Welcome!
We are two students, Popescu Teodora and Precup Cristina who decided it would be fun and useful to build a barman robot. It could be used by anyone who is not able or don't want to pour liquid in their glasses (for example people with disabilities, or at a party when nobody wants to spend time doing this)
Lately, we've made a few adjustments to our design, i.e., we added a side camera and changed the capture angle for the front camera (it is now way above the gripper).
As for the implementation, we switched to colour detection for the bottle due to various reasons.
Progress:
rotate around the table and scan the table for the bottle
set the bottle to the centre of the image and prepare the robot's position for when approaching the bottle (use the side camera)
get close to the bottle and center it. This is crucial to grabbing the bottle with the gripper (use the front camera)
Below is a video that shows how the robot approaches the table by respecting a certain distance, rotates around it and stops when it encounters the bottle within the centre of the image. It then turns around, backs off, and drives back, this time front facing the bottle. The reason for doing so is that otherwise, the robot might hit the bottle with its gripper.
Side note: a more complex video is on its way... In the meantime, enjoy the more artistic side of BarRD:
