Regular scorpions have eight legs, together with a definite stinging tail. This little mechanical ScorPIon robotic by Hannu Hell options solely 4 legs, nevertheless it does have a distinguished tail, used right here for taking video as a substitute of stinging.

The robotic is actually cute, and its “scorPIon” moniker is a intelligent play on its Raspberry Pi Zero W controller. The Pi provides it the power to interface with a wise machine through Bluetooth or Wi-Fi for management, and it will probably stream video from its tail for FPV capabilities. It makes use of a devoted UPS battery provide for the Raspberry Pi, whereas servos are powered by a 7.4 V 1300mAH LiPo Battery. This dual-battery setup is considerably optionally available, nevertheless it mitigates just a few hassles.

For motion, every leg options two servos/levels of freedom, enabling the ScorPIon to stroll and switch in any path, and even dance. The tail additionally options two servos, permitting for exact digicam positioning, whereas producing a delightful motion when changes are made.

The Pi calculates leg actions primarily based on inverse kinematics and secure three-legged positions. Direct servo interface is facilitated by a 16-channel 12-bit PCA9685 PWM module that communicates through I2C.

The robotic’s mechanical elements are 3D-printed, together with the legs, base, and tail. There’s even a pleasant cowl that goes over the Pi {hardware} to make it look a bit extra completed/cute. Code and 3D information are accessible on GitHub, and the construct appears like a enjoyable and approachable strolling robotic undertaking!
