Future robots are expected to share the same workspace with humans and work in cooperation with them to improve productivity and maintain the quality of products. Considering this situation, we have developed a novel assembly task co-worker robot to support workers in their task by delivering the parts and tools to workers. Although such systems have improved work efficiency by predicting human's...
This paper proposes a co-worker in-time Parts/tools Delivery to You robot, PaDY, in an automobile assembly line. Since co-worker robots share a workspace, the workers are at risk of colliding with them. Therefore, the safety of the workers has to be considered when operating such robots. In previous studies, the robot generally stops to ensure the worker's safety when a collision is detected, delaying...
We propose a trajectory tracking control algorithm for a vehicle with a large sideslip angle. The proposed algorithm was designed on the basis of a vehicle's planar motion using a four-wheel vehicle model. The proposed algorithm controls the vehicle's position and attitude by integrating the motion control algorithm for a vehicle with a large sideslip angle into the trajectory tracking algorithm for...
A novel human motion estimation method is presented in this paper. The motion of the human is estimated by an Unscented Kalman filter (UKF), in which a nonlinear dynamic model is used to predict trajectory of human. This dynamic model is obtained from sample data by using Gaussian Process (GP) regression. The sample data includes information of body segment posture and trajectory data collected by...
We have developed a novel assembly task partner robot to support workers in their task. This system, PaDY (in-time Parts/tools Delivery to You robot), delivers parts and tools to a worker by recognizing the worker's behavior in the car production line; thus, improving the efficiency of the work by reducing the worker's physical workload for picking parts and tools. For this purpose, it is necessary...
We have been developing a novel human-friendly/cooperative work support robot. This system named PaDY (in-time Parts/tools Delivery to You robot) supports worker by delivering parts and tools to worker based on statistical analysis of the work in an automobile assembly line to reduce the worker's physical workload and improve work efficiency. In this paper, the collision avoidance method based on...
