Ok We'r back.

The stalker robot is returning.
For those of you who need the intro to this project may i introduce the 1st and 2nd Gen design from 2009:
1st gen

2nd gen


The idea behind this project is to fabricate a fictional robot into a working physical scale model.
The inspiration comes from a mechanical vehicle from a computer game designed by Insomniac Games, called "Resistance Fall of man"


Unfortunately the robot never received its body armour, nor did it walk due to mechanical design floors and technical ability.

We hope this will not be a problem this time.
i call on the Programmers here for your supreme
guidance and ability to indulge us with your
superior knowledge of the programming world.

Lets get to it....

Using the Newly designed chassis, thanks for Eric (DialFonZo) i am able to start constructing the 3rd Gen design.
Here is the Chassis that arrived this week.



The SSC-32 will be replaced with the ARC-32 later this month.

Welcome back!

Pretty colors!

You writing add-copy now?

Very cool! And good on Eric for the frame. Have you figured the IK yet? I havent worked it out but I've been thinking that you could figure the coxa angle with a vector projection onto a plane. Orient a reference plane normal to the rotation axis of the coxa. Make a vector from the origin to the point representing the end of the foot. Project that vector onto the plane you made. Then use the components of the resulting 2d vector to calculate the angle.

Just a thought. I'll try to work out the math this weekend.

NICE...!

It's cool with the LED chaser under the controller... nice to see that it fit..

Innerbreed:
Do you want the chasis to be open source ?

Looking forward. If only i could help with the programming ...

Always liked Robot... Now i am learning to make some...! Wonderfull...

thanks guys,

once i start building this up we will get a better look at how things will work. Open source code will make the project far more interesting and as i have little knowledge on how to start working out the math, it would help immensely.

@Eric, yes the board fits very well and looks great when its powered up.

Some images i took last night of the COXA and FEMUR parts. simple workings.

I just recently bought and finished Resistance: Fall of Man - I fully support this project! Unfortunately I cant help with any code or building advice (having only just managed to make my own hexapod work) but I will supply enthusiasm!!

thanks for the support. on a side note.... awesome game.

I will post DXF files tomorrow (on another pc.. )
And it look awesome with electronics on it..

iv been looking at the scale of the build and iv worked out from an image i have of one of the legs that id need to build this thing massive.

image leg dimensions:
Coxa =45mm
Femur =90mm
Tibia =150

so from using the dimensions i already have from the coxa (70MM)this is how the leg scales up!

Coxa =70MM
Femur =145MM
Tibia =225MM
!!!!
HUGE!

What is the best way to calculate torque required?
