GRC-100B is a SCARA robot controller. It integrates NexCOBOT's general robotic control software, NexGRC-SC, to perform real-time robot control and provides  TPUI (Teach Pendant HMI) for TP-100-1 and TP-200 to users directly control their own robot hardware. Besides, NexGRC-SC also provides Windows APIs for users developing their own robot control HMI or application. GRC-100B also provides an integrated development environment called NexMotion Studio to speed up development time for users.
