Here, you will find descriptions of the various ports, sensors, and connections that enable you to customize and expand CRAWL-e’s capabilities.
Mechanical Design
CRAWL-e features a durable, lightweight aluminum alloy body, an eight-shaped structure, and six independently articulated legs. Its mechanical design provides stability, flexibility, and smooth movement across different terrains.
1. Material Composition
Built from corrosion-resistant, powder-coated Al 5052 aluminum alloy, CRAWL-e offers strength, durability, and easy maintenance while keeping the structure lightweight.
2. Body Design
Its infinity-shaped body, with three legs on each side, provides a stable platform and ample space for electronic components, batteries, and sensors.
3. Leg Alignment
The symmetrical six-leg configuration ensures balanced weight distribution, improved stability, and efficient movement across different surfaces.
4. Degrees of Freedom (DoF)
CRAWL-e features 18 Degrees of Freedom (3 per leg), allowing each leg to extend, bend, and rotate. This enables smooth walking, obstacle navigation, and flexible directional movement.
5. Stability & Weight Management
A balanced centre of gravity and optimized weight distribution help CRAWL-e maintain stability, prevent tipping, and navigate uneven terrain.
CRAWL-e is powered by an ESP32-based electronic system that controls its movements, processes sensor inputs, and enables wireless communication. Its electronics support autonomous operation and remote control.
ESP32 Motherboard
The custom-designed motherboard features an ESP32 microcontroller with:
-
4 GPIO ports for versatile control.
-
4 auxiliary ports for connecting peripherals.
-
6 jumper ports for customization.
-
Wireless connectivity for remote operation and communication.
