and masses entered and the robot’s known moment of inertia. This makes it possible for you to determine how big the forces and required torques are for the individual joints and especially for the motors.

This data can be used in the SEW-Workbench drive configuration tool, for example, to design the drive train perfectly to meet your requirements. This saves you costs that can otherwise be generated by oversizing or undersizing.

MOVISUITE^® RobotMonitor is the user interface for the MOVIKIT^® Robotics software module and its add-ons.

It can be used to visualise the parameterised kinematic model and execute it axis-by-axis or using the Cartesian system in jog mode, manually in program mode, or in automatic mode. Furthermore, RobotMonitor contains an editor for the SEW Robot Language that makes it very easy to enter and parameterise the motion sequences by teach-in, using specific coordinates or pose variables.

Up to 20 programs, each containing several hundred commands, can be defined in this way as standard. Further programs without size limitation can be added. During startup, the procedure can be monitored e.g. in step mode using the program pointer and motion pointer.

RobotMonitor can be run on PCs, or on keypads and tablets using a Windows operating system. This provides users with the same interface, no matter which device they use.

Overview of functions (as per the points in the image)

• 1
  3D simulation of the kinematic model:
  This makes it possible to examine the movement from any angle, including when working without a drive in the office or e.g. in the case of simulated drives, on the machine.
• 2
  Manual mode and automatic mode:
  The program can be executed manually and optionally in step mode, or automatically.
• 3
  Speed override:
  Especially during startup, it makes sense to operate at a reduced speed.
• 4
  Buttons for jog mode:
  In manual mode, and for the teach-in, the robot can be moved to the desired position.
• 5
  Editor for the SEW Robot Language:
  The editor makes it easy to create the robot program or adjust standard programs using intuitive, understandable instructions and graphically supported diagnostics.
• 6
  Information and error display:
  The current error status and other useful information is displayed clearly and conveniently as text.

The SEW Robot Language integrated into MOVISUITE^® RobotMonitor offers a complete set of functions that can be entered and parameterised simply and conveniently. Working with the sequential function chart is intuitive and can therefore be learned fast. As a result, the individual commands can be combined – without any additional programming knowledge – to create a sequence that defines the motion sequence of the kinematic model.

Loops, branching and calling up subroutines are all possible, as is the setting of variables. SEW Robot Language can, in turn, interact with the lower-level IEC program, which means special functions can be carried out there. You define the motion sequence using simple commands such as LIN and WAIT, and by setting the coordinate system.

As the range of functions offered by systems and drive technology grows, the operating, visualisation and diagnostic requirements are becoming ever more demanding, too. The SEW-EURODRIVE visualisation hardware has been specifically developed for use in harsh industrial environments immediately next to the machine.

The keypad enables simple handling and also the use of the integrated safety functions such as keyswitches, emergency stop and confirmation button. It goes without saying that we deliver the appropriate accessories in addition to our comprehensive portfolio of visualisation solutions. These include pre-fabricated cables, assembly parts and voltage supply – all from a single source.
