Paired Pouch Motors for Robotic Applications
The pairing of pouch motors or serial pneumatic artificial muscles (sPAMs) can be used to increase their performance in terms of displacement and force. This simple concept was used for the actuation of a simple robotic arm.

Origami-based Vacuum Pneumatic Artificial Muscle (OV-PAM)
A vacuum-based soft linear actuator was developed capable of deformations up to 99.7% of their length and of lifting payloads up to 40 kg. This actuator has a large potential for robotic applications.
