If you have turned on a light in the summer you might have seen roaches scattering away quickly. We are guessing it’s not really something you appreciate so much, but now roaches could be a little more pleasant to look at. Researchers at the UC Berkeley decided to make a robot roach and they came up with a robot that can run 11 miles per hour by the name of the X2 VelociRoach.

Not only can the X2 VelociRoach run fast, it can also launch other flying robots into the air. The X2 is the follow up to the first VelociRoach built by the researchers which could run up to 7mph. The researchers did try to give it more speed but when they took it up to 11 mph by giving it more than 45 strides each second, the robot began to fall apart.
The X2 VelociRoach was given a new body and fiberglass legs instead of the rubber ones it previously had. In order to give it flexible joints, Kevlar was used but this was too weak, despite the fact that it is well known for its ability to stop bullets. The researchers then turned to using nylon.
The robot is now able to run at speeds of up to 11 miles an hour and this means that it is the fastest bug sized robot in the world. The researchers said it is “the highest frequency the robot could use without losing appendages.” It has a design that is so fast that it really tests the materials limits that are holding it together.
Now that that they have the X2 VelociRoach the designers are using their first design to launch a robot bird into the air. Well what better use could there be?
