Robot arm, having: a plurality of members and a plurality of joints, which connect the members to one another in an articulated manner, wherein the members, in interaction with the joints, are designed to carry a load and to move said load in space, and the joints can be automatically adjusted by means of motors in the robot arm in order to move the members, wherein, of the members, at least a first member (12.1) has a first housing (14.1) and a respectively adjacent second member (12.2) has a second housing (14.2), and the housings (14.1, 14.2) are designed to transmit forces and moments, which occur on account of the dead weight of the robot arm and/or of the load, in each case to the adjacent member (12.1, 12.2), and wherein the first housing (14.1) of the at least one first member (12.1) and/or the second housing (14.2) of the second member (12.2) have/has a deformation element, wherein the deformation element is designed to form a buffer body in a joint gap, which can be varied on account of the associated joint being adjusted, between the first housing (14.1) and the second housing (14.2), said buffer body at least substantially or completely filling the variable joint gap, characterized in that the buffer body is attached to the at least one first member (12.1) and, in the non-deformed basic shape thereof, is designed to maintain a minimum distance of 1 to 5 millimetres from the second member (12.2), or characterized in that the buffer body is attached to the second member (12.2) and, in the non-deformed basic shape thereof, is designed to maintain a minimum distance of 1 to 5 millimetres from the at least one first member (12.1). a plurality of members and a plurality of joints, which connect the members to one another in an articulated manner, wherein the members, in interaction with the joints, are designed to carry a load and to move said load in space, and the joints can be automatically adjusted by means of motors in the robot arm in order to move the members, wherein, of the members, at least a first member (12.1) has a first housing (14.1) and a respectively adjacent second member (12.2) has a second housing (14.2), and the housings (14.1, 14.2) are designed to transmit forces and moments, which occur on account of the dead weight of the robot arm and/or of the load, in each case to the adjacent member (12.1, 12.2), and wherein the first housing (14.1) of the at least one first member (12.1) and/or the second housing (14.2) of the second member (12.2) have/has a deformation element, wherein the deformation element is designed to form a buffer body in a joint gap, which can be varied on account of the associated joint being adjusted, between the first housing (14.1) and the second housing (14.2), said buffer body at least substantially or completely filling the variable joint gap, characterized in that the buffer body is attached to the at least one first member (12.1) and, in the non-deformed basic shape thereof, is designed to maintain a minimum distance of 1 to 5 millimetres from the second member (12.2), or characterized in that the buffer body is attached to the second member (12.2) and, in the non-deformed basic shape thereof, is designed to maintain a minimum distance of 1 to 5 millimetres from the at least one first member (12.1).
