As far as I can recall, they use constant voltage instead of constant current and by that they don't force the motor into the new position but rather "suggest" a new position. In the end, they drive a stepper motor very similar to a BLDC or synchronous motor I think. Here is a video explaining it in...

Just because it kinda fits here, may I suggest the new stepper driver IC called TMC2130 from Trinamics? It is really cheap and available on breakout boards with most of the necessary components. We are planning to use it in the next season (however, not for moving our robot) and it is also used in t...

The way I see it, even with all the elements on the team's side, there are too many for the balance (6 max) and the accelerator (10 max). So you have to drop them off on the periodic table and "only" get 5 points for each atom. So I think there aren't many reasons for teams to grab the atoms from th...

+1 for your suggestion of precise positioning. I also especially like the idea, that the robot has to make the decision if the Goldenium is needed in the scale or not. Very nice. I would love to see this change in the final rules. Translated with deepl.com/translator: +1 pour votre suggestion de pos...

Just for your information, I calculated the diameter that needs to be cut out to achieve the weights of 60 g (red) and 120 g (green). For 60 g the cutout needs to be 61,1 mm in diameter (almost all of the puck essentially) and for 120 g the cutout is 41,2 mm big. We tried a hole saw with 44 mm diame...

We are interested in this topic as well. Will it be mandatory for international teams to be there on Thursday morning already? Could you please provide a schedule for the event? It will depend on the schedule on which day we will travel, resulting in much higher hotel costs for all our members, if w...
