A device for registering a bone for a robotic shoulder arthroplasty with

• a surgical robot, the device comprising:
• a first portion engageable with a first portion of a bone, the first portion including:
• a stopper connected to an internal portion of the first portion and extending therefrom;
• and
• a bone spike extending from the stopper, the bone spike engageable with the bone, the stopper engageable with the bone to limit penetration of the bone spike into the bone;
• a second portion engageable with a second portion of the bone, the second portion connected to the first portion and rotatable with respect to the first portion;
• a registration device connectable to the first portion and configured to interface with the surgical robot for registration of the device and the bone;
• an actuator engageable with the first portion and the second portion to move the second portion toward a closed position away from an open position;
• an insert connected to one or more of the first portion and the second portion;
• and
• a second bone spike connected to the insert and engageable with the bone, the insert operable to move the bone spike with respect to the first portion and the second portion when the bone spike is engaged with the bone to adjust a force applied to the bone by the bone spike.
