As 3D printing technology becomes more ubiquitous and pervasive, printed robot structures are likely to become popular. However, these 3D printed structures have inherent flexibility which causes link deflections and vibrations that lead to difficulties in maintaining gait and produce instabilities during motion. In this paper a biped robot, realized with 3D printing techniques, was modeled and its gait was simulated under position control. Spring and damper elements are used within powered joints to model the link flexibility. Servos were placed at the joints and an open-loop gait trajectory was executed by posing the robot through a series of servo angles. The gait of the printed robot was designed using the model. The printed robot’s stability and accelerations during the motion were characterized with 3-axis accelerometers and gyroscopes mounted on the robot. The acceleration measurements from the printed robot are then compared with the model behavior.

Electromechanical Performance

Electromechanical sensing devices, based on resins doped with carbon nanotubes, were developed by digital light processing (DLP) 3D printing technology in order to increase design freedom and identify new future and innovative applications. The analysis of electromechanical properties was carried out on specific sensors manufactured by DLP 3D printing technology with complex geometries: a spring, a three-column device and a footstep-sensing platform based on the three-column device. All of them show a great sensitivity of the measured electrical resistance to the applied load and high cyclic reproducibility, demonstrating their versatility and applicability to be implemented in numerous items in our daily lives or in industrial devices. Different types of carbon nanotubes—single-walled, double-walled and multi-walled CNTs (SWCNTs, DWCNTs, MWCNTs)—were used to evaluate the effect of their morphology on electrical and electromechanical performance. SWCNT- and DWCNT-doped nanocomposites presented a higher Tg compared with MWCNT-doped nanocomposites due to a lower UV light shielding effect. This phenomenon also justifies the decrease of nanocomposite Tg with the increase of CNT content in every case. The electromechanical analysis reveals that SWCNT- and DWCNT-doped nanocomposites show a higher electromechanical performance than nanocomposites doped with MWCNTs, with a slight increment of strain sensitivity in tensile conditions, but also a significant strain sensitivity gain at bending conditions.
