I’ll post a short picture and description of our robot if no one else on my team gets to it first, but viewers of this thread may wish to know that I’m making a little “scouting book” for Newton teams that has 6 robot pictures, team names, and the event that the robot did best in on a page, that I’ll be putting up in PDF form soon. Assuming I get it done, I’m like 20 bots in
Anyone from my team feel free to add to or correct this; I know less about the technical aspects of the robot and more about what it can do on the field.
Team 1714 More Robotics
Bot Name: I don’t think anyone is really sure. It was “Philbert 2” until we thought of a name, then it was “Dean Kamen” when he signed the side of it. Now that Woodie Flowers signed the other side, I don’t know.
Drivetrain: 4 Wheel, wide. Back wheels driven by CIMs and bear most of the weight, the front motors are driven by geared-up window motors and break loose during turns for better steering. Powerful enough to push robots around easily.
Manipulator: Fast clear polyurethane belt driven by a CIM for speed. Diverter allows for storing of 3 balls in the front (we can thus hold the empty cell and fire at the same time, or just hold more moon rocks). Simple CIM-driven shooter mounted onto self-lubricating acrylic turret (180 degree range of motion). Feeds 6 balls out in under a second, 9 balls (capacity) in about 1.75 seconds. Wide ball collector doesn’t jam often and reverses to unjam very quickly (we have never had our manipulator stuck for more than a second). Our shooter manually aims and dumps out from short distances very accurately.
Chassis: 100% polycarbonate, as always
From a strategy perspective, the main advantage of our robot is our quick, accurate dumps. Other bots have us beat on capacity, but we can slam up on someone, unload, and drive away before you have time to react. We also load very quickly, as the belts don’t have to deliver up to a storage container (the belts ARE the storage), and can pick up Empty Cells off the ground without firing them.
]Team 1730 – Team Driven]Drive Train: Four wheels. Unique drive train with a toggle between crab and swerve drive. We utilized the Jaguars for four wheel drive. The front most wheels are steered together, as are the back wheels. Traction control guarantees maximum acceleration. With its ability to strafe, crab, four wheel steer or execute zero point turns, this robot is very difficult to score on or pin.]Elevator: Using surgical tubing and a CIM motor, we made a compression elevator that will collect balls two wide and funnel to one. The elevator is reversible. We will usually store an empty cell in our elevator for the empty cell. This elevator is very fast, i.e. - collection time from the floor to the hopper is less than half a second.) ]Turret: The turret is capable of 270° of rotation. There is also a mixer (in the bottom of the turret) that is constantly spinning to keep free of all jams, and push the balls into the shooting device. The shooter consists of two horizontal rollers that are powered by a CIM motor. The shooter has variable speeds, making it an efficient shooter from point blank to six feet. It will unload its 11-ball payload in about 3.2 seconds. With the turret we can also score on ourselves in the event that we’re close to doubling the opponents score.]Autonomous: Defensive. The robot will travel forward, spin either 90° or 135° (depending on whether we’re in the middle or on the end) and back up into our own alliance’s area. This uses our robot as a shield to block the human player’s shots into our trailer.]Strategy: We are a great all around robot. Our main focus is the super cell. In terms of empty cells, we always deliver a minimum of two and can get four depending on the needs of the alliance. As we make our way to the out post and back, we will collect moon rocks and store them in our hopper or give them to the human player. With our turret, we perform what we like to call drive bys, where we will keep on our merry way and still score. *]Human Player: Our human player will make 70-80% of his shots at a decent range, and at close range, it’s lights out. He has been clutch scoring the much-needed super cells round after round with just seconds to spare. He waits for an opportune time and does not waste one moon rock or super cell.
Soo… I have to be honest, I’m only posting what I was told to post… I’ve not spent enough time around the technical side robot this year to know anything up close. However, feel free to PM with any questions and I’ll find out for you.
292 PantherTech
Regional winner at Boilermaker
4 Wheel Drive
can play offense or defense
can pick up off floor or human load
can get empty cell off floor or through the hole
we can unload moon rocks at three levels
note we have made modifications since winning the NASA/VCU regional
drive train: 4 wheel drive, chain driven from one cim and a modded toughbox per side. speed is around 8 f/s
capacity: in the belt and under the bot we can hold between 7-10 balls plus another 3-4 balls in our newly added dumper.floor pick up
scoring: we have done away with our long range scoring tri shooter and replaced it with a front facing basket. we will use the basket for delivering empty cells but it is capable of scoring on trailors. our primary scoring mode is our “puke mode” where we empty our full load at point blank range. we’re capable of scoring 20+ points in a match but can do anythin our alliance needs (empty cells, defense, ect…)
autonomous: we have multiple autonomous modes capable of running from any starting position. our primary mode drives by our out post and pics up an empty cell.
For those of you interested, there are a few videos posted on YouTube of MOJO in action at the Cleveland Regional. Search on “Cleveland Regional” and they’ll come up. Don’t ignore the Chicken Dance Video, that is probably the most revealing of them all.
Like many of you, we’ve been practicing our driving in an attempt to improve on our performance. We also plan a couple of minor upgrades that we hope will also make an improvement in our performance.
Our hopper holds 20+ moon rocks and we can empty it in less than 3.5 seconds by raising the floor with a lead screw that is powered by a CIM motor. Our acquistion is also powered by a CIM and consists of a conveyor belt that contacts the game piece near the front of the machine and pulls them up and deposits them into the hopper. We designed the machine to be able to load from the top or the floor. We did not use the top loading and plan to sacrifice that capability to upgrade our unloading accuracy. We have four wheels driven by two CIM motors (one on each side). We use a rotary bar with vinyl “fingers” powered by a FP motor using the AM planetary gear box.
We can handle empty cells by either sweeping them into the hopper and dumping them at the refueling station or by drawing them into the conveyor system and then reversing the motor to discharge them into the refueling station.
Our Payload specialist was pretty accurate in Cleveland and the various published data based on the different algorithms are pretty close to our demonstrated capability. Our own scouting data shows that we averaged 10 moon rocks scored by the machine per match.
Our robot’s name is Otis. It has 4 wheels. It can hold up to 25 balls. It is a dumper with a platform that raises up. At the last competition, our human player made 80-90% of the shots. We won the West Michigan District event.
Hey everyone, I was wondering if I can get some help with scouting, I would prefer some tips with paper and pencil and some with software. What software do you find is the best.
Thank You

I use the GUSS scouting system. It is really a great tool. It’s incredibly accurate at predicting match victories, which is just insane. Get it <HERE>](http://www.chiefdelphi.com/media/papers/2214) If you want some tips and tricks with the pen and paper side, come on over to 1730’s pit or find us in the stands. We would be glad to help in any way possible. I will be in the pits most of the time and my Number 1 will be in the stands taking care of the matches. I’m sure we can get you up and running in no time.
Hey Tyler - we are pretty fond of 1511’s scouting system. http://www.chiefdelphi.com/forums/showthread.php?t=75264 It’s very detailed and keeps our team busy! You can come check it out in the stands and even lend a hand for a few matches if you want! We will share the data if you want to compare it to some other scouting results!
