Robotic Exoskeleton Exo-H3

The Exo-H3 is the latest version of Technaid’s lower limbs robotic exoskeleton. This new version incorporates several improvements and is now more versatile, robust and reliable for your research. Among these improvements we can mention:

– Security mechanisms as power shut-off button and mechanical stops.
– Wider area for hips attachment
– Wider mobility ranges for a more human like performance
– Better electronic integration for an improved form factor
– Redesign of connectors for a faster connection.

Exo-H3 emulates the process of human walking replicating a pre-defined gait pattern through six actuated joints in the sagittal plane. Thus, it can assist people that have partially lost the ability to walk after suffering a stroke, contributing to the current neurorehabilitation research

Because it has been specifically designed for research, it allows the implementation of own algorithms as well as the application of different robotic control strategies. This, together with its ability to adapt to different sizes, provides a wide range of possibilities when carrying out research.

For example, the Exo-H3 could be equipped with an on-board computer to interface between the internal Main Controller and a ROS (Robot Operating System) network.

The Exo-H3 also has an Android app as interface to operate the basic functions of the exoskeleton such us gait speed, motor assistance or stand up and sit down commands.
