My goal for the track link was to be as compact as possible and to connectable with the next link with just one additional part or pin, while being strong enough to be made with a 3D printer. The 11mm pitch was actually defined by the design of the track link. The pitch is 11mm here and I chose the sprocket to have 12 teeth which gave me a pitch diameter of the sprocket of around 42mm. The key dimension here on the sprocket is the pitch because it must match the pitch of the track. The first input parameters for the design were these RC shock absorbers that I had and their dimensions. Let me explain how I came up with robot platform design. “NC Shop Floor Programmer”, CAM for intelligent machining strategies for 3-axis milling and wire EDM in an easy use package.Ĭlick the link below, and you’ll get a special 20% off – so you can start making with the best today! Big thanks to SOLIDWORKS for sponsoring and supporting education content like this. “Visualize Connected”, easily create photo-quality images, animations, interactive web content and more to impress your audience. “xShape”, browser-based freeform CAD that’s easy to use for surface modeling on any device. It’s great for modeling anywhere, anytime, and on any device. “xDesign”, browser-based CAD, you can use it with 3DEXPERIENCE SOLIDWORKS, or on its own. You can store files locally or in the cloud with the 3DEXPERIENCE platform. This offer includes 3DEXPERIENCE SOLIDWORKS Professional, the most in-demand CAD tool within the offer and runs locally on your PC. That allows the vehicle to run smoothly on uneven terrain and climb obstacles while maintaining good contact surface between the tracks and the terrain.įor controlling the 3D printed tank, I’m using a cheap commercial RC Transmitter which sends commands to the platform. With this setup each roadwheel has an individual suspension or a spring and a shock absorber. Or for example, we can make a turret that can fire NERF darts and in combination with the simple but cool LED lighting that I already installed on this platform, we can have quite some fun playing with it.Īs for the suspension, I employed a Christie suspension system that’s been used in tanks for many years. With a robotic arm on top of the platform we can do various tasks like grab and move something, or we can put a camera to it and use it for visual inspection and so on. I hope I will in some of my future videos where I plan install a robotic arm or a turret. The robot platform drives quite well in mud and it’s a pity I didn’t have a chance to test it on snow. The tracks distribute the weight of the vehicle on a larger surface area which provides excellent grip and lowers the odds of getting stuck in soft ground, mud or snow. The best bet for that was to use a continuous tracks system. My goal for this project was to make a versatile platform that can traverse many types of terrains and can be used for various applications.
