The Raptor walking robot, developed by researchers at the Korea Advanced Institute of Science and Technology (KAIST) can run at up to 46 km/h. He is therefore the fastest two-legged walking robot in the world. The robot design was based on the model of a velociraptor dinosaur. Raptor is just under 50 centimeters in height and weighs just 3 kilograms. He can balance himself and jump over obstacles of up to 10 centimeters in height with ease. Each leg of the robot is driven by a brushless maxon motor. The drive systems consist of a high-performance EC-4pole 30, combined with a planetary gearhead GP 32 HP and an MR encoder. The controller consists of a maxon ESCON module 50/5. The robot was developed by Prof. SooHyun Kim, Prof. KyungSoo Kim, Prof. Daigil Lee, Dr. JongWon Park, Jinyi Lee and Jinwoo Lee.
maxon motor introduces the world's first steam sterilizable encoder ENX EASY. It is available in an incremental (1024 counts) and an absolute version (4096 steps) for diameters of 13 and 16 mm and is designed for 1000 autoclave cycles. The encoder can be integrated into the brushless drives ECX 13 and ECX 16 SPEED without increasing the length. When the gearheads GPX 13 and GPX 16 SPEED are added to the combination, engineers receive a fully sterilizable positioning system.
