Pain Points of Spider Robots

1. Limited Workspace

• Beschreibung: Its working envelope is relatively small and dome-shaped due to the parallel-arm structure.
• Pain Point: Unsuitable for long-distance movement; ideal only for compact work areas.

2. Very Low Payload Capacity

• Beschreibung: Designed for speed, with lightweight components limiting load capacity.
• Pain Point: Typically handles only a few grams to a few hundred grams.

3. Restricted End-Effector Orientation

• Beschreibung: The moving platform has limited ability to independently control tool orientation during motion.
• Pain Point: Not ideal for tasks requiring complex tool reorientation, like intricate screwdriving.

4. Fixed Mounting Configuration

• Beschreibung: Typically ceiling-mounted, with a fixed work zone after installation.
• Pain Point: Reduces layout flexibility compared to floor-mounted robots on tracks.

5. More Complex Programming and Tuning

• Beschreibung: Relies on complex inverse kinematics. Deep optimization requires specialized expertise.
• Pain Point: Higher technical barrier for programming and debugging.

6. Relatively High Cost

• Beschreibung: Requires multiple high-precision servos and specialized controllers, leading to higher unit cost.
• Pain Point: High initial investment threshold.

In summary, the pain points stem from its inherent design trade-offs: it sacrifices workspace, payload, and orientation flexibility to achieve unparalleled speed, precision, and dynamic performance. It is a specialist, not a generalist.
