-# HBRC 2013 Challenge Robot
+# challenge-bot
-## Introduction
-
-For 2013, it is proposed that there be a "club bot".
-The goal is to learn from the 2011 "club bot" and
-improve upon it.
-
-Most introductory robots are "dead-end" robots that
-tend to strand people after they have the first
-few robot behaviors are implemented -- obstacle avoid,
-wall follow, line follow, don't fall off table, etc.
-
-One of the primary goals of the 2013 robot is to try
-to make it expandable from simple to more complex in
-reasonable incremental steps.
-
-The base is organized around 1in x 1in grid peg-board
-which is readily available from locations link Home
-Depot, Lowes, and lumber stores.
-
-There would be a variety of independent upgrades
-that could be done in whatever order the user
-feels inclined to use:

-## Rechargable Battery Upgrade
-
-This gets rid of the hassle of buying and throwing
-away AA batteries.
-
-Bill of Materials:
-
-* 2 7.2V 1300mAh LiPo Battery Packs (Trossen: BAT-7V1300M: $26/2)

-* 1 DPDT Power Switch (TBD)
-
-## Raspberry Pi Upgrade
-
-The DC-DC convert is rated for 1.5A and can be
-plugged into the breadboard. The ribbon cable
-can be assembled with just a vise. The RasPi
-allows 5V to be injected over the cable. Obviously
-the RasPi allows people to start trying out ROS.
-
-Bill of Materials:
-
-* 1 Raspberry Pi Model B 512MB (Newark: $35)
-* 1 OKI-78SR-5/1.5-W36: 5V@1.5A DC/DC Switcher (Digikey: $4.30)
-* 1 2x13 Female Ribbon Cable Header
-* 1 16-conductor chunk of ribbon cable
-* 1 2x8 Female Ribbon Cable Header
-* 1 1x8 Male to Male pins header pins
-
-## Odometry Upgrade
-
-This upgrade requires some work.
-
-Bill of Materials:
-
-* 2 AS5055 ($10/2)
-* 2 AS5055 PCB's
-* 2 Appropriate magnet ($2/2)
-* 2 GM3 to magnet shaft adaptor
-
-An adaptor from the GM3 to Magnet is needed;
-this would be custom made out of some plastic.
-In addition a custom PCB is needed to hold
-the AS5055 which is a surface mount chip.
-
-## WiFi Upgrade
-
-Something like the GMYLE using the RTL8191SU should
-do the trick. With this it is possible to network
-into your robot. There it may be necessary to have
-separate power injection for the Wi-Fi.
-
-Bill of Materials:
-
-* 1 USB WiFi Dongle with decent antenna (Amazon: ~9)
-
-## Camera Upgrade
-
-This RasPi camera has not shipped yet, but it seems
-to be nearing the end of prototyping. A USB camera
-is another alternative.
-
-Bill of Materials:
-
-* 1 RasPi Camera (~$25)
-
-## Cheap Arm Upgrade
+## Introduction
-Bill of Materials:
-* 4 Hobby servos (base twist, shoulder, elbow, gripper)
-* 1 Gripper (Jameco 358811: $20)
-* Appropriate struts
+Most introductory robots are "dead-end" robots that
+tend to strand people after they have the first
+few robot behaviors implemented -- obstacle avoid,
+wall follow, stay on table, etc.
-This is a low payload arm that can lift 10-20 oz max.
+One of the primary goals of the challenge-bot is to try
+to make it expandable from simple to more complex in
+reasonable incremental steps.
+The base is organized around 1-inch x 1-inch grid peg-board
+which is readily available from locations such as Home
+Depot, Lowes, and lumber stores.
