Help with sizing robot anchors

The robot weight is 1380kg
I have a robot with max reach swinging around with a weight of 110kg at the end at 125 degree/s
I am not sure if the anchors I use are strong enough to hold it down assuming i mount the robot at the centre of the mounting plate
Any advice with doing calculations to do a sanity check?
I am also using M20 bolts to mount the robot to the base with 24mm thread engagement Class 12.9 bolts x 8 around the diameter Space around roughly at L1=300mm

Thanks

Robot manufacturers provide those load/moment figures for mounting the arm. This covers max spec speed & max spec payload at all configurations.
You must design a mounting situation to meet those applied force and moment loads. Pretty much a simple statics analysis with a safety factor will cover it.

The anchor manufacturer provides tensile, shear load, and pull-out force data for their anchors.
