The Mars Problem
The InSight Lander tried to drill into Mars but failed. The drill hit a rock, bounced, and got stuck. Why? Because the controller couldn't "feel" the rock density changes in real-time.
The Bangsaen Solution: Sensorless Haptics
We use the motor itself as a sensor. By analyzing high-frequency Current Ripple, we can determine the hardness of the soil millisecond-by-millisecond.
- Soft Soil: High RPM, Low Torque.
- Granite Rock: Instant switch to "Hammer Mode" (High Impulse) within 2ms of contact.
- Result: We cut through rock like a surgeon cuts through tissue. No jamming. No stalling.
