“…Many have used traditional simulation/cloud framework to attempt robot DT implementations, such as the ones shown in Figure 7 and Figure 8 . Other examples could be found in kinematics [ 232 ], communication [ 233 , 234 ], control [ 235 , 236 , 237 ], planning [ 238 ], and industrial robot energy modeling [ 239 ], in use cases like welding [ 240 ], cleaning [ 241 ], pick-and-place [ 242 ], assembly [ 243 , 244 , 245 , 246 ], manufacturing [ 247 ], warehouse [ 248 , 249 ], maintenance [ 250 ], and construction [ 251 ]. Some well-known robotics simulation tools are Gazebo [ 252 ], MuJoCo [ 253 ], and CoppeliaSim (aka V-REP) [ 254 ].…”
