Designing a Compact Gearbox for Robotics

One of my most rewarding projects involved designing a compact gearbox for a small robotic arm. The goal was to create a gearbox that could fit within limited space while providing enough torque and speed control for precise arm movements.

Project Goals and Challenges

• Fit the gearbox within a 10 cm cube

• Achieve a torque output of at least 15 Nm

• Minimize noise and wear during operation

• Ensure easy assembly and maintenance

  
  

Approach and Solutions

I started by selecting the right gear types. After evaluating spur, helical, and planetary gears, I chose a planetary gear system for its compactness and efficiency. Using CAD software, I modeled the gearbox components, paying close attention to gear tooth profiles and clearances.

To reduce noise, I specified materials with good damping properties and applied surface treatments to gears. I also designed the housing to include lubrication channels for smooth operation.

Results

The final gearbox met all specifications. It fit perfectly within the robotic arm, delivered the required torque, and operated quietly during testing. This project sharpened my skills in gear design, CAD modeling, and material selection.

Developing a Heat Exchanger Prototype

Thermal management is critical in many mechanical systems. I worked on a prototype heat exchanger designed to improve cooling efficiency in small engines.

Objectives

• Increase heat transfer efficiency by 20%

• Reduce weight compared to existing models

• Use cost-effective manufacturing methods

  
  

Design Process

I began by analyzing the heat transfer requirements and flow rates. Using simulation software, I tested different fin geometries and materials. Aluminum was chosen for its lightweight and thermal conductivity.

The prototype featured a compact fin design that maximized surface area without adding bulk. I also incorporated modular sections to allow easy scaling for different engine sizes.

Testing and Outcomes

The prototype was tested under controlled conditions. It showed a 22% improvement in heat transfer efficiency and weighed 15% less than the previous model. This project enhanced my understanding of thermal dynamics and prototype testing.

Building an Automated Conveyor System

Automation is transforming manufacturing, and I contributed by designing an automated conveyor system for a packaging line.

Project Requirements

• Handle packages up to 5 kg

• Operate continuously with minimal downtime

• Integrate sensors for package detection and sorting

  
  

Design Highlights

I designed the conveyor frame using lightweight steel for durability. The belt system was powered by a variable speed motor controlled through a programmable logic controller (PLC).

Sensors were placed at key points to detect package presence and size. The system could automatically divert packages based on predefined criteria.

Implementation and Benefits

The conveyor system improved packaging speed by 30% and reduced manual sorting errors. This project gave me hands-on experience with automation components and control systems.

Creating a Sustainable Water Pump

Sustainability is a growing concern in engineering. I designed a water pump powered by renewable energy sources for rural irrigation.

Design Goals

• Use solar or wind energy as power source

• Ensure reliable operation with minimal maintenance

• Keep costs affordable for small-scale farmers

  
  

Engineering Solutions

The pump uses a direct-drive mechanism connected to a solar panel or wind turbine. I selected corrosion-resistant materials to withstand outdoor conditions.

The design includes a simple valve system to prevent backflow and maintain pressure. I also optimized the impeller shape for maximum water flow with low power input.

Impact and Feedback

The pump prototype was tested in a rural community. It provided consistent irrigation without fuel costs, improving crop yields. This project deepened my commitment to sustainable engineering solutions.
