[Joel Miller] wants to get his daughters into electronics early (his oldest is only 3), so he’s decided to foray into the wonderful world of robotics as a fun way to get them interested. As bonus to us and all other would-be robotics enthusiasts out there, he’s keeping track of the project on his blog!
He started by sketching out some ideas about what he wanted his robot to be capable of — it should be able to move around, be remote controlled, have sensors for experiments, and even have some personality — expression capable eyes maybe? Oh and it should be able to automatically charge itself, and have tank treads!
It’s been a few weeks since he started scheming up ideas… and he already has a prototype complete! Talk about a productive father! He decided to try 3D printing a continuous tank tread using ABS, but unfortunately it was a bit too stiff, so he’s opted to use a tried and true Lego system instead — although maybe he should try printing in two materials, like we just saw with the FlexyDualie extruder!
The chassis of the robot is also 3D printed, with threaded brass inserts since he knows it’s going to be taken apart and put back together many times. Two RC servos are installed as the drive motors, and a piece of polycarbonate sits on top as an easy to modify electronics housing platform. The project is extremely well documented and definitely worth the read if you have time — just take a look at his original sketches!
