When the solar collector had reached seven per cent capacity a signal tickled his brain awake and he commenced system check. With so many of his external functions having failed, and long since been patched out of the feedback web, this didn't take long.
His left 'arm' was almost dead, but the right was holding up, as were the rarely-used, pincer-like helper limbs on his torso. The tracked lower chassis he'd salvaged from a construction site almost a century and a half earlier, and substituted for his legs, was growing temperamental. He would need to find parts soon or it would all be over.
Blind since his natural eyes had died, nonetheless he scanned the area in all directions at once using low powered radar to check for... what? There was never anything bigger than a monkey within his scanning range. Either there was nothing else out there, or it was keeping just ahead of his ability to detect. Switching to his crude, but necessary, visual sensors, he began searching for the clearly identifiable colours which would indicate fruit.
Marking a likely spread of patterns that suggested a fruit tree, he pulled up an infra-red overlay, and, as expected, found it to be heaving with bright, warm life-signs. The frantic contortions, the twining, twisting bumps and bumbles of more than a handful of the heat traces suggested that not a few of the little devils were fornicating. As usual. If he could only grab one of these gormless, little monkeys it would feed his digestion reactor for a month, but it had been years since he had been able to trap game, and in any event, he was now all but resigned to a vegan lifestyle. Even as his systems failed, he grew more resigned to his inevitable death, and more compassionate towards the life around him.
With a lurch he trundled towards the fruit tree, picking up speed at a painfully slow pace until he hit the tree with his reinforced lower front. Heat traces scattered, leaping to neighbouring branches in the canopy, those interrupted in flagrante delicto, no doubt cursing him with their chattering nonsense, but he had no energy to waste right now on his aural circuits. The scoop he'd adapted around his chassis caught the falling fruit, and he set one of his helper claws the task of collecting and feeding these into the bio-reactor.
When all the fallen fruit had been collected, he backed up a dozen yards and took another run at the tree, repeating the harvesting process. But now when he tried to reverse, all he got in return was a grinding clunk, and the slow fade of dying signals from his tracked sub-assembly. He was crippled.
He took an entire minute to let this sink in. An eternity for a dying man. It was over. It might take weeks, months, or even years but he knew his death was as certain as if he had been struck by a meteorite.
Something struck him. Then there was another impact on his armoured shell. Seeing him trapped there, the monkeys had returned to their tree and, emboldened by his stillness, were pelting him with fruit. The beautiful little monsters were unwittingly doing him an enormous favour, buying him time to come up with a solution. And if there was a way out of this, a way to keep on living, then he, the last civilized being on this forsaken planet, would find it.
Long-Leap Scholar plucked another gawak fruit from the branch and, after a brief moral wrestling match, took a bite from it, as he mounted his lover, Tail-Sheen Joker, for the third time that morning. He dropped the rest of the morsel to the organic-metal hybrid below, as he slipped a thought into his paramour's mind. "I feel so sorry for it. Its people took the wrong road so very long ago."
