Welcome to the Multi-Scale Robotics & Automation Lab (MSRAL) located in the School of Mechanical Engineering at Purdue University. The MSRAL performs cutting-edge research on robotic and automation systems at various length scales: macro-scale (cm to m), meso-scale (~100’s of μm to a few mm’s), micro-scale (10’s of μm to 100’s of μm), and nano-scale (nm). Research areas of focus are multi-scale robotic manipulation, automation, and assembly, mobile micro/nano robotics, micro/nano aerial and ground vehicle design & control, medical robotics and devices, MEMS device design and fabrication to aid in robotics and automation tasks, automation for the life sciences, mechatronics, and robotic system integration.
