Industrial Robots – Highly Reliable Wireless Solutions Instead of Cable Wear on Robots

R3 Solutions provides the wireless technology that steps in when a cable on a robot fails. Instead of hours of production downtime, operations can resume in just a few minutes.

Overview

Industrial robots are among the most productive pieces of equipment in a manufacturing facility—and at the same time, among the most sensitive. Grippers, welding guns, and tools are supplied via cables and hoses in what’s known as a “dresspack,” which must withstand the robot’s constant twisting and bending movements. It is precisely this continuous stress that makes cables a frequent weak point: over time, they wear out, become twisted, and eventually break.

If such a connection fails, it’s rarely just a single robot that comes to a standstill. Often, an entire cell or line is affected. Valuable production time is lost while the cause is identified, the replacement part is procured, and the damage is repaired. In synchronized production lines, every minute counts. R3 Solutions offers a solution that restores operation in minutes.

Typical Industry Challenges

Cable failure is the most common cause of downtime

Constant movement in the dresspack leads to wear, twisting, and cable breakage. In robotic cells, this is one of the most common causes of unplanned downtime.

High Costs Due to Unplanned Downtime

A minor cable defect can bring an entire production line to a halt. Diagnosis and repair take time, and every minute of downtime incurs follow-on costs.

Delays caused by fixed maintenance intervals

Often, a complete repair is not possible until the next maintenance window. Until then, a reliable temporary solution is needed to ensure continued operation.

Quick deployment without specialized knowledge

In an emergency, the temporary solution must be ready for use without time-consuming setup and regardless of the robot type.

How R3 Solves These Challenges

R3 Solutions takes a different approach here than with fixed wireless networks: The Robot Emergency Kit is a pre-assembled emergency solution that, in the event of an emergency, bridges the failed cable link and restores the robot cell to full production within minutes.

Robot Emergency Kit

Plug-and-play wireless replacement in case of cable failure on robots.

  • Ready to use in minutes: Installed and operational in less than ten minutes when needed, instead of lengthy diagnostic and repair times.
  • Cable-like performance: Transmits control protocols such as PROFINET deterministically and with low latency using EchoRing technology.
  • Also suitable for continuous operation: Not only provides a short-term workaround, but ensures continued operation until scheduled repairs can be performed.
  • Complete package: Includes Bridge-E wireless modules, antennas, installation cables, and device-specific adapter kits, compatible with common robot systems.

Bridge E

For safety and control applications with real-time requirements and high synchronization.

  • Determinism: Time-slot-based signal transmission, packet loss rate of 0.000000001 %.
  • Real-time communication: Latencies of up to 2 milliseconds are possible.
  • Safety-compliant: PROFIsafe, CIP Safety, and others are transmitted transparently.
  • Proven in practice: Years of use by European and American OEMs.

Typical Project Workflow

Project Assessment

Project analysis, functional safety requirements, protocol selection.

Network Solution Plan

Success Stories

Loading and Unloading a Drying Oven via a Wireless Control Network

The customer wanted to further automate the loading and unloading process of its drying oven. Wired control of the transport carts was not physically feasible: The extreme temperature fluctuations and the harsh environment of the kiln had repeatedly caused failures in earlier, cable-based solutions.

Maintenance-free wireless control of turntables for hose production

Turntables are a special case in automated production. Due to their rotational movements, the use of cable connections is virtually impossible. Sliding contacts are an alternative, but they often result in downtime. The obvious solution is therefore control via a wireless network.
