Abstract
A planetary gear retrieval system for pulling a sled at a constant velocity along an interior of a pipe. The system includes a network of gears, one of the gears powered by a gear motor, which is in operable communication with a variable speed microcontroller. A chain is threaded through the network of gears and an end of the chain is connected to the sled.

A planetary gear retrieval system for pulling a sled at a constant rate along an interior of a pipe, comprising:
- a network of gears including a first gear, a second gear, and a third gear, the first gear being powered by a gear motor;
- a chain threaded through the first, second, and third gears, the chain having an end attachable to a sled to be pulled by the planetary gear retrieval system.
A planetary gear retrieval system for pulling a sled at a constant rate along an interior of a pipe, comprising:
- a stand including
- a plurality of legs;
- a plurality of supports extending between the legs at a bottom of the stand;
- and
- a plate supported by the legs;
- a gear motor supported by the plate;
- a network of gears provided on the stand, including a first gear powered by the gear motor, a second gear, and a third gear;
- and a chain threaded through the first, second, and third gears, the chain having an end attachable to a sled to be pulled by the planetary gear retrieval system.
