How to create a bot (Robotic car). This is what the XURAS team like most, robots. Here I'll show you how to create one:
First enter the Q menu and select a body that you want, feel free to choose any, but I have gone for the PHX Train Body.
Now we need wheels for it, select the wheel tool (doesn't have to be wire) and attach it to the body.
Now weigh the body 2 for now, when we have built it and tested it you can change it to whatever.
We need something circular, so it can look around corners and determine where it is, so select a wheel or something to put rangers on.
I'm going to use the half circle to put my rangers on.
Now select the wire ranger tool and set all the properties to:
Range: 700
Everything unticked apart from:
"Hit water", "Output distance" and "High Resolution"
Put one on the front of the car, this will allow it to see objects directly infront of it, controlling its speed.
We need some rangers on the side now, so put
four not three (If you see three, look closer, there's one on the side) rangers as shown in the image:
And on the other side
Weld the top dome to the body, and weigh the dome 2 like the body.
Now we need something to make it move, select the wire thrusters and select these settings:
Force Multiplier: 0.9 (You will see why soon)
Minimum force: Less than 1
Maximum force: Greater than 90000
Bi-Directional: Doesn't really matter either way
Make sure it works out of water, I don't mind about in, since it's not really going to go there.
Attach a thruster to the back of the car:
And one to the front two wheels (or the body):
You know those rangers we set up on an angle before? Well we need to add each side of them together. Go and select the Wire Arithmetic gate, and select the addition chip:
Place one at each side (total of two (the one that you can see that's off angle shouldn't be there)) of the car, these will be used to add up each side of rangers, to get a total distance away.
Now we wire them up, one side goes into one addition chip and the other side goes into the other chip. Simple! (Don't wire the front ranger to anything yet). Now you can see why the multiplier on the thruster has to be so low, it's because 700 X 5 on either side isn't exactly a low number. Told you there was a reason.
Until both sides are in each chip as shown:
Now for that back thruster, we wire A from that straight into the front ranger, since there's only one, we don't need an addition chip.
Now for the inside thrusters, the ones attached to the wheels (or body (or wherever)) need to go into the addition chip on that side (which is why it's good to lay it out like that).
And the other side
There we go, just about done, give it some funky colour scheme and send it off on it's journey.
If the car heads towards walls, then you've wired the thrusters to the wrong addition chip, swap them around and it will be fine.Feel free to have a mess around with it, tweak the speeds etc.
