Make sure your material is all good and the supports will hold it and you should be set.
400ft lbs?
For totes cantalievered like 14" out from the front of the robot, I only get arounf 70ft-lbs for a 60lb load. I though you were only supposed to consider the X-distance, not the Y height for torque caused by gravity.
Could you please share your calculations?
