Abstract
This paper presents a novel optimal control algorithm for coordinated force and motion control of multi rover robotics system with mecanum wheels while manipulating a common payload. Such a system with kinematical rolling conditions lead to non-holonomic constraints. The proposed control algorithm focuses on the minimization of joint torques, the rover-mecanum wheel moments as well as the contact force / moments made with the payload. A quadratic cost function in terms of the joint torques, the wheel moments and the contact forces and moments are minimized to overcome the so called joint torque saturation problem commonly seen while manipulating a common payload and also to provide an optimum solution for such an underdetermined system with non-holonomic constraints Furthermore, the proposed control algorithm provides an on-line trajectory generation capability while manipulating a common payload for both the rovers and the arms simultaneously. The computer simulation results show that the control algorithm works efficiently and the minimum joint torques, and the contact forces and moments can be obtained while the end-effectors are manipulating and tracking a desired payload trajectory.

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
