The performance of robot actuators is still primarily evaluated using manufacturer-provided static specifications such as maximum torque and rated speed. However, these metrics are insufficient for assessing dynamic behaviors that are essential for physical interaction, including backdrivability, tr…
Although existing Sparsely Annotated Object Detection (SAOD) approches have made progress in handling sparsely annotated environments in multispectral domain, where only some pedestrians are annotated, they still have the following limitations: (i) they lack considerations for improving the quality…
Legged robots have opened their way to more stable and practical mobile robot applications. However, their locomotion strategies are limited to similar patterns, and dynamic running at high speed still is not successfully realized. One of the key technology required for the realization of the dynami…
It is necessary for a robotic leg to behave like a spring to realize a periodic hopping, since it can be efficient and does not require complicated control algorithm. However, the impact force makes the realization of periodic hopping more challenging. In this letter, an optimal landing strategy for
In this paper, Dynamic Dumbbell, a novel robotic device for advanced muscular exercise of upper limb is presented. The type of exercise load is classified and designed in terms of mechanical engineering to be implemented in Dynamic Dumbbell. The exercise load model, which is named as programmable ex…
This letter presents an enhanced external torque estimation algorithm for series elastic actuators (SEAs) expanding the usability of the residual-based technique. Although the residual method demonstrates online torque estimation capability in diverse applications and thus becomes popular, it is pra
In this paper, elastically actuated bi-articular manipulator is developed using a novel compact planetary geared elastic actuator. The newly developed SEA, which is compact and has little backlash, can achieve high force control performance. The configuration of the developed manipulator is designed…
The tension control of wires can benefit from Series Elastic Actuator (SEA), which is a potential emerging actuator system. In this paper, it is verified that the tension of wires can be successfully controlled by a novel SEA, called Compact Planetary-geared Elastic Actuator (cPEA), which incorporat…
