This is the official FIRST Tech Challenge Perimeter. This perimeter may be referenced as am-0481, am-0481a, or am-0481b in documentation. This is reusable from year to year and does not include soft tiles, game-specific hardware, components, or game pieces. This "b" revision is compatible with the previous "a" revision, meaning "b" version corners and panels can be used as replacement in "a" version perimeters. The perimeter is comprised of eight hinged panels and four straight panels. Once assembled, the perimeter creates an 11 feet 9 inch by 11 feet 9 inch square enclosure. The hinged corners and quick release pins make for easy assembly, requiring no tools. Side panels include a built-in wire way for easy cable management. An adjustable Perimeter Strap (am-2270a) placed under this playing surface help keep the walls square during game play.

These nylon carrying cases are for Soft Tiles foam floor mats. The bag is zippered with two large handles. Each bag is designed to hold up to 18 tiles which is half of an FIRST Tech Challenge playing field. This is the bag by itself and does not come with Soft Tiles. This bag is perfect for a team practicing at home or an event manager transporting fields to and from venues.
Soft Tiles are 2' x 2' x 5/8" thick gray floor mats that are used on the FIRST Tech Challenge (am-0481b) playing field. A full FTC field requires 36 tiles.
The interlocking edges of these tiles connect nicely for a quick setup and will stay firmly in place. The edges can be easily cut for a straight edge if desired. The tiles are double-sided with both a textured and a smooth side to suit any need. Disassembly is simple and we suggest these Soft Tile Bags for storage and transport. Each bag can carry up to 18 tiles.
These tiles are ideally suited for a variety of purposes and are perfect for exercise areas, playrooms, and workshops. The soft, durable mats would also work well anywhere that needs a bit more cushion - including camping or as an anti-fatigue standing mat.
Tiles can also be purchased in single quantities or packs of four.
This is the cable designed for the encoder that is pre-attached to the NeveRest Series of motors and gearmotors. It has a connector on the opposite end to directly interface with the REV Expansion Hub or the REV Control Hub.
2019 Update:
The 'a' version of this cable as the encoder channels swapped so that the encoder counts in the same direction as the output shaft spins. This simplifies the usage of the encoder with the various programming languages for FTC!
The NeveRest 40 is a gearmotor with an attached encoder. The output shaft geometry and the gearbox housing diameter is similar to what FTC teams are familiar with. The shaft is a 6 mm D and the gearbox housing is 37 mm diameter.
FIRST Legality:
Encoder: There is an encoder mounted to the backside of this motor. It is a 7 pulse per revolution (ppr), hall effect encoder. Since the motor's gearbox has a 40:1 reduction, then the NeverRest 40 output shaft provides 280 ppr.
Encoder Cable Options: NeveRest motors do not come with an encoder cable as we offer 3 cable options:
am-3926a allows you to connect the encoder directly to the FIRST Tech Challenge REV Controller.
am-2992 has the 4 encoder pins joined in one housing using standard 0.1" spacing.
am-2993 allows you to break out the 4 pins separately if you need them in a different order. Working with the Encoders:
Performance Specs: Force Needed to Break Gearbox: 1478 oz-in Time to Failure at Stall: 2 minutes, 54 seconds Motor Case Temperature at Failure: 190 degrees F
This conversion plate acts as a hub between larger motion components featuring a 1.875" bolt circle to components of a smaller mounting circle such as a NeveRest Gearmotor. The bore of this plate fits shafts that are familiar to FIRST Tech Challenge teams. Specifications:
These heavy blue nylon bags with wheels make it easy to transport your FTC Perimeter Field Kit (am-0481b) in two halves. Bags have 2 strong handles, one at the top for rolling and one on the side for carrying.
Each bag is designed to hold up to 1/2 of the FTC Perimeter Field Kit (am-0481b)
TWO bags are needed for an entire field.
Machine Key, steel. Used in various AndyMark gearboxes. Specifications:
The 100mm Slim Mecanum Wheel Set comes with 2 left and 2 right, and steel ball bearings. With blue steel frame and black rollers. The wheel is comprised of 12 black rollers and is able to move in any direction. Rollers are set at 45° to the axis of rotation of the wheel.
Rollers are mounted with steel ball bearings, making the roll more fluent.
Wheel Specifications:
The following hubs (purchased seperately) will work with these wheels
This is a Trilobe, thread forming, or thread rolling screw, ideal for applications where the screw is being threaded into plastic or metal. A flat washer is part of the 5/16 hex head, providing more surface area contact than a regular hex head. The increased bearing area decreases the likeliness of crushing mating surfaces. Trilobe, or Thread Rolling, screws have a blunt tapered point that requires a pre-drilled or punched hole; eliminates chips and permits replacement with standard screw. Zinc plating froms a zinc carbonate film that greatly retards the corrosion rate in a normal atmosphere, which is similar to the aluminum oxide film that forms on aluminum that accounts for its low corrosion rate.
