LS3-B and LS20-B SCARA robots from Epson features batteryless encoder, lower cable duct profile for hard to reach work cell layouts, built-in camera cable for a simpler vision system setup, and new top-of-arm layout for an enhanced equipment mounting process. The LS20-B has a 20 kg payload and available reach of 800mm and 1000mm, making it ideal for higher payload applications, while the LS3-B SCARA robot has a payload of 3kg and a 400mm reach. Both robots include Epson proprietary Quartz MEMS technology, a hardware and software system that combines force feedback and position for improved servo performance and are compatible with the new RC90-B controller, a single controller with wiring options for both PNP and NPN.
