Sliding Elevator Bearing Block Kit

Coral (also known as Game Piece 1) is a 11 ⅞ in. long (~30 cm) piece of 4 in. diameter Schedule 40 Cellular (Foam) Core PVC pipe. Coral has a 4-in. (~102 mm) inside diameter and a 4½-in. (~11 cm) outside diameter. The Coral sold here is from the same batch and manufacturer used on official fields. 

REEFSCAPE℠ game piece pre-orders are not eligible for a return, nor can the order be combined to ship with other  products or orders. Payment methods for the pre-orders cannot be changed after payment has been received. If a pre-order is canceled prior to shipping, store credit is the only refund option available.

The Grasshopper nut, produced with the help of James Cole-Henry from FRC team 95, The Grasshoppers, is an innovative battery solution to increase the reliability of battery terminal connections.

Compliant Stars are the perfect thing for intake mechanisms. The soft material gives way to allow rigid objects to be manipulated easily. A line of multiple stars on a driven hex shaft creates a very effective roller that ignores variations in the objects being driven. The multiple-spoke design allows the star to act as a brush, creating more surface area to interact with and grab objects. This makes for high-performance intakes and internal conveyors. A shaft collar may be used to make absolutely sure the wheels stay clear of other mechanisms or maintain consistent spacing. Molded into the star are several guidelines. Cut the star at the lines (or elsewhere) to create more compact mechanisms. 

Different durometer ratings give each Compliant Star unique characteristics. Green stars (35A durometer) are the softest and most compliant around objects, while orange (40A), maroon (45A), and blue (50A) wheels are increasingly firm. Black (60A) is quite firm, while the Gray (80A) is nearly rigid. The increased firmness also allows the latter wheels to carry a higher RPM rating

Looking to expand your robot battery cables? Well 4 AWG just may be the answer for you. The larger wire gauge provides less resistance and therefore can prolong your battery life. Just hooking up cable straight to a battery is not recommended, which is where this connector kit comes in. This SB120 Connector handles 48V and provides a quick connect and disconnect from battery to robot.

Specifications

• Gauge: 4 AWG
• Material: Red Plastic, Copper
• Weight: 0.2 lbs

This is the same pulley used on the Thrifty Elevator Dyneema Pulley Kit. Works great with 1/8" dyneema rope and has a 1/4" ID bearing in the center allowing teams to use a bolt to easily mount it and have it spin freely.

1.15" OD with a .365" groove will let this pulley work with other rope options as well.

Note: Molded plastic cases have begun shipping with all encoder orders!

The Thrifty Absolute Magnetic Encoder was designed to provide teams a lower cost option for absolute position sensing. Simply plug the included 3-wire PWM style cable into your controller of choice and read the included magnet's absolute position. This device can connect directly to the RoboRIO as well as the REV Spark Max or CTRE Talon SRX.

Encoder Revision Updates Include -

• Switched to through hole connector to improve strength and assembly
• Cases are produced in ESD safe materials
• A J2 jumper spot has been added. Simply solder the jumper spot and the encoder will run in 3.3v mode. See the user guide for more details.

There are 60 RGB LEDs per meter, and you can control each LED individually! You can set the color of each LED's red, green and blue component with 8-bit PWM precision (24-bit color per pixel). 

The LEDs are controlled by shift-registers that are chained up down the strip so you can shorten or lengthen the strip. Only 1 digital output pin are required to send data down. The PWM is built into each LED-chip so once you set the color you can stop talking to the strip and it will continue to PWM all the LEDs for you

It comes as a full 8.2ft (2.5m) strip and can be separated at each junction between LEDs for customization. Add in a couple connectors and you can separate sections and still control them all together.

Specifications:

• WS2812b chip (WS2811 IC built in SMD5050)
• 60 LEDs per Meter (150 Individually addressable RGB LEDs on the 8.2 ft section)
• Maximum 5V @ 60mA draw per 1.3" strip segment which has 2 LEDs on it (both LEDs on full brightness)
• Maximum 5V @ 4.5A draw for entire strip (Entire strip on full brightness)
• Power: 15 Watts
• Rated Life: 50000 Hours
• 5VDC power requirement (do not exceed 6VDC) - no polarity protection
• 1 integrated RGB LEDs per segment, individually controllable
• LED wavelengths: 630nm/530nm/475nm

The MK ES17-12, 12 Volt, 18 amp-hour sealed lead acid battery with nut and bolt connector has proven to be a trustworthy power source for many FIRST Robotics Competition robots. 

The batteries will be packed within a 7"x7"x7" box (aka: interior box). A 3/4" layer of closed-cell foam will be packed around the interior box, within a 9"x9"x9" box. The entire weight of this double box packing assembly will be approximately 29 pounds.

Two (2) batteries are shipped within one box for this price.
