## Abstract

An apparatus is for collecting and transporting bales. The apparatus includes a transport assembly and a grasping assembly operatively connected thereto. The transport assembly includes a bale loading platform extending above and mounted to a chassis. The bale loading platform comprises at least one bale conveying section in including a bale conveying mechanism. The grasping assembly includes a mechanical arm having a prehension end effector engageable with the bales. The grasping assembly is configurable between a bale engagement configuration for engaging a corresponding one of the bales laying on the ground, a bale capture configuration for capturing and lifting the corresponding one of the bales off the ground and a bale release configuration for releasing the corresponding one of the bales onto the bale loading platform and comprises a movement absorption mechanism operative to substantially cancel the forward displacement of the apparatus during the capture of the bales.
