Inside Roboraptor: we dismounted it! At the time of the exit of Robosapien last year, its creator, Tilden Mark, proposed the modifiable side of its robot. Today, with the exit of the last-born child, Roboraptor, we wanted to know if it were always the case and we operated the robot with open carapace.
Large plan on the entrails of the monster. To dismount Roboraptor, you need:
some small Phillips screwdrivers
much of patience not badly of meticulousness.
There is in this robot an incredible number of screws. If you launch out in the adventure. Do not hesitate to make sketches of each element and with scotcher the screws withdrawn over the sketches. Thus you will find yourselves there easily at the time to go up. You also can scotcher the screws directly on the parts removed In order to see there more clearly, the operation starts with the disassembling of the carapace around the body and the legs. There is nothing good complicated here. It is initially necessary to remove the 5 screws on each thigh then to unscrew the 4 screws around the articulation of the leg. Attention, the back part of the carapace of the legs is held with the "hip" by a plastic nipple which should be released delicately. Once the legs postpones dismounted, it is possible to open the body. For that, there are 7 screws to remove. The 7th screw, hidden well, is located behind the front legs. For my part, I went up the legs once the removed carapaces. I also dismounted the tail by opening it then by disconnecting the connector of the sensors of tail. At this time precise, Roboraptor resembles this:
It is possible to see many details. First of all, one counts 5 motor engines on Roboraptor is: 1 for each leg 1 to make balance the head and tail 1 to make turn neck 1 to move the weight of the robot forwards or backwards
The principle is of course the same one as on Robosapien with engines D.C. current retained by springs. On the photograph, the two springs of bottom maintain the articulation of the left leg on the right that maintains the articulation of the neck and the tail. Architecture is symmetrical and the same springs find other side. Another typical characteristic of the robots of Tilden, one finds sensors of contact on each articulation. For the leg, it is the small black case located close to the 3 disc screws. The yellow wire which leaves the photograph on the right is that of the sensors of tail.
The turntable of the tail comprises 6 sensors of contact all connected in parallel.
The principal electronic chart of the robot is located on the back. In addition to the chart of the sensors of tail, one also finds a chart in the head which is only used to gather the sensors towards the two connectors with the front one.
The principal chart, the head is on the right. Circuit called IC3 seems to be a driver of engines.
It is possible to read "MD6750" on this one. One also distinguishes two potentiometers whose function is not indicated. That can be an adjustment of sensitivity for the microphones or the adjustment of the oscillator of ordering of the transmitters IR Right at side is also 4 studs to weld which act as riders of configuration. Only one is actually welded and I would be curious to know their utility.
The principal controller (IC1) of the robot is located under the chart. At side, the naked zone acts as radiator of heat for the power circuit on the top. The microcontrolor is designed especially for the robot but all its pins are identifées. To always help the handymen, each cable which leaves the chart is identified on the circuit.
Roboraptor seen top, without the chart nor the high frame By withdrawing the electronic chart and the higher part of the frame, one can a little better distinguish mechanics from the robot. The large bar which crosses right through the robot makes it possible to couple the neck with the engine of tail. Thus, when the tail goes towards the left, the head goes towards the line and conversely.
Detail of the cam of opening of mouth the end before bar is fixed on the driving block of rotation of the neck. On this one, one distinguishes a cam which comes to draw on a cable. The cable ends in the mouth of the roboraptor and this system allows in fact to make it open when the head is in bottom on the left. By withdrawing the two screws retaining the springs of tail, it is possible of oter all the system head-tail.
Front view, the head is completely removed By looking at the robot of face (even if its face to be strictly accurate were withdrawn, one clearly distinguishes the two engines from legs (in top) as well as the engine of mass transfer (in bottom). One can also distinguish on this photograph the two powerful return springs from the transfer from mass (on each side of the engine). After having given the head, the tail, the higher part of the frame and the electronic chart, we will be interested in the head of the animal like to its neck. It is by far the part most complicated to dismount and there are great risks to make a bétise with the reassembly. All starts by removing the two screws under the head of the raptor. The entr part the neck and the chin is withdrawn then as well as the two black caps which hide the microphones. After having unscrewed the white grid, one is in front of the loudspeaker of the robot.
The loudspeaker, with the site of the larynx the idea to place it here is perhaps not simplest technically but is a true success on the level of the realism of the robot. Contrary to the toys where the loudspeakers are in the chest (even in the back for Robosapien), the loudspeaker is in the throat of Roboraptor there or would be located the vocal cords and the larynx on the animal. On the photograph, one clearly distinguishes the capsule from the microphone on the pivot of the jaw. The dinosaurs did not have the reputation to be very intelligent. I do not think that it is a homage but it ya not large-thing in the head of Roboraptor.
Small platinizes electronic centralizes all the sensors. One can see the two infra-red diodes stuck in naseaux, the two microphones in the articulation of the jaw, the sensor of contact of the mouth (in the part on the left, with the top of the loudspeaker on the top of cranium, one can finally distinguish two receivers infra-red from the type operates by remote control separated by a plastic plate. By unscrewing the hoist line of mouth on the cam (see higher) and by disconnecting the cables on the turntable, it is possible to completely withdraw the head and the "vertebrae" of the neck.
The neck is coated with a "nylon sock" which turned up once leaves apparaitre the mechanism. This one is a small jewel of ingeniousness which is worth with him only the efforts of disassembling. 3 bars leave the body. The two superiors are on kneecap and follow the movement of the third which turns under the action of the engine of neck. To the base of this bar, a cam comes to actuate 4 sensors of contact successively corresponding to the 4 successive positions of the neck. Side head, the 3 bars end in a kneecap and meet on the plate which accomodates the loudspeaker. To few close with the center bars, a part comes to hold the three bars to undoubtedly prevent that those are not placed in positions which would block them. After having made the turn of Roboraptor, let us make a fast passage by the remote control.
Here, one finds oneself in a traditional configuration of a remote control with a handle of transistors, the microcontrolor and keys standards. Two points draw all the same the attention, the stud "test" in bottom on the right and the zone to weld entitled "Select (Demo) SW". We made together the turn of the characteristics of Roboraptor. Just like Robosapien, it is now with you to take the hand and to arrange it, to modify it, of the customiser, etc. Do not hesitate to announce your work to us, we will be made a pleasure of publishing them here.
