NASA and other space agencies around the world have been building probes to explore other planets for decades. One thing these rovers have in common is that they are very expensive to build, often up to millions of dollars. During the popularity of the new crown, space enthusiasts who want a new electronic project should take a look at the exomy Rover launched by the European Space Agency (ESA). < / P > < p > although the exomy rover is designed to appeal to all interested in space, it is based on the ESA’s Rosalind Franklin Mars rover, formerly known as the ExoMars Rover. Exomy is a DIY project that anyone can build, featuring a three-tier suspension design and six wheels. < / P > < p > each of the six wheels can be turned, making the rover highly flexible. The robot is not cheap to make, ranging from 250 to 500 euros. For those who want to work on a project, the instructions are posted on GitHub. The builder needs a 3D printer to complete the project. < / P > < p > exomy’s “brain” is raspberry pie, and the software stack is configured for remote control. However, the robot operating system will allow those who want to have their own Rover to build some functions. The size of the finished equipment is 300 × 390 × 420 mm and the weight is 2.5 kg. Every time you charge the battery, it can run for three hours. The rover is 100% open source. < / P > < p > exomy is not the first DIY Rover to use 3D printing and electronic technology to create cool things. There is also a larger Rover project on the Internet based on the rover curiosity. The Rosalind Franklin Mars probe was supposed to go to Mars this year. However, the popularity of the new crown caused the probe to miss the launch window and was delayed until next year. Apple extends AppleCare + purchase period: users can decide within 60 days
