  The independently steered wheels seem to be working well. What are you planning for your digging system?

• 
  @isopod002 ай бұрын

  We are currently finishing the manufacturing of our digging system. It will be on a lift that lowers it into the ground for digging and then raises it up out of the ground to be in a position for dumping. It will have a thin steel wedge for digging and a conveyor belt for dumping the material out of the other side of the robot. Stay tuned for more info!

  How does the shooter work without going to one side

• 
  @isopod004 ай бұрын

  Our shots do tend to drift to the side a bit, it's not too bad but I would probably recommend using two shooter wheels to counteract spin on the ring versus one like we have here

•

  We built ours with only one and its not powerful enough and it turns too much. How did you get it to drift so little though. Also what motor are you guys using

  @@Sokara7 We used a NEO motor for our shooter, I believe with a 1:1 gear ratio (no reduction). Although, I would probably recommend having two shooter wheels, one on each side, each powered by a NEO (or similar) motor

• 
  @jaredschultz18675 ай бұрын

  there are quite a few improvements I can see right off the top: 1 improve climber, it was put on during the last hour and is not optimized, it needs counter weight due to its positioning, and the travel distance should be tweaked, 2 the flywheel made the note spin off to the side, so some way to center the shot would be ideal (add a second wheel either on the other side, or like the kit of parts bot), 3 make the pneumatic ramp also function as a player station intake, 4 add another row of rollers to intake so it can intake from both directions (explained better in another comment)

  What happens if you drive over the note backwards, does it still pick up the note, or just push it along?

• 
  @jaredschultz18675 ай бұрын

  We never tested this however I see two outcomes: it just gets pushed and it just stays under the bot, or the bottom intake wheel (two inch compliant) would pull it under the bot (could damage the element) spitting it out in front where we could intake it normally. The main shooter plate extends down to almost touch that bottom row of wheels so there wouldn't be any way (without modification) that it could intake from that direction, that said by adding another row of rollers (mirror the top row of intake wheels) it may become possible to intake from both directions

• 
  @richardtopolewski5555 ай бұрын

  @@jaredschultz1867 If when it spits it out in front, depending on lots of factors (e.g. speed of surface of the wheels -- smaller wheels should be going slower then surface of larger/higher wheels -- and how grippy they are relative to the carpet, and how fast the robot is going), it seems if the larger/higher wheels grab it, it may just get picked up, which would be super cool and useful.

  Top of bumpers can be 7.5 inches off the ground, bumpers can be a minimum of 5 inches. That gives you 2.5 inch clearance for a 2 inch game piece.

  Unfortunately not possible because although we can build a robot in 3 days that is capable of doing the different parts of the game, making that robot robust and reliable is a challenge that takes plenty of time, which we didn't have. There were plenty of bloopers of the extender falling apart and claw failing to get a game peice where it needed to go that were cut out as the main purpose is to show the constructed ideas for other teams to iterate on if they want to. I beleive some of the issues faced and how they could be improved will be talked about in the robot walkthrough that'll be posted today, but in short the robot wasn't able to cycle in the time we had to film and check for issues.
