Hi. Welcome to the Stretch Forum!
A docking station is definitely on our radar. We’ve heard now from a few Stretch users that it would be useful. We currently have a conceptual design for a simple add-on to the Stretch trunk and a base station that would allow auto-docking to the existing NOCO charger.
If there’s interest in the Stretch community we could put some engineering resources on this and develop the concept. Presuming it all works as intended, we would likely release the add-on on the Stretch Tool Share along with some demo code for auto-docking under Stretch ROS.
I’d expect the initial release would be fairly ‘beta’ but we would welcome feedback and contributions from early adopters to help us iterate and improve it.
