Omnibot

The Omnibot OOM (later released in North America as the "Hearoid") was closely based on the standard Omnibot. Changes included a more anthropomorphic head design, remotely controlled light-up eyes that acted rather like headlights, and a more sophisticated remote controller that included primitive voice control.

Radio Shack retailed a version of the Omnibot named the Robie Sr.. Made by Tomy in Japan, these were essentially a standard Omnibot, but with the dome-shaped head replaced by the more anthropomorphic head of the Omnibot OOM / Hearoid, and the sound is different (Robie Sr. robot sound) compared to the original Omnibot.

The Omnibot Jr., also known as the "Charmmy", was a 10.5 inches tall remote controlled robot with an attachable tray, featuring styling reminiscent of the original Omnibot. Simultaneously released by Radio Shack as the Robie Jr., Omnibot Jr. included a microphone on either side of the robot's head that allowed it to hear an ultrasonic sound emitted by the remote controller. The dual microphones allowed Charmmy to determine the rough direction of the controller, and navigate to its location - sometimes even around corners. The Omnibot Jr. was also equipped with a bump sensor that allowed it to navigate around objects, and this sensor was also used along with sensors in the arms to trigger several recorded announcements should the robot bump into an object or an item be placed on the tray.

The classic Omnibot had a cheaper, smaller cousin known as the Verbot, known in its native Japan as the KI*KU*ZO. At nine inches tall, the Verbot was the mid-sized option compared to the smaller Dingbot and the larger Omnibot. It was somewhat similar to the Omnibot in appearance but was much more limited in features. The Verbot also came with a wireless remote control that could operate the robot through voice commands. Up to eight commands could be programmed. The Verbot could move forward and backward, left and right, on command. The Verbot was also able to pick up small objects, a feature many toy robots of the era lacked. The robot expressed some personality by blinking and smiling. Disadvantages common to the Verbot were that it was quite noisy, reprogramming was necessary every time the robot was powered up again, and as with all of the Omnibot series its white plastic body would turn yellow if left in the sun. The Verbot was actually quite complex, utilizing a single motor for all its movements and an intricate set of gears for picking up objects. Programming Verbot was accomplished by pushing one of the buttons on its front panel and holding it down while the corresponding action was spoken into the remote control's microphone and then releasing the button. As with most Omnibots, losing the remote meant the robot could not be used to full capacity, but some hobbyists have modified cheap 1980s walkie-talkies for inputting voice commands.

In 2006, shortly after the merger of Tomy and Takara, the company first unveiled a prototype for a new Omnibot, initially called "Omnibot 2007: i-SOBOT" but which has since been officially named, "Omnibot 17μ: i-SOBOT." ("μ" is the Greek letter "mu" symbolizing micron, referring to the specs of the servo motors) in Japan and simply "i-SOBOT" in the U.S. market. i-SOBOT was scheduled to go on sale in Japan in October 2007 (Japanese language with blue and white color), but an English language, black and grey version went on sale first in the U.S., in September, 2007.

i-SOBOT, which has been certified by Guinness World Records as "the world's smallest humanoid robot in production" is equipped with 17 proprietary servo-motors and can be controlled by an IR remote controller and also via voice commands. It is capable of speaking hundreds of words and phrases and has nearly 200 pre-programmed actions, plus allows additional programming by the user via the remote control. The retail price is approximately ¥30,000 in Japan and $350 in the U.S. i-SOBOT is fully bi-pedal. In 2013 the new robot i-SODOG will come out from Tomy.
