Everyone is affordable DIY-Based on Arduino Design Supervalent Spider Robot

This video is to describe a portable four-legged spider-like robot, design is cheap, and you can walk. It is easy to make and easy to modify and expand. I think that one of our recess around us is that research pedestrian robots is a time-consuming, arduous and very expensive project, which is traditionally limited to secret military laboratories. You need a large room with a heavy machine to hang the robot to prevent the robot to drop, you need a large number of hydraulic actuators and a pump to provide power, and requires a powerful computer complex sensor and complex Algorithm, etc. This is the case so far. Even from the toolkit to build a simple six-foot, it is just a simple toy, but you may lose hundreds of dollars. This is also no wonder that we have not progress in this regard. This situation must be changed. If we put a walking robot on each high school table, let them try to crack and try the most crazy ideas, so soon soonre before, someone will think of a lot of cool skills to solve the robot's leg sports. . We have a lot of points to be cut. In addition, those high school students may continue their experiments and research, and graduated from robotics and builds we have always wanted robots or other things. This is my current plan. In order to solve the problem of problems that humans need to solve the problem, I am studying a robot suitable as a base for the experimental robot's gait and related issues. Unfortunately, that robot has a lot of problems. Unlike all portable robots, it is powered by 2S lithium batteries and has a buck converter that minus voltage to 5V. That small buck converter can only work for a few minutes, and then the current drawn at the server began to shut down. Therefore, I decided to open this robot to replace the power supply with a more standard setting (without any voltage stability), add the battery charging circuit, and replace the server. This is the USB port of the battery charging circuit: The replacement servo system has been applied to black coating, waiting for dry to dry brush: Finally, the entire robot is very cool and by the gentlemen: Circuit design instance Of course, you need to resume the pins in your code, but this should be easy. It even has a voltage divider for monitoring the battery. Oh, right, don't use the alkaline battery on the picture. Use the four-axis aircraft or LIPO in the old phone. Be Source HackADAY
