Abstract
A robot capable of operating in active pipelines would be of great commercial and industrial benefit. This paper outlines the requirements for such a robot and considers the advantages and disadvantages of existing systems. A new design for an inchworm robot based on the Gough-Stewart parallel platform is presented. The use of inchworm locomotion keeps the control system relatively simple, whilst the use of the Gough-Stewart platform allows the robot to benefit from the accuracy, rigidity and speed of parallel robots and provides a flexible base for any manipulators the robot may use. The design aims to provide minimal resistance to fluid flow by providing a low frontal area and by distributing the body of the robot towards the edge of the pipe, where the flow is slowest. An analysis of the robot’s degrees of freedom, a derivation of the robot’s inverse kinematics equations, and a static force analysis are presented along with a description of the robot’s proposed locomotion algorithm.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
