They represent a significant leap forward in terms of functionality and ease of use, offering a solution to many of the issues that have traditionally plagued servo motors and controllers.

The hole covering uses cuttings of pipe attached to a cable connecting to a servo. The motors are isolated inside a box to keep the wires clear and area all able to be powered with 5 V.

Pretty much every project I've done just lately has required me to test out some servos and experiment with their positions before they go into the assembly. I usually make a quick servo tester on ...

Created using 3D printer parts, a handful of stepper motors, and an Arduino Nano development board, the wire bending machine can be programmed to create a wide variety of different shapes and angles.

Animate then does the interpolation between the different shapes, producing the servo positions needed for each frame. He uses an AS3 script to send those positions off to an Arduino.

Design engineers have long struggled with manual calculations and spreadsheets to properly size servo motors and drives for new machines. A recently launched update of Mitsubishi Electric’s Motorizer ...
