“…Conditionally active elbow orthosis can be divided into three parts: mechatronic, which controls and includes an actuator; mechanical, which is considered in this article, which is responsible for the transmission of motion and the body in which all structural elements are mounted, which is directly attached to the patient's hand. In the role of an actuator in active elbow orthoses, a stepper motor [4] is used, and such devices are usually controlled using EMG sensors [5], which measure the activity of signals generated by muscles. An Arduino Uno microcontroller will be used for signal processing.…”

Rehabilitation of patients should not be limited only to the time of intensive treatment in the hospital, but also to therapy in the following stages, especially during daily activities, if the patient’s condition requires it. Such devices that help the patient during postoperative or post-traumatic rehabilitation after joint damage are orthoses. This paper provides an overview of various types of orthoses, selects material for structural elements of the orthosis, and determines the stress-strain state of the sample under study. Also, based on the necessary operating conditions, the engine and bevel gear are selected. The model of the orthosis prototype is presented and the stress-strain state of the structural elements of the elbow orthosis prototype is determined.

“…The orthosis of the elbow joint can be conventionally divided into several parts: the mechatronic one, which controls and includes the actuator, the mechanical one, which is considered in this article, which is responsible for the transmission of motion, and the body, in which all structural elements are mounted, which is directly attached to the patient's hand. A compact motor [1] is used as an actuator in active elbow orthoses, and such devices are usually controlled using EMG sensors [2] that measure the activity of signals generated by muscles.…”

Over the past two decades, upper limb exoskeletons used for service delivery and rehabilitation have attracted attention from the biomedical and engineering sectors. Technology is becoming one of the key solutions for physically weak or disabled people. Mechanical devices were developed to improve the performance and strength of the user. Devices that help the patient during postoperative or post-traumatic rehabilitation after joint damage of various types are orthoses. There are different types of orthoses, such as mechanical, active with EMG functions, exoskeletons, and others. In this work, an overview of various types of orthoses is given, problems of fixing orthoses elements are considered. In the review of the literature related to these studies, the advantages and disadvantages of bolted connections are given. Two contact problems of the orthosis were also considered and the stress-strain state of the bolted joint of the structural elements of the elbow orthosis prototype under study was determined using the FEMAP with NASTRAN software package. Based on the necessary operating conditions, a prototype model of the orthosis was presented.

In the field of robotics, sensors are crucial in enabling the interaction between robots and their users. To ensure this interaction, sensors mainly measure the user’s strength, and based on this, wearable robots are controlled. In this paper, we propose a novel three-axis force/torque sensor for wearable robots that is compact and has a high load capacity. The bolt and nut combination of the proposed sensor is designed to measure high-load weights, and the simple structure of this combination allows the sensor to be compact and light. Additionally, to measure the three-axis force/torque, we design three capacitance-sensing cells. These cells are arranged in parallel to measure the difference in capacitance between the positive and negative electrodes. From the capacitance change measured by these sensing cells, force/torque information is converted through deep neural network calibration. The sensing point can also be confirmed using the geometric and kinematic relation of the sensor. The proposed sensor is manufactured through a simple and inexpensive process using cheap and simply structured components. The performance of the sensor, such as its repeatability and capacity, is evaluated using several experimental setups. In addition, the sensor is applied to a wearable robot to measure the force of an artificial muscle.
