Patent Number: 
Section: claims

1. An apparatus for positioning articles at desired positions in a nuclear reactor, the apparatus comprising:a shoulder having a rotatable mount configured to mount at an edge of the reactor;a back arm extending from the shoulder; anda front arm rotatably connected to the back arm, wherein the front arm is shaped to hold an inspection apparatus at an end of the front arm farthest from the back arm, wherein the shoulder includes a motor and a manual drive both configured to rotate the front arm with respect to the back arm. 2. The apparatus of claim 1, further comprising:an installation blade extending vertically upward from the shoulder, wherein the installation blade is shaped to selectively engage with a manual handling pole and move the entire apparatus. 3. The apparatus of claim 1, wherein the back arm connects to the front arm at an elbow permitting rotation of the front arm through a vertical axis with respect to the back arm. 4. The apparatus of claim 3, wherein the back arm and the front arm are at different vertical heights so that the front arm can be rotated at the elbow to fully overlap with the back arm vertically. 5. The apparatus of claim 1, wherein the rotatable mount is a mast extending vertically downward from the shoulder and rotatable on a vertical axis with respect to the shoulder, and wherein the shoulder includes a motor configured to rotate the shoulder with respect to the mast on the vertical axis. 6. The apparatus of claim 5, wherein the shoulder further includes a manual drive configured to rotate the shoulder with respect to the mast on the vertical axis. 7. The apparatus of claim 1, wherein the front arm includes a moveable clamp at the end of the front arm. 8. The apparatus of claim 1, further comprising:a connection providing power and data to the shoulder when submerged in a fluid from operators outside the fluid. 9. An apparatus for positioning articles at desired positions in a nuclear reactor, the apparatus comprising:a shoulder having a rotatable mount configured to mount at an edge of the reactor;a back arm extending from the shoulder; anda front arm rotatably connected to the back arm, wherein,the front arm is shaped to hold an inspection apparatus at an end of the front arm farthest from the back arm,the back arm connects to the front arm at an elbow permitting rotation of the front arm through a vertical axis with respect to the back arm, andthe back arm and the front arm are at different vertical heights so that the front arm can be rotated at the elbow to fully overlap with the back arm vertically. 10. The apparatus of claim 9, further comprising:an installation blade extending vertically upward from the shoulder, wherein the installation blade is shaped to selectively engage with a manual handling pole and move the entire apparatus. 11. The apparatus of claim 9, wherein the front arm includes a moveable clamp at the end of the front arm. 12. The apparatus of claim 9, further comprising:a connection providing power and data to the shoulder when submerged in a fluid from operators outside the fluid. 13. The apparatus of claim 9, further comprising:a float positioned on the back arm away from the shoulder so as to counter torque on the shoulder from the back arm and the front arm when immersed in water. 14. An apparatus for positioning articles at desired positions in a nuclear reactor, the apparatus comprising:a shoulder having a rotatable mount configured to mount at an edge of the reactor, wherein the rotatable mount is a mast extending vertically downward from the shoulder and rotatable on a vertical axis with respect to the shoulder, and wherein the shoulder includes a motor configured to rotate the shoulder with respect to the mast on the vertical axis;a back arm extending from the shoulder; anda front arm rotatably connected to the back arm, wherein the front arm is shaped to hold an inspection apparatus at an end of the front arm farthest from the back arm. 15. The apparatus of claim 14, further comprising:an installation blade extending vertically upward from the shoulder, wherein the installation blade is shaped to selectively engage with a manual handling pole and move the entire apparatus. 16. The apparatus of claim 14, wherein the front arm includes a moveable clamp at the end of the front arm. 17. The apparatus of claim 14, further comprising:a connection providing power and data to the shoulder when submerged in a fluid from operators outside the fluid. 18. The apparatus of claim 14, further comprising:a float positioned on the back arm away from the shoulder so as to counter torque on the shoulder from the back arm and the front arm when immersed in water.
