This special robot can use it's shell-like body shape to move through tiny gaps.
It's based on a species of cockroach that lives in tropical rainforests.
The insects have to cross over grass, shrubs, leaf litter, tree trunks and fungi.
The robot's streamlined shell can perform a roll to help it slip sideways through obstacles without needing extra sensors or motors.
The makers hope it can be used to make new robots for search and rescue operations in hard to reach areas.
Researchers used high speed cameras to study the movement of the robot cockroach through a man made obstacle course filled with grass-like vertical beams with small spaces in between.
