摘要： A drive system includes a linear actuator with a drive shaft and having an actuation axis extending along a length of the linear actuator. A motor assembly of the drive system couples to drive shaft and is configured to rotate the drive shaft about the actuation axis of the linear actuator. The drive system further includes a nut attached to the drive shaft and a carrier housing the nut. A linkage system of the drive system extends from a proximal end away from the motor assembly to a distal end. The proximal end of the linkage system rotatably attaches to the carrier at a first proximal attachment location where the first proximal attachment location offset is from the actuation axis. The drive system also includes an output link rotatably coupled to the distal end of the linkage system where the output link is offset from the actuation axis.
