The Greyhound

thingiverse

Finally, I completed my one-year project which resulted in a lightweight greyhound robot that can be controlled using an Arduino board and 8 servos. This model is open for improvements to make it walk even more smoothly. Along with the robot, you'll also receive a basic program to kickstart your journey. Check out this video [here](http://www.youtube.com/watch?v=aDwTdbP_TBU) for a demo of the greyhound in action. Stay tuned for updates! On April 14th, we introduced the Greyhound Programming Stand that you can download from [here](http://www.thingiverse.com/thing:73893). If you create an exceptional program for this robot, I'll be more than happy to feature it on my website with your name as the author. To build the greyhound, here are the necessary components: 1 x Arduino Uno 8 x Servos (I used TowerPro MG90s) 1 x UBEC Regulator (XQ 50 Pichler was my choice) 1 x Lipo Accu (either a 2S or 3S) 17 x M3x10 screws 5 x M3x30 screws 13 x M3 nuts You'll also need glue or use your 3D printer to plastic weld the pieces together. Don't forget to grab some wires and connectors, following the schematics provided. I added a switch for turning off the power supply to the servos. For assembly instructions, download the 'Assembly - The Greyhound.PDF' document. Start by attaching the servo horns in the right positions on each part. Make sure you follow the instructions in the PDF carefully, especially when mounting the servo horns on the lower legs. Assemble the left body and its front and back legs. Use the correct angles for each servo to ensure proper functioning. Repeat the assembly process for the right side, but replace a few parts: _Neck, _HeadSpacer, _BodySpacer35mm, and _BodySpacer31mm. Once you have both halves assembled, insert the Arduino and connect the cables as shown in the provided picture. Use these pins for servo connection: 1 - Front Right Upperleg, 2 - Front Right Lowerleg, 3 - Front Left Upperleg, 4 - Front Left Lowerleg, 5 - Back Right Upperleg, 6 - Back Right Lowerleg, 7 - Back Left Upperleg, and 8 - Back Left Lowerleg. Finally, mount all the parts together to complete your greyhound robot. To use the provided programs (STAND.INO for software calibration and WALK4.INO for walking), download them and follow the instructions. If you find any issues or have improvements, please let me know. I'm eager to see your creations and programs! Good luck with your greyhound robot project!
