Physical Assistive Robots

1. Name: Physical Assistive Robots

 

2. Manufacturer: N/A (Prototype)

 

3. Robot Description: The robot has been developed to assist the user’s walking, sit-to-stand, and stand-to-sit motions. It estimates the user’s state by using a machine learning algorithm and decides on its action based on the result of the estimation.

 

4. Specifications:

4.1 Size and weight:

4.2 Software: SysML is a modeling language, developed for systems engineering based on Unified Modeling Language (UML). SysML is developed to enable experts from different fields who are collaborating on developing a system, such as programmers, designers, electrical engineers, to understand the system.

4.3 Diagrams: Requirement Diagrams, Activity Diagrams, Sequence Diagrams, State Machine Diagrams, Use Case Diagrams, Block Definition Diagrams, Internal Block Diagrams, Parametric Diagrams, and Package Diagrams.

6. Functions and Applications: Robot supports user based on user state estimation.

6.1 If an anomaly is detected, the robot stop action and warn.

6.2 Robot provides information to the user.

6.3 In case of anomaly, the robot asks the user’s intention by button before operating.
