| Armor
| 2"x4" HDPE Bar Stock 3/16" 6061 AL Plate
|}

==== Problems ====
* Low Clearance 0.5". Armor same height off ground as arena lip, got stuck on edge.
* Small Wheels (5"), Need to be large
* Difficult to service, required complete disassembly to replace belts and drum bearings.
* Weapon Pulley too large, belts vulnerable to hits. Also made of aluminum and easily damaged.
* Transmitter broke during competition. Used Hobbyking $20 Transmitter.
* 3D Printed Electronics Mount Broke
* Need Fastblow Fuse <300A
* Front Plate Fracture at screw interface with side plates, due to <0.125" material at bolt hole
* Weapon Bearings not checked after each match
** One shattered during first match, still spun but quickly seized
* Drum bolt circle was not machined properly, drums canted.
* Large flat area on rear armor, got caught on arena edge
* Underweight (113 lbs)

==== Good aspects ====
* Reliable Drum
** Spun up fast, <4 seconds
** Drum in 2 pieces, 10 0.3125" Alloy Steel dowel pins
** 4 Large Tapered Roller Bearings, 2 outside and 2 in the middle
** Wire EDM Single Tooth (Montgomery Machining Mall), easy to hold tolerance
** Hardness 53.5 HB, Heat Treated at Braddock Metallurgical Inc. for free. Did not fracture
** Drum had dowel pin circle on both sides, could be reversed when pins broke inside and were stuck
* Powerful Drivetrain: 150lb-in Gearbox Output Torque, Could push > 130lb person on tile floor.
* All wheel drive, 4 Wheels
* Stable Drive Control, robot went straight and could turn appropriately
* Good Speed: 13.6 mph, 912RPM 5" Wheel
* Zip Tied and Electrical Taped all electronic connectors
* Armor absorbed hits well
** Almost no significant damage to main frame
** Aluminum dented and sheared
** HPDE plastically deformed
** Multiple replaceable sets (2.5 Sets)
** Sheet Metal Screws, self tapping into plastic
* Tolerances
** Parts fit together well. Waterjetted jigsaw fits had 0.008" under sizing to interface smoothly
** Dial Indicated large parts on mill
** Custom Grooving Tool for pulley V-belt groove
* Used Jigs to drill holes on side plates lengthwise (Holes could not be done on mill because the part is too long)
* External chain on drive easily serviceable
* Electronics properly spec'd. Did not burn an ESC
* Tapered roller bearing worked well

==== Changes/Improvements ====
* Larger wheels for ground clearance, 6" instead of 5"
** Pockets and Slots in front plate, back plate, and side spacer to accommodate wheels
** Make hub go all the way through wheel (not 2 separate inserts)
* Properly machined drum so that dowel circles line up
* Larger Drum to utilize extra weight
* Hole instead of H slot for belt servicing so that entire bot does not need disassembly to replace belts
** Smaller weapon pulley required to accommodate hole
* Steel Pulley, not Aluminum
* No vertical holes in front plate
* Larger skids for larger wheels/drum
* Extra 2 Skids further back on side plates, redundancy in case front skids shear
* Hole in sideplate so that weapon shaft and drum can be removed without removing entire side plate
** Insert attached to side plate to hold in place
** Pocket armor to compensate for space
* Smaller Rear Armor
** Make same profile as side armor
* More Powerful Weapon Motor ([http://www.scorpionsystem.com/catalog/helicopter/motors_4/hk-45_1/HK_4530_450/ Scorpion HK 4530 450])
** More Torque, faster spinup and smaller weapon pulley needed due to less gearing
* Brighter LEDs on top plate

Csilberglied: added link to RoboGames 2017

Welcome to the '''[http://www.robojackets.org/ RoboJackets]''' BattleBots wiki! [[File:Motorama 2015.jpeg|thumb|right|400px|BattleBots team at Motorama 2015]]

== Overview ==

Everyone has seen BattleBots on T.V., fighting to the death in a gladiatorial-style arena in a shower of steel, sparks, and glory, and yet many people haven't the first clue about what it takes to build one!

RoboJackets' BattleBots team tries to solve this, by teaching members to design and build a robot 1) robust enough to take multiple beatings, but 2) strong enough to deliver its own beatings in return. A good technical challenge that takes hundreds of man-hours and buckets of love. We have built battle-ready robots in the 120 lb, 60 lb, 30 lb, 12 lb, and 3 lb weight classes, including (based on their active weapon) drum spinners, ring spinners, shell spinners, veritical and horizontal bar spinners, sumo bots, walkers, and even the occassional wedge.

We use mostly mechanical skills with some degree of electrical experience to implement our carefully CAD'ed designs, to personally manufacture the majority of our robots. Ultimately our goal is to build an awesome machine to fight one-on-one with another robot in the same weight class, all the while learning practical applications of tooling and machining, and gaining invaluable experience in the design and manufacturing process.

== The Competition ==

The competition consists of fights between robots in the same weight class. Competition rules place certain limits on weapon design and robot weight, for a fair contest and for the safety of the observers. For instance, entanglement weapons such as ropes or nets are prohibited along with invisible weapons such as electrical interference. This focuses the robot design on aggressive weapons designed to break apart or incapacitate the other robot, and the only limit on this type of weapon is that it is well engineered so as to not harm the people around it. The presence of these aggressive weapons forces the robots to be designed to withstand large shock loads, both mechanically and electrically. The challenge of the BattleBots team is unique in that a balance needs to be reached between defensive and offensive abilities, all while ensuring that the robot is very robust in all aspects. Even a single wire or bolt coming loose will cause defeat in an intense fight!  This year we plan on attending two competitions, Motorama in Harrisburg, PA and Robogames in San Manteo, CA.

== Meeting Times ==

We meet in the Student Competition Center (Building on 14th Street). Wear closed-toe shoes and a tshirt (no long sleeves) since we will be using the shop. Bring a hair tie if needed. [[BattleBots_Carpool_Info|Carpool]]

*'''BattleBots Meeting''' - Thursday 6:30 pm to 9:30 pm
