Difficulty: Kit requires screwing wheels and lid in place (hex keys included). Additional circuitry can be as complex as you make it. Recommended for ages 12+ (10+ with a parent) if using a microcontroller for programming.


The Viper basic platform kit is a perfect base to add your own circuitry for sumo robots, line followers, maze solvers, or any of your own ideas!

The custom-formed aluminum chassis has plenty of strength and space for additional components and upgrades. 50:1 ratio Spark gearmotors with 2" Lite Flite wheels provide both speed and pushing power, and a sporty vacuum-formed lid keeps all the guts inside during a match.

The Viper kit is fully intended to be sawed, drilled, modified, and upgraded. Its base weight is only 333grams (11.75oz) leaving 121grams (4.25oz) for additional parts if entering the Antweight (1lb) weight class, or 546g free if entering the Kilobot (1kg) weight class. (Weighed with 2x 9V batteries.)



Dimensions:
Width: 17.1cm (6.75")
Length: 13.7cm (5.375")
Height (measured at rear when on wheels): 5.7cm (2.25")
Weight: 305grams (10.75oz) (weight is with 2x 9V batteries)
Large area of 16.8x6.0cm (6.625x2.375") to mount extra components, with a 3.2cm (1.25") tall block in the center to fit circuitry or servos.

Kit Includes:

Chassis: (purchase)	17gauge (0.043") thick, 5052 alloy Aluminum punched and formed baseplate (pic). Has mounting holes for motors and lid.
Motors:	2x 50:1 Spark Gearmotors
Wheels:	2x 2" Lite Flites are soft and grippy.
Hubs:	2x Lite Hubs are the lightest way to attach your wheels to your motors.
Power Switch:	A clever switch (pic) that you unplug to power on, using a 3.5mm mono headphone jack. Plug can be used for charging rechargeable batteries if you plan to upgrade.
Lid: (purchase)	Custom 0.040" thick vacuum-formed polycarbonate lid (pic) keeps all the wires and components inside the robot. (Not recommended to be the only armor against weaponed opponents.)
Screws:	Four 2-56x0.1875" screws for mounting the motors. Eight 4-40x0.25" screws for fastening lid. Four 4-40 setscrews for Lite Hubs. Two hex wrenches included for screws and setscrews.
Instructions:	Detailed instructions with many pictures and tips for getting more from your robot. (Download here)

New!  The Robotics User Group has completed a review and has given the Viper R/C Robot Kit the higest rating possible!  Follow along as they assemble the kit and give helpful hints and ideas for future upgrades in over 30 minutes of video.




Requires:
One or two 9V batteries (two doubles run-time). We recommend Duracell Procell (PC1604) for over two hours of run time and bursts of 12A (using 2 batteries). Procell's also tested well running a HXT 12kg-cm servo at 1.5A continuous (while driving) for well over 15 minutes.

Ships within 2-3 days.

• Available unassembled only. Everything is drilled and tapped for screws but needs to be screwed together (includes instructions).
