THE APPLICATION & SOLUTION Current robotics research is generating some very unique applications, and one particularly interesting field is ‘swarm robotics’. These applications seek to mimic the behaviour of simple creatures such as ants, where the ‘intelligence’ is observable at the swarm/group level. Our customer for this
This blog post is part two of a 2-part series. Part one was a quick recap of how LRA’s work and how they are driven by dedicated driver ICs. This part is about what happens when the LRA’s don’t work entirely as expected with selected

Introduction Our haptic feedback evaluation kit is an inexpensive tool for everyone interested in implementing a vibration alerting or haptic feature into a project. It allows application engineers and designers to understand the performance of the various actuators that we produce. It can also be
We recently added a new tutorial for the M20-200 Haptic Feedback Evaluation Kit, which looks at driving multiple LRAs from a single source. Unfortunately, driving multiple LRAs at the same time is extremely problematic for a single haptic driver as many of the excellent
Introduction When it comes to mounting motors, a common solution is to use adhesives or glue. Even some of our coin motors and LRAs come with special backings to help keep them in place. However, these adhesives need to be carefully selected as they can
We recently published a new tutorial for our Haptic Feedback Evaluation Kit that explores how to play music or other audio signals on a vibration motor or LRA. Using the great new “Audio-to-Vibe” feature in the DRV2605 and the 3.5mm audio socket on the Haptic
In this article, we’ll clear up a confusing difference in terminology and attempt to create a common language surrounding vibration frequencies. The problem arises because in normal conversation we might refer to a single vibration effect as ‘a vibration’. For example, you might say your
We’re often stressing how a vibration motor’s voltage, vibration amplitude, and vibration frequency are interrelated – essentially the voltage controls the motor speed which in turn directly affects the frequency and amplitude. Application Bulletin 029 covers this in full. Other factors obviously help determine the profile
If you are looking for a quick overview of how linear resonant actuators work, then watch our video application bulletin below. Some of the concepts have been discussed in Application Bulletin 020: Understanding Linear Resonant Characteristics, but now you get to everything in action! In addition
