Design Process

Problem Statement

Draft: Develop a remotely controlled robot that uses an extending arm and claw to pick up, move, and place a payload in a simulated exploration environment.

Problem Statement

Available FTC parts and tools.

Time remaining before PDR.

Available motor and battery capacity.

Requirements

Controlled driving and stopping.

Controlled arm extension.

Claw opening and closing.

Payload pickup and placement.

Stability while handling the payload..

Brainstorming 1

Our first idea was an elevator-style lift to raise and lower the claw. We decided it would take up too much space and be too difficult to build with our available time and parts, so we started considering an extending arm instead.

Prior Experience and Design Basis

Our initial design choices were based on our experience building and working on FRC robots, particularly with mechanisms, assembly, and control systems. External research has not yet been completed.

Brainstorming 2

After reconsidering the elevator lift, we chose to move forward with an extending arm and claw. We felt this would fit the robot better and be more manageable to build using our available parts and FRC experience.

Top 3 Concept Diagrams

Fixed-length pivoting arm

A. Fixed-Length Pivoting Arm

A simpler arm that pivots up and down but cannot extend, limiting its reach.

Reference images; not our prototype.

Pivoting extending arm

B. Pivoting Extending Arm

The arm pivots up and down and extends outward, with a claw at the end for gripping and placing the payload.

Vertical lift

C.

A vertical lift raises and lowers the claw.
