In this tech short, we will go over how to simulate screw tightening tasks using the screw tightening plugin in ROBOGUIDE. This walkthrough introduces the core concepts behind torque application with CRX series robots and shows how simulation can be used to better understand joint loading before deployment. By exploring these capabilities, we can make more informed decisions about robot selection, tooling setup, and optimal working postures.
We begin by outlining why torque simulation matters. When a robot fastens a screw or similar fastener, its joints must resist external torque forces. Accurately estimating these forces in a virtual environment helps reduce risk and improves reliability in real world applications. From there, we move into the setup of a work cell, including how to add a CRX robot, define payload properties, and correctly configure the user tool. Proper setup is essential because payload data and tool orientation directly influence joint load calculations.
Next, we walk through how to use the screw tightening plugin itself. We will go over how to perform a simple joint load estimation at a single position, followed by a closer look at execution modes and how torque values are applied within the simulation. We will also review how results are displayed, including the visual indicators that highlight potential risks such as alarms caused by excessive load or less favorable robot positions.
As the video progresses, we expand into more advanced workflows. We will go over how to log and analyze simulation results, making it easy to compare different robot postures and identify the most efficient setup. We also introduce how to configure a TP program to evaluate multiple fastening points in one run, allowing for more comprehensive testing across an entire process.
Finally, we touch on the importance of validating simulation results on a real robot using built in tools like load check, reinforcing how simulation and real world testing work together.
