HUMANOID BUYERS GUIDE by the staff of Robot elcome to our humanoid buyers guide! If you are a newcomer to the fascinat- ing world of tabletop humanoid robots and are curious about the variety of Wproducts available in this category, we’ve got you covered. This guide is based on web research and product reviews published in Robot and is not exhaustive. However, it is a representative sampling of many of the most popular humanoids avail- able in the U.S. and Europe today. Pricing is approximate and in some cases based on vendor prices before a model went out of production. Because so many thousands of some models were produced, they are often still available as used or “mint condition used” robots, and sometimes for a song. Still floating around in the community and being actively used, they merit mention here. With the introduction of the Kondo Robot KHR-1 humanoid in the mid 2000s, the humanoid robotics market was established. Kondo was the original sponsor of Robo- One robotic humanoid martial arts competition and understood the need for more intelligent servos than those previously available for radio control hobby applications. Kondo designed new servos specifically for robots and launched the now nearly legendary Kondo KHR robot family. Humanoid robots have since proliferated and are now used for a wide variety of applications from entertainment and sport competition to educational outreach and humanoid research. While organizing this guide, we were pleasantly surprised by the large number of humanoid robots and the startling variety of choices in price, hardware and software. Whatever your preferences, you are like- ly to find the right match for your budget and interests here! We have highlighted some of the distinguishing characteristics of each robot to give you an edge in your search for that next machine destined to put a smile on the faces of those in your household (everyone loves humanoids!). Our special thanks to Lem Fugitt of www.robots-dreams.com for his guidance on humanoid bots over the years and for his contributions to this guide (ranging from photography to perspectives on particu- lar machines). We also highly recom- mend www.robotservicesgroup.com for quick, in-depth comparative data on most of the robots surveyed in this guide. lllllllllllllllllllllllllllllllllllllllllllllllll - Which of these robots will walk into your life? 32 ROBOT MAGAZINE Aldebaran www.aldebaran-robotics.com/en Futaba NAO DOF: 25 (Academics Edition); height: 23 inches.

The Robonova-1 (RN-1), now out of production but often avail- able used on eBay and elsewhere given the many thousands produced, uses an Atmel-128 based controller that can control up to 24 servos. The versatility of its controller has been highly praised by hobbyists. The approximately one foot tall RN-1 was one of the first humanoids to come with a specially designed servo, the HSR-84981HB, which features an inte- gral “idler wheel” for secure mount- ing in the brackets that comprise its skeleton. Software packaged with the RN-1 included two different pro- grams, a variant of BASIC called RoboBasic and a graphical user inter- face. The board is pre-configured to accept gyros, sonar arrays, accelerometers and other sensors, and an infrared remote is included. The stock package came with a suite of 29 pre-programmed moves enabling the RN-1 to bow, kick, do a headstand and even a cartwheel. Although sold for roughly $900 - $1,000 when it was still in production, pricing for used and mint condition RN-1s today is all over the map.

Kumotek’s KT-X comes in a few ver- sions and represents a family of humanoids. The KT-X “Superbot,” Kumotek’s flagship, has 17 servos, a 60MHz microcon- troller and a remote control (U.S. customers only). Un upgraded “Gladiator” KT-X features 19 DOF so that it can pivot (yaw) on the hip axis and has the most human-like motions. The lllllllllllllllllllllllllllllllllllllllllll “KT-X Lite” is an entry level vari- ant with 13 DOF. The Superbot comes standard with a speaker that plays .wav files and a port for a gyro/accelerometer sensor. A wireless gamepad remote control enables “real time interaction and play.” Kumotek says that the KT-S is the “first low-cost bi-pedal robot plat- form of its kind to be offered in the U.S. that (a) can be controlled using a standard wireless PS2 game con- troller…”. The controller board has 512kB ROB/64kB RAM and comes loaded with 75 preprogrammed motions. The servos on this 13.5-in. robot have embedded sensors for detecting the servo’s position in real time, and communication is RS232C (115kbps) or USB. Its “RobovieMaker” programming software runs on any standard Windows based PC. Price: $1,250 (KT-X Superbot).
