How to regulate amprage for a combat robot Answered

Hi everyone I am currently in the process of designing a combat robot with a max weight limit of 250lbs. the current drivetrain motors that I am using need 200 amps minimum to move the robot if fully loaded to 250lbs. The max stall amperage the motor will draw (when the stall torque is reached) is 856 amps I can not currently find an electronic speed controller that can safely handle that many amps or is in my price range. So my thought was to buy a 300-400 amp ESC and then set up an amperage regulator so that if the motor stalls and asks the ESC for more then 300-400 amps (whichever I decide to buy) when it asks the battery for that many amps the regulator will either block the current or only allow a safe amount of amps to the speed controller. I'm very new to detailed electrical side of this stuff so I don't know what exactly I'm looking for or where to find it. I would use a fuse but if the fuse blows in the middle of a match then I cant move which will cause me to lose by KO so what ever I do it must limit how many amps the speed controller can draw from the battery and then after it no longer asks for that many amps it allows it to function as normal. Thanks Guys!!

If you have a big motor that requires massive amounts of current to run properly than you also need a suitable power supply - period.

Ya I understand that that's not my issue I need something to keep the battery from send more amps then what my ESC can handle even if it asks for more.

Well, you do not understand.
The ESC drives the motor, if it takes more than what it can handle it means your system has massive design flaws.

You an get motor controllers with current limiting abilities but again, if the motor needs more for the task it will just stall.
For every action there is an equal and opposite reaction ;)
