RTP - Robotic Test Platform (drone/robot)

In collaboration with a friend, we're developing an innovative robotic test platform (RTP) for experimenting with electronic circuits and programs. Initially, our idea involved a small wooden platform with transmission motors, but it evolved into a larger autonomous robot capable of driving outdoors. The robot will be equipped with sensors, cameras, and a GPS receiver, allowing users to set up traveling routes via computer, tablet, or smartphone. After researching standard hardware components, motors, electronics, and batteries, we designed the robot using SolidWorks. It features a sheet metal frame and is powered by two 500W 24V electric bike motors and six 12V 7Ah SLA batteries. The speed controllers support PWM input signals and RS232 connections, making them ideal for our project. To test the drive train, we created a temporary setup that allowed us to evaluate the motors, speed controllers, and transmission. A video showcases the initial tests, which revealed an issue with one of the shafts due to misaligned gears. After fixing this problem and repositioning some gears, the system functioned smoothly. Using access to a well-equipped workshop, we built the robot's frame in just a weekend. Once assembled, we test-fitted all components, allowing us to take the robot for its first drive. Batteries and electronics were temporarily mounted on top of the machine for easy adjustments. The robot performed well during this initial test run. Following disassembly, we sandblasted most components to remove sharp edges and provide a suitable surface for powder coating. We chose a dark grey textured finish that looked fantastic with the lighter grey and yellow accents. Reassembling the robot, we added protective panels to shield internal components from dirt, sand, and water.

This project is a collaborative effort with Stef van Itterzon, who also maintains a website (www.svitterzon.nl) showcasing his work.
