Connect the gadget A to the ‘coffin’ B .

A

B
A is a prototype of Lunokhod , the Soviet Lunar Rover . B shows the Sarcophagus , the protective concrete structure built over the wrecked Chernobyl reactor .
Immediately after the Chernobyl Disaster , remote controlled bulldozers were called in to assist in the recovery process . But , these weighed dozens of tons and couldnt operate on the partially collapsed roof of the reactor. As a result , the designers of the Lunokhod were called in to produce a rover which was light enough to operate on the roof . The original Lunokhod moon rovers used nuclear decay heatsources for internal rack climate control and hence their electronic systems were already hardened to resist radiation. 2 such rovers were eventually built and were of immense help in clearing the debris .
Only Rajith Ravi earned the title of ‘moonwalker’ . Splendid job , buddy !

A- WALL-E gadget ?????(Waste Allocation Load Lifter Earth Class)

Pixar studied Chernobyl and the city of Sofia to create the ruined world for Wall E
A:Soviet Moonrover Lunokhod

such rovers were delivered to the Chernobyl accident zone and proved useful for clearing debris, where human labourers or military vehicles cannot be implemented to clear the debris.
