Abstract— Legged robots have been highlighted as promising
mobile platforms for disaster response and rescue scenarios because of their rough terrain locomotion capability. In
cluttered environments, small robots are desirable as they
can maneuver through small gaps, narrow paths, or tunnels.
However small robots have their own set of difficulties such as
limited space for sensors, limited obstacle clearance, and scaleddown walking speed. In this paper, we extensively address
these difficulties via effective sensor integration and exploitation
of dynamic locomotion and jumping. We integrate two Intel
RealSense sensors into the MIT Mini-Cheetah, a 0.3 m tall, 9 kg
quadruped robot. Simple and effective filtering and evaluation
algorithms are used for foothold adjustment and obstacle
avoidance. We showcase the exploration of highly irregular
terrain using dynamic trotting and jumping with the smallscale, fully sensorized Mini-Cheetah quadruped robot.
