“…The area of haptic feedback research is vast, even when restricted to work related to robots; a cursory search for the phrase "robot haptic feedback" in Google Scholar returns more than 37,500 results. Haptic feedback has been used to control robot arms (e.g., Park & Khatib, 2006), wheelchairs (e.g., Luo, Hu, Chen, & Lin, 1999;Christensen, 2011), rotary cranes (e.g., Takemoto, Yano, Miyoshi, & Terashima, 2004), surgical equipment (e.g., Meijden & Schijven, 2009;Okamura, 2004), and remote mobile platforms (e.g., Lee, Sukhatme, Kim, & Park, 2005;Mullins, Horan, Fielding, & Nahavandi, 2007;Rösch & Schilling, 2002). Research on haptic feedback has included mechanical hardware design (e.g., Cho, Jin, Lee, & Yao, 2010), software algorithms that simulate the feel of textures (e.g., Ruspini, Kolarov, & Khatib, 1997), the use of exoskeletons and virtual fixtures to remotely control robot arms (e.g., Rosenberg, 1995), semiautonomous shared control behaviors, such as artificial force reflection (e.g., Nguyen & Ryu, 2011;Lee et al, 2005), and implementing stable bilateral control systems inspired by physics concepts (e.g., Anderson & Spong, 1989;Niemeyer & Slotine, 1991;Satler, Avizzano, Frisoli, Tripicchio, & Bergamasco, 2009).…”
