Claim 0:
1. A pipe repair apparatus for repairing partially collapsed pipes, the pipe repair apparatus comprising:
an actuation assembly comprising:
a plurality of actuation arms;
a plurality of hydraulic cylinders; and
a plurality of hydraulic lines, wherein each hydraulic line in the plurality of hydraulic lines supplies hydraulic fluid to a respective hydraulic cylinder in the plurality of hydraulic cylinders, wherein each hydraulic cylinder in the plurality of hydraulic cylinders is configured to move a respective actuation arm in the plurality of actuation arms between a retracted configuration and an extended configuration to move a partially collapsed part of a partially collapsed pipe from a partially collapsed form to a non-collapsed form; and

a control module configured to control each individual hydraulic line in the plurality of hydraulic lines such that each actuation arm in the plurality of actuation arms is actuated independently, wherein the control module is configured to control at least two of the hydraulic lines in the plurality of hydraulic lines such that at least one of the actuation arms in the plurality of actuation arms applies a different force to the partially collapsed pipe compared to at least one other actuation arm in the plurality of actuation arms.
