Angle assessment for upper limb rehabilitation: a novel light detection and ran...
Klein, Luan C.; Chellal, Arezki Abderrahim; Grilo, Vinicius F.S.B.; Braun, João; Gonçalves, José; Pacheco, Maria F.; Fernandes, Florbela P.The accurate measurement of joint angles during patient rehabilitation is crucial for informed decision making by physiotherapists. Presently, visual inspection stands as one of the prevalent methods for angle assessment. Although it could appear the most straightforward way to assess the angles, it presents a problem related to the high susceptibility to error in the angle estimation. In light of this, this st...
Retrofitting industrial robotics: an embedded system approach to controller enh...
Grilo, Vinicius F.S.B.The increase in productivity and efficiency caused by the presence of robots in industries and in automation processes, whether they are mobile robots or manipulator robots, encourages research and makes the area of robotics widely studied in academic scope around the world. The development methodology began with a study of the functioning of the internal modules of the original FANUC RJ Controller model, inclu...
Development of a Low-Cost 3D Mapping Technology with 2D LIDAR for Path Planning...
Ferreira, Edilson Santos; Grilo, Vinicius F.S.B.; Braun, João; Santos, Murillo F. dos; Pereira, Ana I.; Costa, Paulo Gomes da; Lima, JoséThis article presents the development of a low-cost 3D mapping technology for trajectory planning using a 2D LiDAR and a stepper motor. The research covers the design and implementation of a circuit board to connect and control all components, including the LiDAR and motor. In addition, a 3D printed support structure was developed to connect the LiDAR to the motor shaft. System data acquisition and processing a...
Assessing the Reliability of AI-Based Angle Detection for Shoulder and Elbow Re...
Klein, Luan C.; Chellal, Arezki Abderrahim; Grilo, Vinicius F.S.B.; Gonçalves, José; Pacheco, Maria F.; Fernandes, Florbela P.; Monteiro, Fernando C.Angle assessment is crucial in rehabilitation and significantly influences physiotherapists’ decision-making. Although visual inspection is commonly used, it is known to be approximate. This work aims to be a preliminary study about using the AI image-based to assess upper limb joint angles. Two main frameworks were evaluated: MediaPipe and Yolo v7. The study was performed with 28 participants performing four u...

Braun, João; Baidi, Kaïs; Bonzatto, Luciano; Berger, Guido; Pinto, Milena F.; Kalbermatter, Rebeca B.; Klein, Luan C.; Grilo, Vinicius F.S.B.Robotics competitions are highly strategic tools to engage and motivate students, cultivating their curiosity and enthusiasm for technology and robotics. These competitions encompass various disciplines, such as programming, electronics, control systems, and prototyping, often beginning with developing a mobile platform. This paper focuses on designing and implementing an omnidirectional mecanum platform, encom...
Impact of EMG Signal Filters on Machine Learning Model Training: A Comparison w...
Barbosa, Ana Carolina; Ferreira, Edilson Santos; Grilo, Vinicius F.S.B.; Mattos, Laercio; Lima, JoséOur current society faces challenges in integrating individuals with disabilities, making this process difficult and painful. People with disabilities (PwD) are often mistakenly considered incapable due to the difficulties they face in daily tasks due to the lack of adapted means and tools. In this context, assistive technologies play a crucial role in improving the quality of life for these individuals. Howeve...
