Today we just finished wiring and plumbing everything. Take a look and enjoy!

Looking good, team 3637.
As a friendly suggestion, make sure your claw isn’t violating rule <R04>, especially the related blue box in the rules:
If the ROBOT includes protrusions that form the “leading edge” of the ROBOT as it drives and are less than 1 sq.in. in surface area, it will invite detailed inspection. For example, forklifts, lifting arms, grapplers. etc. may be carefully inspected for these hazards.
Reasonable efforts must be taken to remove, mitigate, or shield any sharp edges, pinch points, entanglement hazards, projectiles, extreme visual/audio emitters, etc. from the exterior of the ROBOT. All points and corners that would be commonly expected to contact a GAME PIECE should have a minimum radius of 0.125” to avoid becoming a snag/puncture hazard. All edges that would be commonly expected to contact a GAME PIECE should have a minimum radius of 0.030”.
It looks like you guys might be getting close on the minimum radius for the tips of your claws.

Thank you for the reminder! I will check that off tomorrow.

Where are your safety glasses? ::safety:: Especially dangerous when you’re using your claw to put the tube around a person’s head. ::ouch::
Can you floor-load?
Ummm not on our heads? 
We can’t floor load. We aren’t going to drop the tubes from the feeder anyway, so it shouldn’t be an issue.
Ethan
.391" is the smallest radius so we are good 
I like your team name! 
Congratulations on having a working robot about 16 whole days before ship date. Looks like you guys made an awesome, sturdy scissor lift.
Thanks! Yeah we just have to do minibot now. We have a team working on that now, the problem is going to be where we are putting the deployment mechanism.
It ways about 96 pound right now w/o battery or bumpers.
I think minibots don’t count towards the 120 pounds just in case you didn’t know alongside with the battery and bumpers.
Yep We know, we don’t have that completely built yet (I don’t think?). We are going to add some more metal almost like a spoiler look since we really don’t have anywhere where we can put sponsors logos.
Ethan
o my gosh you guys are my heroes…we are never that light, we are usually 122 pounds lmao (ya those holes arent for looks)
Thanks!
We knew we were light when we finished just the scissor part, the holes in the bracket at the bottom are there so we can see into the electronics.
If we have extra room after putting on the minibot deployment system, then we are going to add some bars of metal into it so we can distribute the weight better. We put it on race car scales and the front was 46 pounds and the rear was 50 pounds.
Ethan
I love the robot, but I have to say the shop dog is awesome!
Thanks!
And yeah we all love Otis, he guards our robot. There is a great shot of him laying on his back in front of the robot in today’s post on our website.

what happens when the scissors lock at the bottom-most position? our team is having the locking problem with our scissors.
Lock? It doesn’t lock at the bottom position. The bottom position does however require the most force to get it to go up. How are you making your scissor work?
Ethan
we’re using dual screws (like the ones included in the KOP) to pull the back end of our scissors towards the front using the Fisher Price motor. i’ll take some pictures tomorrow and upload them. i don’t like how the scissors were made on our bot, your team’s bot looks lighter than ours.
Our scissor is very light. The heaviest part is the bottom linkage because they were flexing when they were lighter. We used one ballscrew that was from the KOP and a window motor since those have 1201 oz-in torque. I don’t know what the fischer price motor output is.
the fisher price motor was a poor choice for our scissor lift, but our team is scared of window motors, pneumatics, and anything else i have proved we have the capability to make work…
i’ve been whinking of switching to a larger banesbot motor in out FP gearbox, maybe during the dinner break everyone else takes
