The idea is that the robot has a behavior built in that, if enabled, would enable the Vector to understand when it has its path blocked and rather than turning around, it would allow the Vector to lower its Lift, rotate 180 degrees, and rehitch to the cart, and continue on its path. So the robot would rotate but the cart would not.
This would give us two way streets in narrow aisles without having to rotate the entire cart.
This approach would be another way to solve for the idea described in LSA-I-247 (the Flip Ends behaviour within the robot's nav stack).
This idea is also related to the recommendation to make cart markers at both ends of the cart a standard feature.
The attached video shows what this would look like in concept. Note that the video shows an open loop direciton change because the cart only has markers at one end. For more reliable rotating, the cart should have markers at both ends.
Problem/opportunity trying to be solved
Vector+Lift needs wide aisles when hitched to a cart, or the traffic of bots and mhe needs to be limited to one way travel. |

Quantify the problem/opportunity
facilities with narrow aisles and Vectors with Carts |
|
What is the root cause of the problem/opportunity
When Vector is hitched to a cart, the hypotenuse of the cart is the footprint of the robot, if it's required that the robots be able to turn around in aisles. |
