Black Widow (Crawling truck) . .
Here is my.. other title photo, I had a hard time deciding which photo to use. So I added both! There is a video at the end.
So this truck started out with my idea to make steering from linear actuators. I built the axles, and the truck body soon followed. I had 4 LA so I decided that I might as well put 4 wheel steering in it. Soon it turned into a jacked up redneck pick up. If I had a truck, it would be this one. I also consider this my first attempt at a trial truck.
Specs of the truck:
Drive: 2XL motors
Steering: 2m motors, 4 LA
Winch: 1m motor
2 sets of lights
3 IR recievers
1 rechargeable battery box
Dimensions(l X w X h) 46cm X 21cm X 21cm
Jacked up rear end. I'ma need one heckofa drop down hitch to tow that...
Suspension.. Aw yah!
It has tail lights.
Head lights too.
Steering. 4 wheel steer. This was more of a necessity because it has NO differentials, which really limit turning radius.
Also it can crab steer. The front and rear steering systems are independent, providing lots of "agility" for climbing rocks.
Tail lights again.
Head lights.. again
This has been officially named "the rats nest" Lots and lots of wires.

$ Money shot.. worth about 5 hrs of my time ;)
Suspension minus the wheel.
The base idea for the truck, this axle. I have a worm gear drive mounted in it for crawling. The gear ratio is 1:24 right now. It will go basically anywhere the driver is crazy enough to take it.
I have the axle built for modding. This means that I made it so that it can be pulled off in 2seconds. Two bushing, 2 trailing arms, and the motor wire, and it comes right off. I have another gear ratio for it 1:1.667.
Money shot with out the axles.
Steering gears, and the winch off to the right. I originally had 2 normal batter boxes mounted under here, but I found that they were too heavy for the truck to climb efficiently.
The two universals that are hanging down go to the LA on the axle for steering. The best part about having LA for steering is that they don't bog down like normal steering, and I don't have to have a clutch gear to keep my motors safe. I also didn't have to gear the motors down to make the steering work.
The winch is geared down to 1:40.008. It turns painfully slow, but It will lift the truck straight up off the ground. I also added a clutch gear to the front so it can free wheel. That was necessary also.
I am going to keep modifying this truck, and making it better. I am open to any suggestions. Thanks for looking!
