Lesson notes
Key points
- Every / Encoder: Every stands for encoder, which measures joint angle or wheel rotation.
- Elephant / IMU: Elephant's inertial sense recalls the IMU, measuring acceleration and angular rate.
- Feels / Force/torque: Feels means force-torque sensing, letting a gripper know how hard it squeezes.
- Pressure / Proximity: Pressure reminds you of proximity sensors, detecting nearby objects without contact.
- Very / Vision: Very is vision: cameras that give rich data about the surroundings.
- Lightly / LiDAR: Lightly is LiDAR, measuring distance by timing reflected laser pulses.
Takeaway: Every Elephant Feels Pressure Very Lightly: six key robot sensors.
Quick check: Which sensor measures distance by timing reflected laser pulses?
- Encoder
- LiDAR
- IMU
LiDAR uses time of flight of laser light to compute distance.
