You should look for a stronger way to beef up that frame; especially running along the length of the robot. I would suggest making the ribs along the corners of the box extrusion have at least a .625 or .75 lip.

Also, what kind of CNC machine would this be produced on? If it's just a regular milling machine, you'd honestly be staring at the machine for days to machine those side rails. I've seen even simple triangulation patterns take an hour.

A much better solution would be to reduce the number of pockets in half by using larger, triangular-shaped pockets. This would be harder, better, faster, stronger, and a lot easier to machine. (Time is money during the build season).

(Remember, a 150 pound force on a robot frame would be the equivalent of static loading if the robot were to push against a wall. During impacts, the force skyrockets in short bursts, which could easily exceed the 150 or 300 pound load test and bend your frame.)
