Swarms of robotic unicycles may deliver packages in the future
The Transwheel drone has robotic arms (pictured) which it can use to pick up and place down parcels. It would use facial recognition to confirm the identity of a recipient when delivering an item under the vision outlined by designer Kobi Shikar
DARPA & Boston Dynamics have created Legged Squad Support System (LS3); designed to help soldiers carry their gear in the field in terrain where wheeled vehicles just won’t cut it. Basically, it’s like a robotic donkey, can carry 400 pounds of equipment & works autonomously, obeying simple spoken orders.
