[Markus_p] has already finished one really successful 3D printed tracked robot build. Now he’s finished a second one using standard motors and incorporating what he learned from the first. The results are pretty impressive and you can see a video demo of the beast, below.
Most of the robot is PLA, although there are some parts that use PETG and flex plastic. There is an infrared-capable camera up front and another regular camera on the rear. All the electronics are pretty much off the shelf modules like an FPV transmitter and an electronic controller for the motors. There’s a servo to tilt the camera, as you can see in the second video.
The body fits together using nuts and magnets. The robot in the video takes a good beating and doesn’t seem to fall apart so it must be sufficient. What appealed to us was the size of the thing. It looks like it would be trivially easy to mount some processing power inside or on top of the rover and it could make a great motion base for a more sophisticated robot.
Looking for a tracked rover you can drive around on the desktop? [Markus_p] has one of those too!
