Project Domain
Robot Arms
Articulated motion, grip mechanics, and coordinated servo control.
Systems Students Explore
Robot arm projects challenge students to understand how joints, linkages, and servos work together to create precise, repeatable motion. Students learn how mechanical advantage, torque, and range of motion interact.
Servo Kinematics
Positioning multiple joints to reach target locations
Grip Mechanisms
Designing end-effectors that can grasp and release objects
Structural Load
Building arms that support weight without wobble or sag
Control Sequences
Programming smooth, coordinated multi-axis movements
Example Projects
Projects progress in complexity across grade bands:
- Single-axis grabber that opens and closes with a button
- 3-axis arm controlled by joystick or potentiometers
- Programmable pick-and-place arm with saved positions
- Autonomous sorting arm using color or distance sensors
Evidence Outputs
Students produce tangible evidence of their engineering learning:
- Working prototypes demonstrating grip and reach capabilities
- Photos documenting the build process and iterations
- Annotated sketches showing joint placement and range of motion
- Testing reports comparing different grip designs or arm configurations
