Improved stepper motor systems support more applications

Stepper motor systems deliver more precision than standard variable-speed motors without the expense and complexity of servo motors, and newer high bus voltage options provide additional flexibility. See 5 motor technologies, common uses.

An engineering breakthrough from Festo combines the simplicity of pneumatics with the benefits of electric automation. The new Simplified Motion Series (SMS) takes proven spindle axes, toothed belt axes, mini slides, electric cylinders, and rotary actuators and integrates them with an onboard-servo drive. Users commission two-position functionality via onboard push buttons with no additional software needed. IO-Link control can be used for flexible, multi-position applications. It received 2021 Engineers’ Choice recognition in the Motion Control – Drives category. Courtesy: Festo

Technology suppliers are embracing open-source automation. For example, the recently introduced Bosch Rexroth ctrlX Automation platform follows open automation principles. Based on a Linux operating system, the Bosch Rexroth ctrlX Core control system is designed as an open industrial automation platform, allowing customers the maximum freedom to apply or adapt their control systems in whatever direction they see fit.

An actor robot runs on a playpen trying to catch the visible green food, while an observer machine learns to predict the actor robot's behavior purely through visual observations. Although the observer can always see the green foods, the actor, from its own perspective, cannot due to occlusions. Courtesy: Creative Machines Lab/Columbia Engineering

Robot displays empathy to a partner robot

A robot has learned to visually predict how its partner robot will behave, displaying a glimmer of empathy, which could help robots get along with other robots and humans more intuitively.

Predicting robot movement, collective behavior

Engineers have proposed a principle where active matter systems can spontaneously order, without need for higher level instructions or even programmed interaction among the agents, which has been shown in shape-changing robots.
