Q/A General - Could we drill holes in the table to mount our robot arm and sensors? No, you are not allowed to drill holes or modify the table in any perminent way. Logistics track: - Where can I find the bar code sample file http://rpal.cse.usf.edu/competition_iros2019/bar_code.txt - Could you provide us with the bar code scanner model number, so we can purchase it for practice? You can bring your own bar code scanner. - If we are allowed not to use provided scanner, can we use camera instead of scanner to read data from bar-code? Yes. - What kind of the bar-code will be used? (For example, EAN or Code39 or NW) EAN - Is it allowed to use a camera + image processing to perform bar code reading? Or is it required to use a commercial laser-based scanner? Allowed - Could you provide us with the bar code scanner model number, so we can purchase it for practice? You can bring your own bar code scanner.  So any scanner will fine. If you don't have one,  please let me know. -What are the rules on re-grasping for the logistics track? Is it allowed to re-grasp an object after picking it up from the bin? For example, placing it on a table surface for easier bar code scanning. Allowed.  - Will there be any object available for the logistics track? Or will they only be available on the 4th of November? The objects will be provided to you on Nov. 3rd. For your practice before that day, we provide pictures so that you can purchase similar object locally. - Could we use the bins bring by ourselves? No. - If not, could we get the specification of the table and bins to facilitate our hardware design? Bin demension is 600x400x300mm (LxWxD). The table's lxwxh is in the Competition Instruction file. You can bring your own stands and extra tables and other setups. - Can a team manually clear the bin after they decide to give up the current batch? Yes. - Can there any adjustment made between the batches? No coding change. If something moves, you can recover. But, you cannot change the setup. - Can robot grasp more than one items at a time and scan them one by one Yes. - Are the exact items in the releases pictures will be in the competition? Maybe not due to availability. But they will be similar in appearances. - What kind of scanner will ber provided? You can bring your own scanner. - Can the scanner mounted on the table? Yes. - How to use the bar code? Please refer to http://rpal.cse.usf.edu/competition_iros2019/bar_code.txt Manufacturing track: Joe Falco will host q/a sessions. Service - "The to-go cups are loosely nested together in one pile." Does that mean they are stacked but not stuck? Yes. - "But, there is no refill of any items or water. " This expression is not clear very clear to me. No extra spoon, water bottle, ice cubes, etc to be added. - Can contestants decide the position of predefined tools? (Inside the 30cm * 30cm work area or outside) The locations could be predefined. But they are not fixed or glued to the table. No marking is allowed. - Whether the robot is allowed to put the spoon on the predefined tools in step2? According to the description -- "The team will win 10 points if the robot can pick out a teaspoon from the tray. The team can forfeit the 10 points by hand the spoon over to the robot," you can manually put the spoon on the predefined tools and give up the 10 points. No manual tool changing is allowed. - The defined location in step8 is inside the work area or outside the work area? Inside. - What is the height of the table at the time of the service-robotic track? The wxlxh of the table is in the Competition Instruction file.
