I've been busy working on some new ranking/position methodologies and excited to start sharing some results.
Plot legends:
- X = truncation rate (low = good) - ? = confusion rate (low = good) - blue bars = average completion tokens (low = good) - black diamonds = CI-banded performance (high = good) - cluster squares = models inside this group are equivalent
openai/gpt-oss-120b remains the king in all dimensions of interest: truncation rates, completion lengths and performance. If I had but one complaint it's the reason_effort does not seem to actually work - more on this soon.
Second is a 3-way tie in performance between the Qwen3-235B-2507 we all know and love with an unexpected entrant - ByteDance-Seed/Seed-OSS-36B-Instruct
This is a very capable model and it's reasoning effort controls actually works, but you should absolutely not leave it on the default "unlimited" - enable a sensible limit (4k works well for 8k context length).
Third place is another 3-way tie, this one between Seed-OSS-36B (it straddles the CI boundary between 2nd and 3rd place), Qwen/Qwen3-Next-80B-A3B-Instruct (demonstrating that full attention may be overrated after all and gated is the way to go) and the newly released zai-org/GLM-4.7 which offers excellent across the board performance with some of the shortest reasoning traces I've seen so far.
Robonine are starting work on the next version of the SO ARM 102 manipulator. The version will be open source and agreed upon with @therobotbuilder the creator of the original manipulator.
We are planning to:
- increase positioning accuracy by approximately 2x using Feetech STS 3250 motors - increase working payload from 200g to 300g - increase rigidity using parametric design optimization and stiffer plastic - increase length to 550 mm - increase folding angles - use ISO 9409-1-50-4-M6 mounting standard for the gripper - use a parallel gripper in the default version - update the mounting plate for different camera types, M3 grid with 12.5 mm pitch - add table mounting standard 80x80 M8
The number of degrees of freedom and basic kinematics will remain the same.
Are there other things missing for working with SO ARM 100?
- Any standard inputs/outputs, for example? - Status indicators? - Perhaps some types of mounting for third-party grippers are more preferable? - Anything else?
