After discussion with the rest of the NIST team we would like to clarify the way in which dexterity-strength is being scored.
The primary metric is completeness. For a given board position, all 5 motions (pick up, put down to one side, put down to the other side, carry out, place into crate) need to be completed.
The total score will be the sum of the weight (in kg) that you get into the crate at the end, after completing all 5 motions, for every position. So for instance if your scoresheet looks like this:
5 kg at ground, white
2 kg at ground, yellow
1 kg at ground, orange
2 kg at 30 cm, white
1 kg at 60 cm, white
Your total score will be 11. The idea is that if you’re able to perform the task across more of the reach space, you have more points available to you. Of course we fully realise you won’t be at whole numbers of kilograms here.
Also note that we are testing per configuration. So while it may be an advantage to, say, lock out your weakest joint which will reduce your reach space but greatly increase your strength for the places you can reach, this will now be a different configuration and will need to go through the other dexterity tests separately. To get a good overall score, it is still an advantage to maximise dexterity (which accounts for 2/3 of the available tests).
Note that on the online form (or spreadsheet) you will be reporting per position so this doesn’t change how you run or report.
Please let us know if you have any questions!
