It’s likely you’ve seen the famous Boston Dynamics quadruped robots that can hurdle over obstacles and carry heavy payloads. Robot maker and hobbyist, Max, recently shared on his robotics blog about his latest robotics project aimed at making a cheap and easy-to-build quadruped.
Max explains on his blog.
“For a long time I have been fascinated by walking robots, especially the awesome creations from Boston Dynamics. Their 26km/h wildcat made the headlines last year. But quadruped robots like that are something you can’t build by yourself. They require a huge amount of money and programming skills. Or do they?”Using nothing but hobby electronics and some precision-cut parts, Max was able to construct a walking quadruped robot closely resembling one of Boston Dynamics’ robots. Here’s a couple of videos of the ‘baby quadruped’ learning how to move around for the first time.
The robot's chassis is comprised of cut acrylic designed to look like Boston Dynamics' LS3 robot. You can view some photos of that robot here. Max decided to use custom-cut 5mm acrylic glass for the robot's main body material. To bring all the pieces together, threaded nuts and bolts were used alongside the plastic pieces. You can see that 3 servos make up each leg and are mounted to the plastic plates. The electronics are embedded on top in the middle of the foam bumpers. Below is a photo showing just how small this robot is.
The internals of the robot include hobby servos (around $40 for all of them), an Arduino MEGA, a Bluetooth module, a rechargeable battery, and an ultrasonic sensor. The Arduino MEGA is capable of controlling all 12 servos while the Bluetooth module allows the robot to be controlled via an Android app. The sensor on the front acts as the robot's "eyes."
This is definitely one of the most unique and original homemade robots I've seen in a while. Perhaps you have your own robot project you'd like to share? Email us at contact[at]simplebotics.com to share your robotics project.
