One of 2001’s most popular toys was Rumble Robots. While they don’t use new equipment, they mix established technologies novelly. These toys’ major draw is gaming: Players gather unique cards to trigger combat maneuvers and boost their bot’s ability. Let’s see The Operation of Rumble Robots.
The Operation of Rumble Robots
Transport To Light:
Most remote-controlled toys use radio transmitters. When you move the controls, the transmitter delivers a signal to the toy’s radio receiver at a particular frequency. A command is transmitted by a specific radio signal of electromagnetic pulses, and the toy obeys this order. For more, see The Operation of Rumble Robots.
Rumble robots work similarly by using infrared light instead of radio frequencies. An inferred remote controller is like a little Morse code lamp. They send messages by flashing a tiny LED in a unique sequence of long and brief flashes. We can’t see the LED’s infrared light, but the robot’s light-sensitive panel can. The sensor interprets the signal.

Standard TV remotes employ this technique. Inside, the Rumble Robot controller resembles a TV remote. The plastic controller housing holds:
1- Three batteries
2- A light-emitting diode
3- Two circuit boards
Most modern devices, including Rumble Robotics, use printed circuit boards. A printed circuit board is thin fiberglass with copper “wires” engraved. The cables of this intricate circuit link many electrical components. A Rumble Robot controller’s circuit boards comprise an integrated circuit (microchip), transistors, resistors, diodes, capacitors, and buttons.
When moved, plastic pads on the controller press on the circuit board buttons. Rubber buttons contain tiny conductive plates. Pressing the button presses the conductive metal component against a circuit board contact.
Contact points are usually open circuits between the battery and the integrated circuit. The fixed wires do not join, so electric current cannot reach the microchip. The conductive plate on the wires closes the circuit, and current travels from wire to wire to the microchip.
The integrated circuit determines which buttons are pushed and sends a command signal to a transistor. Transistors boost signals and ignite infrared light. Controller signals continue when buttons are pressed.
Message Acknowledged:
In the previous part, we observed that the Rumble Robot controller sends infrared instructions. Each controller has A and B settings. When you adjust settings, the microchip modifies the infrared signal flash pattern.
The robot has A and B settings. After switching from A to B, the robot will disregard A-pattern signals but record B-pattern signals. Two robots of the same model must be put on B and A. One controller would activate both others. Different models employ patterns to simplify battles.

The infrared receiver’s core is a tiny photocell that reacts to light. Photocells, which emit electrons in response to particular light frequencies, commonly use the photoelectric effect. Typical photocells have a light-sensitive semiconductor layer between two electrodes.
Whether the photocell is on or off, the battery transmits a steady current across the two electrodes. Exposing the photocell to the correct light boosts’ electron current. A flashing light will increase and reduce current in the same way. A photocell converts sunlight into electricity (see How Robots Work for more).
The Good Fight:
Like a radio-controlled automobile, a Rumble Robot features four electric-powered wheels—two drive motors spin gears to move the wheels, as seen below. The robot motors are in the bottom half. When signaled, the integrated circuit transmits an electric current to one or both motors. Depending on the current, each motor spins in two directions.
The integrated circuit may steer the robot by reversing the motor current. The robot moves ahead if both motors get a favorable current and all wheels spin similarly. When both get a negative current, the robot moves backward.
One motor receives a favorable current, and the other negative current will spin the wheels in opposing directions, turning the robot. When both motor currents are switched, the robot turns in the opposite direction. A third motor in the robot’s head operates its arms.

Furthermore, this punching mechanism has two rack-and-pinion gears. A connecting gear moves the racks as the motor spins the center gear. This design comprises two teethed parts and two smooth areas on the base of each gear. Teeth-equipped parts contact the robot’s arm-mounted racks.
When the teeth engage, the gear slides the rack and arm rearward. The rack is released when the gear turns to the smooth portion. Spring-loaded racks punch forward when released.
An Impactful Hit:
In Rumble Robot, the goal is to strike the other bots. Hits come in three ways:
• Press the terminate switch on Rumble Robots, which has a little bumper switch behind the head. The switch closes when the robot strikes the wall, or another robot hits it from behind. Once this circuit completes, the embedded controller receives a hit signal.
• Tip the robot over – Each model features an integrated gravity switch. When the robot is tilted more than 60 degrees, its pendulum gravity switch shuts an electrical connection. Switches record hits when robots knock each other over.
• A light-emitting diode (laser), similar to the controller’s laser, drains the robot’s power points. The inbuilt circuit turns on this light when you pull the firing trigger. Each robot’s base features a photocell that operates like its head.
This laser LED and photocell are adjusted to a separate frequency from the controller transmitter and receiver to avoid interference. When it detects infrared, the laser receiver notifies the integrated circuit that another robot was struck. Players need the appropriate cards to utilize the laser, punch, or boost a robot’s power.
Play Your Cards Right:
Power cards distinguish Rumble Robots from other remote-control toys. Each Rumble Robot comes with power cards, and packs include more. After sliding the correct cards through the robot’s head slot, players may activate its laser protection, punching mechanism, speed, and power points.

Each Rumble Robot includes a back-mounted card reader. The card reader functions like a grocery store barcode scanner. It has a small light and sensor adjacent to it. Each card features a unique black-and-white line design. The light travels across the line pattern when you slip the card through the slot.
