[1] Storage/Transport Case is a multi-compartment polypropylene toolbox. The box is shown in the photo above disassembled into parts 1-A, -B and -D. The tag 1-D has additional assembly notes.
[2] Manual is currently 80+ pages, with dozens of cad drawings and diagrams. View more at On-Line: The Manual.
[3] Laminated Quick Reference Card has drawings of assembled joints on one side, and script/edit/run programming details on the other.
[4] 40-Minute Video showing 11 models built with the RCS-6 in action, followed by a 30 minute step-by-step sequence showing an arm being assembled and programmed. View more at Video.
[5] Software on CD. View more at On-Line: The Software.
[6] Power Supply runs the electronics adapter and the servos.
[7] Electronics Interface connects to your computer's USB port using the supplied USB cable and runs servos under software control. The adapter also has an 8-channel 8 bit A/D, and the manual gives details of sensor construction from low-cost components, with sources and part numbers are included. View more at Electronics Adapter.
[8] USB Cable, 6' (1.8 m) with molded plugs.
[9] 6 Servomotors, currently Hitec HS422 which have dual iron-oilite output bearings. We have replaced the 1' (30 cm) standard cable with a 3' (91 cm) cable. See details at Servos as well as Hitec's own site.
[10] 6 Servo Extension Cables, 2' long, allow larger constructions and more positioning freedom.
[11] 6 Sets of Custom Servo-to-Link Mating Parts let the robot builder connect the servo output shaft to the RCS-6 links by tightening only a single screw.
[12] 11 Servo Clamps secure servos to links and to the Bread Board Base (see #18) in a variety of configurations.
[13] Cable Wraps and Pads allow easy "dressing" of servo wires along your robot's body, and Servo anti-slide pads are provided as an aid in unusual projects when servos need to be held against smooth surfaces.
[14] Links, more than 4' (1.3 m) total length if put end to end. If servos are the "muscles" of the robots, then the links are the "bones". Included are 4 each of 2-, 3- and 4-hole links, and 3 each of 5- and 6-hole links. The links are made of 6061-T6 aircraft-grade aluminum produced from our own dies to fit the servos precisely. The extrusion is then machined to form links, and hard anodized for durability and appearance. For more, see Links.
[15] Diagonal Link is a specialized extra link assembly used with the Pivot Post Base [17]. See Links.
[16] Gripper Assembly mates easily with two servos, one to open and close the fingers, and a second servo which acts as the gripper's "wrist". If, for example, your project is an arm with a wrist and gripper, you will have the remain 4 servos for the other arm motions. Remember, though, that not all arms need grippers, and not all robots are arms!
The gripper can accommodate objects up to about .9" (~23 mm). See Gripper.
[17] Pivot Post Base with pivot post and fasteners is used with the diagonal link for most arm-like constructions. This Base includes a pre-bolted steel weighting bar for stability, and remainder of this Base assembles easily with the included tools [22]. This Base, for example, is used in the Chemist, Golfer, Coffee, and Bubbler projects.
[18] Bread Board Base is used for "generic" constructions. Three clamps, ([12]), allow quick, flexible attachment of servos to this base. This base, for example, is used in the Fingers, Thrower, Dancer, and 3legs projects.
[19] Caster parts for walker projects such as 3legs. The parts are on top of the Bread Board Base in the picture for visibility.
[20] Rubber Bands for constructions such as Fingers. The bands stretch onto links to provide gripping surfaces.
[21] Toys for the robot, including a few wooden balls and plastic tees for pick-and-place demonstrations. The table tennis ball is used for throwing or hitting by models, and the spoon is used in Thrower and also just as a spoon in Coffee.
[22] Tools that are needed come with the set: A hex key and a small phillips screwdriver. Other fasteners such as plastic wing-nuts may be finger-tightened.
[23] Safety Goggles, which fit over glasses.
[24] Safety Tape, brightly colored, for marking the "do not enter" area around robot projects.
[25] Shipping Box.

Historical changes to the set include:
* The USB cable was added and the two videos combined onto one tape to make room for the cable.
* The laminated quick reference card was added. Spares of some small plastic parts were added.
* Hitec servos, made in Korea were substituted for Futaba servos (Japanese, made in Taiwan)merly. Cost on the Futaba servos became prohibitive, and Hitec has proved their product with several years of consistency and expansion of distribution into over 40 countries. The Hitec servos also have dual metal output bearings, while the Futaba units had only one.
* Most metal parts are now supplied in stainless steel (instead of zinc plated) for better appearance and weathering in all parts of the world.
* A detailed replacement parts list has been added to the manual.
