Therefore, children’s products are needed by more and more families. For the only child in the family, parents want them to live more comfortably, investing a lot in children’s living goods.
Furthermore, the types of products in the children’s consumption market are increasing, and children’s consumption level is rising. With the continuous improvement of people’s living standards all over the world, the children’s consumption market is developing in a rising trend. With the increasing demand for baby chairs in the global children’s consumption market, we believe that the methodology proposed in this paper will attract more research and industry interest. The experimental results demonstrate that our controller can achieve satisfactory performance by controlling the position error in a reasonable range and keeping the manipulation stable and smooth. The feasibility of both the chair design and its control is verified in the MATLAB simulation environment through reference tracking tasks. Both target posture control and periodic control of the chair are implemented to meet different practical requirements. Moreover, a Cartesian impedance controller enhanced by a radial basis function neural network (RBFNN) is proposed to achieve a safe, smooth and accurate control of the baby chair with children sitting on it in various uncertain situations using integrated actuators. Flexible materials are chosen to adapt to different body shapes for the sake of safety and comfortableness.
Firstly, a novel modularization design method is introduced to redesign the shape and structure of the baby chair to cater to multifunctional demands. Therefore, in this paper, to provide competent assistance to parents in taking care of their children, we propose a novel design and control scheme for improving children’s living goods and easing parents’ burden.
As a human-robot interface, the features of baby chairs, such as their flexibility, comfortableness, safety, etc., are important factors that should be considered. The design and control of baby chairs have attracted great interest due to children’s increasing consumption market.
