[Grappling Hook/Tether]

This would be very useful if you were to build rovers 

[Wheel attachments for the motorized hinge]

Title says it all, i would like to see wheel attachments for the motorized hinge, basically a round hollow block of various sizes that fits around a hinge with high friction so that it can get good grip on the ground

I've built rovers around a year ago and I had to use thrusters arranged in a specific order for it to be round enough to roll well 

Thanks for taking your time to read this post
