Flipper Fest 1

Re: Flipper Fest 1

Only one thing that puzzles me, the spining bar dissapears almost halfway into the robot, so how is all the other stuff fitted in that frame? Because you can't place your ram in the way of the spinner.

Very interesting point, I'll have a look at that.

I'll try Wedga Triton instead, please. Stats here: http://strickenone.proboards.com/index. ... age=1#2074

Wedga Triton looks okay. It is in.

Re: Flipper Fest 1

I found some stats on thunderstorm but it says height 9cm. That can't be right, a CO2 bottle is higher than that.

Re: Flipper Fest 1

Can I reserve a spot, should be able to have an entry ready in the next 24hrs

Re: Flipper Fest 1

It's rough around the edges, but I'm sure it should fit in the weight limits and laws of physics

I present, Profanity

Name: Profanity
Weight: 100kgs
Shape: Box shaped, 60 degree angled front with the corners angled similar to Storm 2, 30 degree angled sides and back. I can provide a drawing if needed.
Colour: Black with two yellow speed strips. Fancy, I know!
Speed: 10mph
Length: 800mm
Width: 650mm
Height: 200mm
Drive: 2x LEM130 motors on 33.3v, geared 8:1 driving 4 200mm diameter, 50mm wide urethane coated wheels.
Batteries: 6x 10 cell A123 Packs. 33v @ 13.8AH
Ground Clearance: 0mm @ front wedge, 5mm around sides and back.
Armour: 5mm Hardox 500
Weapons: The weapon is a 4-bar flipper/launch designed very similar to Ziggy and Biohazard, however the big difference is the weapons power source. A 10KG, 500mm diameter flywheel rotates @ 5000rpm storing kinetic energy. The flywheel has a 150rpm/v 300mm diameter brushless motor built into it, rated for 5Kw and 25Nm. The energy is directed to the 4-bar mechanism by a 10:1 plantary gearbox, which drives a crank arm and conrod directly to the 4-bar mechanism. The 10:1 gearbox is connected to the crank via an electro magnetic clutch. This should drive the flipper through it's full stroke
Notes: On the bottom of the flywheel is a vacuum impeller which sucks air from under the robot. A rubber seal running around a 500mm x 500mm square section under the robots base plate provides a seal for the vacuum system, where it provides a suction of 5psi, providing 800Kg*** of down force. This is designed to give the robot ultimate levels of traction and make it hard to flip.

** might not be accurate, need to run it through the calculator
*** rough calculation based on 384.16 square inches of surface area and 5 pounds per square inch of force.

The only electric/kinetic flipper in the competition, no running out of gas here!

Re: Flipper Fest 1

Name2
Shape: Truncated Pyramid with wedge at front: See Pic
Colour: Red & Black: See Pic
Dimensions:80X70X75
Drive: 2 LEM 130s @ 36V geared at 5:1
Power: 6 NiCad 300mah batteries @ 36V
Motivation: 4 Hardox wheels with a Urethane Rubber coating (Is this allowed?)
Speed: 10 MPH Average - 15 MPH Max
Armour: 5mm Titanium
Ground Clearance: 0MM every where thanks to skirts and wedge, 6mm under skirts (too low?)
Turning Circle: 0
Weapons:
1: A large 15 KG drum sits on top of the robot, it is powered by a S28-400 Magmotor and spins at 3500 RPM and is armed with 4 2kg hardox bars that are the length of the drum
2: The wedge at the front houses a flipper similar to Warrior SKF, it takes it's power from the spinning drum and can turn over 300kg and toss 500kg
Srimech: The drum can easily self-right the robot, but the flipper can also do an equally good job.

Re: Flipper Fest 1

ooh nice, il enter orrion (my heavyweight, it's the old iron awe 4, so hp pneumatics )

Re: Flipper Fest 1

Name2

I could allow it cause technically it is not against the rules. However 300mAh is not going to get you very far. My transmitter has more powerful batteries.

Re: Flipper Fest 1

Profanity and Orrion are in, D2 is in as soon as CPA realizes he meant 3000mAh and not 300mAh.

Re: Flipper Fest 1

Sorry, Typo, It's meant to say 3000 mAh

For the others, can you please state the size of the ram and the weight and drive stats?

Problems, you say? Okay then.

Seung Mina VI

Shape: Gone back to the original III design with a few twists. She's a long, low wedge with the flipping arm in the middle, and sloped, curved sides. The rear is a very steep reversed wedge, but rounded off at the bottom where the 2WD pokes out. Like Iron Awe 5, kinda. :P

Colour: Mix of whites and greens, with some red accents thrown in.

Weight: 100kg

Drive: 2 LEM130 Lynch motors run at 49.5v, gearing is an average 6:1; no overkill, but no slouching either.

Power: 9 packs of 15 M1 A123 Lithium-Ion battery cells

Motivation: 2WD inner; 200mm CNC aluminium hubs with the usual urethane tires. The wheels are a bit wider to provide more traction while still giving more weight at the front of the robot so the flipper gets under bots easier.

Speed: 14mph

Armour: 6mm Ti/V alloy with the flipping arm made out of 8mm Ti/V. The top claws are titanium and the underbelly is 6mm polycarbonate.

Ground Clearance: 0mm at the front, rising at the sides from that to 10mm at the rear.

Dimensions in CM (LxWxH): 105 x 102 x 35

Weaponry: You know the drill for the Seung Mina series of vapourbots...what? You don't? Fine. It's a rear-hinged flipping arm, powered by 2 2.5kg CO2 tanks, a 5L buffer tank, and a 200mm stroke 150mm bore ram. This gives Mina enough power to easily clear about 1.5 tonnes, and has enough in the tank for 15 full power flips. The ram is positioned underneath the middle of the flipping arm.

Also, the spikes from the SM3 design return, only they're more pointy and curved. They're to trap wedges that try to fly over SM6.

Srimech: Flipper

Good-o?

Good-o?

Nope, sorry, not yet. FRA rules, no more than 36V nominal voltage.
