![]() The logic gates are used to differentiate between various power signals. What is Digital Circuit?Ī digital circuit is a type of circuit that operates on different logic gates. Some of the important components of a digital circuit include registers, transistors, battery and many more. These circuits consume relatively less power as compared to analog circuits. We use this kind of circuit to make logic gates and transistors. The Digital circuit is one such circuit where the signal exists in one of the two states which are 0 and 1. It can perform different types of Boolean operations. The main purpose of this circuit is the transmission of power to the different components of the circuit. It is used in various electronic devices for different purposes. However another source for this number has not been identified.Digital electronics operate on digital signals and a digital circuit is an integral component of digital electronics. Additionally according to "Techno Fantasies Toy Robots From Japan" by Alan Bunkum, only approximately 10,000 units were produced and mostly sold in the North American market. The high price and low availability is mostly due to most people not being able to afford or justify the steep $600 price tag in the 80s. "Brand new" ones go for $800+ almost always. Ones in good (working) condition commonly go for $600 to $1000. Today, the 2000 remains to be one of the most difficult to find and acquire robot in the Omnibot line, with "as is" bots going for anywhere from $180 to $500+ USD. Sylvie's Omnibot 2000 next to a Corsair 400C The method it used to reset itself was entirely mechanical, relying on microswitches to be pressed down by the parts themselves once they were in the correct positions. Upon powering the robot, it would also perform a "self-check" sequence, in which it reset all motorized parts and played the "Omnibot Sound". Pressing the "Gear Change" button would switch the gear to low gear, which was much slower than high gear and allowed for extremely precise adjustment. Omnibot 2000 also had two gears, which could be changed by the user. Instead of a joystick, the Omnibot 2000 used two flat directional pads for both its own movement and the motorized arm. The remote was also completely redesigned. The robot could also handle multiple functions at once, allowing smooth turns and more fluid manipulation of the motorized arm. Instead of having a clearly audible tone for each function, the Omnibot 2000's remote broadcast a single high-pitched tone at all times and overlayed the "function" tones at a much lower pitch. The remote control system was also completely overhauled, compared to the Omnibot 5402. As with the original Omnibot, the computer unit was also electronically seperate from the robot. The remote also took four AA batteries like the Omnibot 5402's. Omnibot 2000 required the same configuration of batteries as the original, being an included rechargeable battery that powers the main components, and two AA batteries for the built in computer. This robot was likely inspiration for Short Circuit's "Johnny Five" robot. ![]() It also had an altered design with a "neck" and "head" raised from the body. This model also had a motorized tray and a motorized arm controlled by the remote. It had all the features of the Omnibot including the built in computer, cassette tape, wheels for moving, microphone, and speakers. This was the highest end robot in the Omnibot line at the time. It's launch price was approximately $600 USD, which is worth over $1000 USD today. Omnibot 2000 (model 5405) was an upgraded version of Omnibot 5402 introduced by TOMY in 1984. ![]()
