A clamping apparatus includes a clamping frame, a first guide, a clamp, a linear driver, and a pressure sensor. The first guide is disposed on the clamping frame. The clamp is slideably engaged with the first guide, the clamp being configured to linearly move along the first guide to adjust a distance between the clamp and the clamping frame. The linear driver is connected to the clamp, the linear driver being configured to cause, at least in part, linear motion of the clamp. The pressure sensor is configured to sense pressure applied to an object clamped between the clamp and the clamping frame.
