Lesson notes
Key points
- Sense-plan-act: Robots sense the world, plan a response, then act.
- Actuators: Motors and pistons turn energy into motion at joints.
- Joints: Revolute joints rotate; prismatic joints slide in a line.
- Kinematics: Kinematics links joint values to end effector position.
- Sensors: Encoders, IMUs and LiDAR tell the robot its state.
- Control: Controllers use feedback to shrink error between target and actual.
Takeaway: Sense, plan, act: sensors, kinematics, actuators and control.
Quick check: What type of joint produces straight-line sliding motion?
- Revolute joint
- Spherical joint
- Prismatic joint
Prismatic joints translate along an axis; revolute joints rotate.
