EVALUATION RECORD

SONIC v1.1

LAFAN1 × G1 29DoF · Ideal proprioception · no global position

Evaluated by MotionChallenge using the shared protocol.

Results

26 / 40motions passedCompletion 81.43%

Success and completion use the first declared failure. MPBPE measures position errors over the benchmark’s declared body origins, with three alignments over two time ranges.

116.97108.542035.9244.6140.821540.55

Entire-motion errors include every frame through the endpoint, including post-failure states. The other range ends at the first failing sample, including that sample.
