Robots provide many benefits for companies across a diverse range of industries. One of the best benefits of robot technology is cost savings, therefore freeing up company resources to invest in other revenue-growing opportunities.

Most robots come with collision software to help prevent accidents that can lead to expensive damage. However, this software isn’t nearly as fast as it needs to be to actually prevent a collision and minimize or eliminate damage.

With RAD’s range of advanced patented Collision Sensors, RAD’s collision sensors mechanically detect when the robot arm has encountered an obstruction, absorbing the crash energy without releasing the air pressure in the collision sensor.

Keeping the air in the collision sensor prevents tooling “sag” and eliminates the effects of compressed air being released into the environment. The collision sensor quickly signals the robot to stop (within 2-8 milliseconds)—thus preventing costly damage to equipment and tooling.

Understanding the Benefits of RAD Collision Sensors Response Time

RAD collision sensors can stop a crash within 2 to 8 milliseconds—that’s between 2 and 8 one-thousandths of a second, which is faster than human response time, which is typically only as fast as 13 milliseconds.

Upon detecting the impact, RAD’s collision sensor maximizes uptime by automatically returning to within 0.0005” (0.013mm) in x, y, and z dimensions and to within ± 0.017° rotationally of its starting position to maximize uptime and eliminate the need for human intervention.

RAD’s collision sensor models also provide additional pneumatic and compliance benefits, including:

  • Allowing pneumatic adjustment so the user can easily change the amount of resistance the unit must encounter before signaling a collision.
  • Having a compliance adjustment feature that lets the user determine the amount of deflection allowed before a signal is sent to the robot’s E-stop or controller.

Collision sensors act as insurance to protect your robot. Even embedded robot language can’t stop an accident as quickly as a RAD collision sensor, and if a collision is detected, the robot won’t reset automatically.

Invest in Cost Savings and Asset Protection

By investing in cutting-edge collision sensors for your robots, you invest in long-term cost savings.

Think about it. One collision sensor alone can protect a gripper that could cost $30,000. Every millisecond counts when protecting your investment!

Even when purchasing a new robot, embedded software can’t respond like RAD collision sensors. Standard robot language attempts to stop the robot once a collision is sensed much later, sometimes 15 to 18 milliseconds seconds, costing you precious time and money in the event of a crash. 

Investing in a collision sensor can help protect your investment and prevent the need to replace expensive tooling, all as the result of a collision that could have been prevented or at the very least mitigated.

Stop Collisions and Protect Your Robots

Are you unhappy with the software included with your robot in regards to its collision response time? To create a reliable solution, prevent damage to your robots, and enforce safety, investing in the right technologies is always a smart choice. 

When collisions can result in lost revenue, reduced production, and waste, it’s time to invest in a sensor that can protect your assets. With RAD’s state-of-the-art collision sensors, you can invest in the best protection for your robots!

Chromalloy Nevada (a manufacturer of jet aircraft engine vanes and blades), was one of the first to purchase RAD’s C-8800 Heavy Duty 5C Collet Gripper. With 8X the grip force of the previously used RAD C-8700 Collet Gripper, the C-8800 allowed Chromalloy to increase their production 300% by enabling them to redesign their wax molds to hold three molds per tree vs. the original one mold per tree. 

Pick & Place Precisely on Either the O.D. or I.D. with RAD’s C-8800 Collet Gripper!

Rapidly Pick and Place your uniformly sized objects with a RAD C-8800 Collet Gripper! Unique design enables the collet to grip your part on either the outside diameter (O.D.) or inside diameter (I.D.). Pneumatically adjustable 360° clamping force enables rapid part transfer and allows efficient handling of a wide variety of parts from lightweight delicate parts to heavy more rugged parts. The C-8800 Collet Gripper can also function as a workholding device for grinding, deburring, or polishing operations.
