The KR CYBERTECH nano ARC product family is optimized for continuous-path applications such as arc welding and the application of adhesives and sealants. The industrial robots offer ideal performance combined with a high power density – for maximum economy at low cost.

Cost-effective, flexible robots for applications such as arc welding, adhesive bonding application or laser cutting

With their new controller structures, the industrial robots of the KR CYBERTECH nano ARC family have extremely high path accuracy and speed. The acceleration values and the new ergonomic design with minimized disruptive contours ensure continuous-path motion at the very highest level – even deep inside the workpieces. With very fine payload intervals of 6 and 8 kilograms, you will find the ideal robot model for your application.
  • Any installation position

    The robot can be floor-, wall- or ceiling-mounted or even installed at a certain angle – exactly in line with your requirements.
  • Software add-ons

    With digital Motion Modes, you can simply adapt the performance of the robot via the robot controller – e.g. for optimized precision or speed
  • Reduction of your TCO

    The long service life and maintenance-free axes 4-6 sustainably reduce your TCO.

  • Suitable for compact cells

    With a compact design and small footprint, the robots ensure optimal utilization of the space in robotic cells.

Extremely fast, uncompromisingly precise continuous-path motion: the hollow-shaft robot impresses with maximum performance at minimum cost. 

6 - 8 Load capacity [kg]

1421 - 1843 Reach [mm] (arm length)


Maximum precision

With their repeatability of 0.04 millimeters, the KR CYBERTECH ARC nano robots work extremely exactly and precisely even at high speed.

Maximum flexibility

The robots can be wall-, floor- or ceiling-mounted or even installed at a certain angle – exactly in line with your requirements.

New KUKA hollow wrist

The 50-millimeter hollow-shaft wrist is a future-oriented innovation: the hollow axis allows reduced main axis motion with short cycle times and utmost precision of movement.

ESD protection

As standard, the robot is protected against uncontrolled electrostatic charging or discharging and is thus equipped for the safe handling of sensitive electronic components.

Streamlined compactness

The industrial robots are particularly light, highly streamlined and exceedingly compact. They deliver maximum performance with minimal disruptive contours.

Maximum freedom

The KR CYBERTECH ARC nano robots have a large workspace to the rear and a long downward reach. This enables them to open up previously inaccessible workspaces.

High flexibility

The use of modern KUKA controllers facilitates the integration of external axes.

KR CYBERTECH nano ARC as ‘Edition’ robot: Cost-effective entry into welding automation:

Simple welding processes enable the cost-optimized use of appropriate robots such as the Edition variant of the KR CYBERTECH nano ARC. It is designed especially for simple arc welding in highly dynamic, price-sensitive markets – which makes it easier for new customers to add automation. The KR CYBERTECH nano ARC HW Edition robot is available with two reaches 1,440 mm und 2,010 mm. It features a hollow wrist with bearings on both sides and a repeatability of 0.04 mm. For the ‘Edition’ robot, too, KUKA has implemented its latest KR C5 controller generation and appropriate software packages.
The KR CYBERTECH nano ARC HW Edition robots are designed for entry-level arc welding applications
