Meet MARCH II
MARCH II is the second generation of the MARCH exoskeleton designed by our team Project MARCH.
31 highly motivated team members are working together to develop this brand new exoskeleton in just one year.
The exoskeleton MARCH II
MARCH II is an assistive robotic exoskeleton designed by Project MARCH, enabling paraplegics to stand up and move autonomously again. Extensive sensor usage and an advanced control system are used to give full movement control for the user. Custom made electronics, compact joint design, and an intuitive input device form the basis of this innovative exoskeleton.
Compact Joint Design
The human musculoskeletal system is extremely strong and compact by nature. To mimic this, the team designed a new joint using a strain wave gear, which allows us to have a high reduction ratio within a small volume. Together with our custom housing with integrated encoders, the design results in a very compact design, yet strong enough to deliver power for different leg movements.
Intuitive Input Device
To provide the pilot with a safe and reliable walk in the exoskeleton, the team design ed its own input device. The main focus of the input device is to provide more intuitive control for the pilot. The team has designed a crutch handle which has integrated buttons that is able to control the movements of the exoskeleton by switching the movement modus. Furthermore, the input device has a screen built in which is able to provide feedbacks to the user for different modus. Hence, this intuitive input device allows the pilot to have an ultimate control over the exoskeleton.
By designing our own custom electronics we can optimize the dimensions and functionalities. This optimum design allows high efficiency in power consumption and greatly reduces volume and amount of cabling. The exoskeleton carries a fully customized battery pack which can power both the motors and the electronics, leading to a very lightweight power solution that enables full wireless mobility during operation.
