In terms of being able to handle the load though, would 775 pros motor and gearbox and SPARK motor controller theoretically work?

thanks again guys

Strictly speaking, any motor can move any load. It's just a quesiton of how fast.

In terms of "handling the load", these are the factors you'll need to identify:

• How fast does the robot need to move?
• How much weight is it carrying (you already answered this)?
• A bit more about the geometry of the drivetrain (to estimate how much it's going to scrub/fight itself when it tries to turn)
• The material of the tread surface
• The surface it's driving on

The first question will identify the speed of your drivetrain, and the others help answer the question of how much torque you'll need the drivetrain to output. Multiply these together, and you get how much power you'll need in your drive; that'll allow you to pick an appropriate motor and gearbox for the drive.
