Master-slave robots with transmission of force sensation have gotten a lot of attention in the supporting surgery or searching danger area. The operators feel force sensation acting on slave robots by handling master robots. The transmission is realized by 4ch-bilateral control. In order to put the system into the practical use, bilateral control for multi degrees-of-freedom robots with lightweight...
Many researchers proposed methods to adapt uneven terrain for biped robots. Environmental mode compliance control is one of those methods. Another feature of this control is that it makes a walking stability. However, the environmental mode compliance controller cannot maintain the body horizontally, and cannot be applied if the body is inclined. In this paper, gyroscope integrated environmental mode...
Control for biped robots with toe and heel joints is researched for walking on uneven terrain. In conventional research, a switching impedance controller using rotational torque with the toe and heel joints for adaptation to unknown uneven terrain was proposed. In this research, that controller is modified for the adaptation using vertical reaction force. Additionally, a generation method of force...
This paper describes adapting motion of a biped robot. In some cases that biped robots walk in human environment, the robots encounter non-flat surfaces. To adapt to such environment, it is necessary to get environmental information by sensors. In this paper, the environmental information is transformed into useful structure, defined as ??environmental modes??. The environmental modes consist of four...
This paper describes a biped walking pattern generation by using preview control with virtual plane method. It is important for biped robots to generate desired walking patterns which satisfy given Zero-Moment-Point (ZMP) trajectories. Solving ZMP equation is one of the key issues in the biped walking research field. Many kinds of the solutions have ever been proposed. One of the most efficient solutions...
