SimulatorWe derive why three weeks of friction-coefficient tuning was doomed from the start — in a skid-steer vehicle's turning-ability ratio, both the friction coefficient and the weight cancel out, leaving only contact geometry. With measured data, plus two hard-earned lessons about trusting simulation instrumentation.
SimulatorNo physics engine has a native "track" primitive. We share how we modelled a tracked skid-steer robot in Isaac Sim — the failure of a 46-link articulated track, a 4-contact model that turned "perfectly" and was wrong precisely because of it, and the measured 12-contact distributed virtual-wheel model we use today.
ControlIn the domain of 1kHz real-time motor control that LLMs cannot replace, we introduce WIM's approach to replacing traditional PID/ADRC manual tuning with reinforcement learning (RL).
Embedded/Real-timeWe measured whether atomic memory ordering could be a performance bottleneck in a 1kHz RT loop on Jetson Orin (Cortex-A78AE). On AArch64, the cost of seq_cst is virtually identical to release/acquire, and the total cost of 25 atomic operations is less than 0.01% of the 1ms budget.
Vision/InferenceAn exploration of how template matching technology in computer vision has evolved from pixel-based methods through SIFT/ORB to SuperPoint/SuperGlue. Covers the principles, limitations, and use-case recommendations for each approach.
ControlThis article explains the CiA402 profile, the motor control standard for industrial robots based on EtherCAT and CANopen. It covers the state machine, Controlword/Statusword bit structures, and operation modes with practical examples.
