Sizing a Battery for an AGV: Part I
Battery selection is one of the most critical AGV design choices, with major impact on performance and cost. Most battery selection procedures begin with a fixed energy budget, often determined early on in the overall design process. But because all losses within the drivetrain detract from the AGV’s available runtime, overcompensating for these losses can drive up battery size, weight and cost.
Better Servo Systems — Part III: Shielding and Installation
Finishing our blog series on grounding, terminations and shielding for servo drive and motor installations, we provide an overview of cable shielding, ground loops and installation best practices.
Adding Functional Safety to Automated Machines: Part III
Safe torque off (STO) is a critical fallback state in many safety functions. Because of its prevalence, it is important to understand how STO works and its advantages over previous methods of reducing machine risk. Let's dive into how STO works and introduce a design that simplifies system complexity.

Better Servo Systems — Part II: Signaling and Terminations
In an earlier blog post, we reviewed the different kinds of grounds you should familiarize yourself with to successfully install servo drive and servo motor systems. For our next topic in this blog series, we will examine different kinds of interface signaling, when to model cable as a transmission line and how to terminate lines to eliminate reflections.
Adding Functional Safety to Automated Machines: Part II
When a machine's original risk relates to its movement during operation, safety functions that stop, hold position or regulate motion can be successful solutions. Some of the most common safety functions include safe torque off (STO), safe operating stop (SOS) and safe brake control (SBC).
