Patent attributes
An example robotic gripping apparatus includes a robotic wrist and a motor contained within the robotic wrist. The motor includes a drive shaft that rotates about a primary axis during motor operation. The robotic gripping apparatus also includes a cylindrical worm gear, connected to the drive shaft, that encircles the motor and rotates about the primary axis during motor operation. Additionally, the robotic gripping apparatus includes two or more robotic fingers, each having a proximal end and a distal end. The robotic gripping apparatus further includes two or more spur gears corresponding to the two or more robotic fingers. Each spur gear is attached to the proximal end of the corresponding robotic finger. Each spur gear engages the cylindrical worm gear and rotates the corresponding robotic finger when the cylindrical worm gear rotates about the primary axis.
