“…With the development of robotics, the contact process control between robot end-effector and the environment is becoming an important part of robotic applications involving, surface handling (such as polishing (Cao et al , 2020; Kana et al , 2021; Lakshminarayanan et al , 2021; Ochoa and Cortesao, 2021), medical rehabilitation physiotherapy (Ajani and Assal, 2020; Hasanzadeh Fereydooni et al , 2020; Zhang et al , 2020; Ajani and Assal, 2021) and physical human–robot interaction (Keemink et al , 2018; Ferraguti et al , 2019; Mustafa Can Bingol and Aydogmus, 2020b; Mustafa Can Bingol and Aydogmus, 2020a; Sharifi et al , 2021). The main problem of contact establishment involves the scale of contact force, which may reach prohibitive value, which may directly lead to mission failure or even more serious consequences.…”
