Rumble Robotswere one of the most popular toys to hit the ledge in 2001 . While there ’s no revolutionary machinery involved in their invention , they do combine several familiar engineering in an innovative agency . The independent lure of these plaything is their gambling constituent : Players amass special cards to aerate dissimilar combat movement and increase their bot ’s powerfulness tier .

In this version ofHowStuffWorks , we ’ll look at the various part that make a Rumble Robot work . As you ’ll see , the basic elements in a Rumble Robot are simply modify adaptation of common electronic devices we employ on a everyday basis .
Bring to Light
Most remote ascendence toy dog are operated by aradio sender . When you move the control condition , the sender sends a radio signal , at a particular frequency , to a radio pass receiver inside the plaything . The receiving set signal includes a distinctive circle of electromagnetic pulses , which represents a particular command . The toy recognizes this command and carry it out . ( SeeHow Radio Controlled Toys Workfor details . )
Rumble Robots manoeuvre on a similar system , but they useinfrared lightinstead of radio waves . An infrared outback control is like a miniatureMorse codification lamp . It transmit messages by flash a smalllight - pass off diode(LED ) in a distinctive pattern of long flashes and curt flashes . The infrared lighter emitted by the light-emitting diode is unseeable to our eye , but not to the robot ’s loose - sensitive jury . The sensor picks up the signal and decipher the message .
This is the same precept used in standardtelevision remote controls . In fact , the Rumble Robot controller face a lot like a TV remote on the inside . The plastic accountant trapping hold back :
Rumble Robots ( as well as most other modernistic electronics ) useprinted circuit boards . A printed circuit display board is a thin slice of fibreglass with lean atomic number 29 " wires " etch onto its airfoil . These wire connect a number of electric component part together in a complex lap .
The circuit boards in a Rumble Robot control let in :
When you move the plastic pads on the controller , they drive down on the circuit display panel ’s buttons . The button are just pieces of arctic that hold small conductive plates . Pressing the button push the conductive metal opus up against a contact point on the circuit board . ordinarily , each contact point is anopen sectionof the circuit between the barrage fire and the integrated circuit . In other word , the inscribed wires do not connect , so the electric stream can not flow to the silicon chip . press the conductive scale down on the wires closes the lap – the current menstruation across the plate from one wire to the next , and moves on to the chip .
The integrated circumference sort out which buttons are depress , generates an appropriate command signaling and passes it onto a junction transistor . The transistor amplifies the signal and trip the infrared light . The controller will keep sending the signal as long as buttons are depressed .
In the next section , we ’ll see what happens when this sign reach the robot ’s idle sensor .
Message Received
In the last section we saw that the Rumble Robot control transmits commands via infrared light . Each controller has an A setting and a bacillus mount . When you switch between the options , the microchip changes theflash patternof the infrared signal .
The robot has A and B configurations as well . When you switch the robot from A to B , it will ignore the A - pattern signals , but will register the B pattern signals . If you have two robot of the same mannikin , you have to go down one on atomic number 5 and one on A. Otherwise , one controller would spark off both of them . unlike models use dissimilar patterns , to make battling easier .
The key element of the infrared receiver is a smallphotocell , an electrical element that responds to light . Photocells are one widespread program of thephotoelectric effect , the discharge of electrons by certain material in response to certain frequencies of light .
The typical magic eye consist of a illumination - sensitivesemiconductorlayer , sandwiched between two electrodes . The electric battery send a never-ending electrical current across the two electrodes , whether the magic eye is exposed to light or not . When you expose the photocell to the correct form of twinkle , the boost in electrons amplifies the flow flowing across the electrons . If the promiscuous flashes on and off , the stream will increase and decrease in the same pattern . In this way , a photocell transform the scant sign into an electrical signal ( seeHow Solar Cells Workfor more on this appendage ) .
The electrical signaling passes on to the automaton ’s central incorporate circuit . ground on the digital pattern of this sign , the integrate circuit carries out certain action , such as moving forward , turn or give a punch . In the next section , we ’ll look at the components involved in these activity .
Fight the Good Fight
Just like a radio - controlled railroad car , a Rumble Robot has four wheel , which are power byelectric motor . As you’re able to see in the picture below , the Rumble Robot has two drive motors , which spin a series ofgearsto move the automaton ’s wheels . These motor are put up in the bottom one-half of the automaton .
When the integrated circuit receives the appropriate signal , it sends an electric current to one or both of the motors . Each motor can spin in two guidance , bet on the way of the stream . ( SeeHow Electric Motors Workfor point . )
By reversing the flow flowing to either motor , the integrated circle can change the robot ’s direction . If both motors receive positive stream , all wheels will whirl the same way and the robot will move fore . If both receive negative electric current , the robot will move backward . If one motor receives positive stream and the other receives damaging current , the bicycle on each side will spin in diametrical directions , and the automaton will turn . If the currents are then switch for both motors , the golem will become in the diametric counseling .
The robot has a third motor in its head that moves the arms back and forth . As you could see in the picture below , this punching mechanism consists of tworack - and - quill gear wheel . The motor turns the key gear , which turns a attached paraphernalia that moves the racks .
In this design , the base of each gear mechanism is notch on two side ; that is , it has two sections with tooth separate by two smooth sections . The sections with teeth engage the tooth of the racks , which are attached to the robot ’s arms . When the tooth are engaged , the gear will slither the wheel ( and the arm ) rearwards . When the gear rotate around to the smooth plane section , it releases the rack . The racks are give - load , so they punch forward on sack .
This is the particular mechanism at work in " Lug Nut . " Other Rumble Robots have dissimilar punching mode , with dissimilar gear arrangements , but the basic elements are fairly like .
The object of a Rumble Robot biz is to get your automaton to shoot down effective blows against your opponent ’s golem . In the next incision , we ’ll see how Rumble Robots register these hits .
A Very Palpable Hit
In a Rumble Robot match , the object is to score hits on the contradict bots . There are three ways to score hit :
To use the laser , start the punching mechanism or increase a robot ’s power , player have to collect the right cards . In the next section , we ’ll see how Rumble Robots read these cards .
Play Your Cards Right
The main thing that sets Rumble Robots apart from other remote mastery toys are thepower cards . Each Rumble Robot comes with a set of power cards , and additional cards are useable in separate packs .
By skid the proper sequence of cards through a slot in the robot ’s head , players can actuate the robot ’s laser defense lawyers , punching mechanism , speed and ability points .
Each Rumble Robot has a circuit board scanner one-armed bandit on the back of its head .
The card reader works just like abarcodescanner at a grocery store . It has a bantam light pose right next to a tiny light sensor . Each card has a classifiable pattern of black and white lines . When you slide the card through the slot , the beam of Christ Within pass over the billet radiation diagram . The clean lines reflect a lot of light back to the sensor , but the smutty transmission line absorb most of the Inner Light ( seeHow Light Worksto incur out why this happens ) .
Just like the infrared detector photocell , the scanner sensor translates the light radiation pattern into an electrical sign . The robot ’s integrated circuit read this signal and turn on the Modern move or boosts the golem ’s tycoon level . When the robot is defeated , or the power cuts off , the integrate lap is reset . It has to " learn " the movement all over again .
With the popularity of Rumble Robots , we ’re certain to see many standardised fighting toys in the future . Like Rumble Robots , these miniature will combine a stock remote dominance system with a master of ceremonies of interactive features .
