- Instead of wheeling around, the 5kg Hedgehog "hops and tumbles" around microgravity environments. These bots can handle a variety of surfaces, including those covered in rocks or ice.
- One Hedgehog prototype has 8 spikes and 3 flywheels. The spikes can "pop" the bot in a direction, and the flywheel can roll it where it needs to go.
- One problem: these bots aren't autonomous yet, but they are cheaper than a traditional rover. The next step is to increase how much the hedgehog can do without instructions from earth.
