[Zenta's] sphere morphing hexabot, the MorpHex, continues to impress us. He’s just released a video showing it off — by having it roll down a hill!
We’ve been following the MorpHex since 2011, and it really is an amazing project — especially when it started to roll around on its own! In this latest update, [Zenta] was trying to get a good outdoor test video, as he’s never seen a hexapod robot roll down a hill. The video (and rolling) goes smoothly until about 3 minutes 36 seconds in, when the MorpHex experiences a catastrophic inner body servo failure!
Surprisingly, it didn’t fail during its tumble down the hill, but when it was just walking around afterwards. [Zenta] attributes it to a poor quality servo and had bad feelings about it breaking previously. Not fixing it earlier resulted in having to spend 10 hours of his Easter holiday taking Morphex apart and repairing it! Just goes to show… don’t wait until it’s too late to fix something!
And the clip of when the inner body servo fails:
