robolink® articulated arm robot

What is a robolink®?

robolink® is an articulated arm robot, which can be equipped with various tools such as grippers, electromagnets, suction cups, cameras, etc. The robolink® arm can be easily configured to ensure a short commissioning time and an economical solution for several different applications. Available in 4 and 5 degrees of freedom, robolink® is flexible enough to solve applications in many different industries.

What maximum payload can the robolink® articulated arm robot lift?

robolink® carries up to 3kg payload. Visit our online shop to find out which versions support which payloads.

What is meant by the range and nominal range of the articulated arm robot?

The nominal range provides the working area in which the robot can operate in the long term. In the short term, the robot can also work in the area of maximum range.

What is the range of robolink® articulated arm robots?

The range of our robolink® extends from 510mm to 790mm. Visit our online shop to learn more about the range of the individual versions of robolink®.

Is the articulated arm robot always the best choice for my application?

There are countless advantages that robots can offer, such as relieving us of boring or difficult tasks, increasing efficiency and improving productivity in factories and companies. Robots will not be the best solution for every task, but with tests and 3D simulations we are able to quickly analyse the application and determine what can best solve the problem.
Whether the articulated arm robot is always the best choice is something we would be happy to discuss with you in a personal meeting, because sometimes other kinematics are easier to integrate into processes.

Is it possible for me to have a look at a robolink®?

Basically you have the option of requesting an appointment with our sales team, live or virtually (via Microsoft Teams).

Which end effectors are used with robolink®?

The robolink® can be equipped with practically any end effector as long as it is within the payload of the robot. This may include electromagnets, grippers, suction cups and many other tools.
At RBTX.com, our online marketplace for robotic components, you can buy various components from our partner suppliers.

Which cables are used with robolink®?

For robolink® you can use many different cables and hoses, from pneumatic tubes to sensor cables. The possibilities are almost unlimited!
You can accommodate 2x8mm cables per side in the robolink® DP. In addition, there are external energy chains for the robolink® DP and robolink® DC, which you can fill easily.
 

Can I negotiate bends with robolink®?

Only conditionally, because we have to travel to several points on a bend in order to complete the curve. Because the cornering is not quite round.

What does the 7th axis mean?

The 7th axis is a linear axis for moving a robot.

With which manufacturers is the 7th axis compatible and easily integrated?

  • Universal Robots UR3, UR5 and UR10
  • igus robolink DP4, robolink DP5, robolink DC

What do I need to control the 7th axis?

For igus robots, the igus Robot Control.

For UR Robots a UR Cap solution. We offer these in our shop (our part number DDLE-UR-0001)

igus® dryve systems

What is igus® dryve?

igus® produces two motor control systems, which are suitable for DC motor types and diverse applications. You can read more about this below.
 
D1 dryve
The drylin® D1 dryve is designed for direct control of stepper, DC and EC/BLDC motors and on single axes such as linear belt drives or single lead screw drives. If several D1 dryves are connected via a higher-level control system (PLC, industrial PC, etc.), it can also be used in multi-axis systems such as delta robots or linear robots.
 
D3 dryve
The drylin® D3 dryve is designed for direct control of DC motors on single axes, such as belt drives or lead screws for simple, linear movements at different speeds and from different starting positions.

What is the difference between the D1 dryve and the D3 dryve and where are they used?

The drylin® D1 dryve is a motor control system (for EC/BLDC, EC, stepper and DC motors) that was developed to offer a universal motor control system for all igus linear systems. The usual long commissioning times of motor control systems can be reduced to a minimum by reducing the settings to the minimum necessary.
The D1 dryve can be used in simple automation applications as well as complex industrial plants
 
The drylin® D3 dryve is a motor control system (for DC motors), which was developed to offer needs-based solutions for the simplest automation tasks and at the same time reduce the usual long commissioning times to a minimum.

Which motor can I control with the D1 dryve or D3 dryve?

  • D1 dryve: all igus stepper, DC and EC/BLDC motors as well as motors in similar performance classes from other manufacturers.
    Both in controlled operation, with and without position monitoring, and in closed loop operation (comparable to a servo motor).
  • D3 dryve: all igus DC motors as well as DC motors from other manufacturers (max. 2.5A continuous motor current)

 

Which power supply do I need for the D1 dryve or D3 dryve?

  • D1 dryve: the logic voltage supply is 12-24V and the load voltage supply 12-48V.
  • D3 dryve: 24V/2.5A

Which software do I need for the D1 dryve or D3 dryve?

None!
The D1 dryve has a built-in web server for configuration. By entering the IP address shown on the display of the D1 in a browser of your choice, you can directly access all necessary settings.
 
With the D3 dryve, the few necessary adjustments can be made using small switches such as rotary knobs on the housing.
 

What is required for commissioning the D1 dryve or D3 dryve?

  • D1 dryve: a power supply (12 to 24V) and a PC including Ethernet interface (and cable) are required.
  • D3 dryve: connect a 24V power supply and a motor → and you are ready to go. No complicated software installation or complex wiring of various additional switches and sensors.

Do I need basic knowledge of electrical engineering to operate the D3 dryve motor control system?

The intuitively operated rotary elements allow you to set the speed and force limit of the connected motor without prior knowledge.

D3 dryve: how do I move the motor after it has been electrically connected?

A travel movement can be started by means of the two buttons at the front of the D3 dryve and 2 external potential-free switches.

Can my automated system communicate with the D1 dryve?

With standardised communication protocols such as CANopen or Modbus TCP as gateway, it is easy to connect the system to industrial controllers such as Siemens or Beckhoff. The digital inputs and outputs enable extremely easy communication with industrial controllers but also with low-price open-source modules such as Arduino or Raspberry Pi.

drylin® delta robot

What is a delta robot and where is it used?

A delta robot or parallel robot is a 3-axis robot connected by a common joint above and below the arms to fulfill its main purpose: picking up and placing objects.  
 
The igus® delta robot is available in both a small and a large version: it offers customers with a smaller working range (330mm diameter at a height of 75mm) the possibility of achieving highest speeds. The large delta robot now has twice the reach of the smaller robot (660mm diameter at a height of 180mm), giving customers with a smaller workspace (330mm diameter at a height of 75m) the flexibility to pick up and place objects from more distant locations.
 
A delta robot can be used for standard applications with small parts, such as picking from a conveyor belt or buffer table to a stationary destination or for painting, spraying and repetitive work over a small area.

What is the payload of a drylin delta robot?

The igus® delta robot can lift up to 5kg and press down up to 100N (10kg).

What is the range of a drylin delta robot?

The drylin® delta robot can extend to a diameter of up to 360mm at a height of 75mm.
The larger version of the drylin® delta robot can reach a diameter of up to 660mm in 180mm height.

Which end effectors can be used for the drylin delta robot?

With the end effectors used in the drylin® delta robot, the possibilities are almost unlimited.
These can vary from electromagnets, suction cups and mechanical grippers up to 3D printed gripping tools. All energy and air can be directed via a cable management system to the end plate that holds the end effector, which we can also supply!
At RBTX.de, our online marketplace for robotic components, you can buy various components from our partner suppliers.

How precise is a drylin delta robot?

The accuracy of the drylin® delta robot is +/- 0.5mm.
