Lynxmotion's Smart Servo (LSS) actuators which are part of the new Servo Erector Set (SES) V2 system can be used to create all kinds of robots. In this post, the three degree of freedom (3DoF) arm is described, along with a variety of accessories. Curious to know the differences between Lynxmotion robotic arms? A table is provided showing SES V1 and SES V2 robotic arms.
Although this post was about using the MG996 in a Lynxmotion biped, the bracket system is the same and provides a detailed explanation:
It’s really hard to make brackets which can be used with a variety of servos, since there are almost no standards in the RC servo industry except for voltage and signal.
