This doesn’t have the flashy futuristic appeal that we’d like to see from high-tech robots, but this amphibious wanderer is well suited for it’s intended purpose. It was developed by researchers at the University of Minnesota to navigate mostly wet environments, collecting data about water quality as part of a distributed army of sensor bots.
The two little arms sticking out in front of it are made of carbon fiber and attached to servo motors inside. The video below the fold shows the trapezoidal body tumbling end-over end to get around. But the awkward, baby-turtle-like locomotion isn’t the only thing in its bag of movement tricks. It can also adjust its buoyancy to float, sink, or hover somewhere in the wet stuff.
To get a better look at what went into developing this, take a look at the Adelopod developed at UMN a couple of years back. We also embedded a video of that tumbling robot because they share the build details we’re always on the lookout for.
