July UFO Robot Walker

cults3d

For the July UFO 3D Printing Mystery Box, Bryan Vines and I designed a bipedal walking robot that works seamlessly with the included gearmotor and battery pack. Thanks to Bryan for making some crucial tweaks to the files, which have been included in his modified STL's zip file. To assemble the robot, start by slipping the lower spacers onto the arms of the gearmotor. Next, slide the lower gear onto the arms of the gearmotor and secure it with a washer and an M2 6mm screw. On the opposite side, the lower gear should be turned 180 degrees to ensure proper alignment. Secure the middle gear and top gear onto the gear holder using a washer and an M2 6mm screw. Then, angle the gear holder towards the back as shown in the photo, fitting the gear teeth of the middle gear with the lower gear attached to the gearmotor. Make sure the lower gear and top gear outer "axles" are aligned in the same direction and hot-glue the gear holder to the gearmotor. Secure the leg to the lower and upper gear "axles" using a washer and an M2 6mm screw. Insert 2 AAA batteries into the battery holder and glue it to the back of the gearmotor, taking care not to seal the slideout cover shut. Connect the red wire of the gearmotor to the red wire of the battery holder, and the black wire to the black wire. Attach the feet to the bottom of the legs, ensuring a tight fit that keeps them in place on their own. Turn the gearmotors so both feet are level with each other. If desired, glue the feet to the legs. Flip the switch on the battery pack to the "on" position and place the robot on a flat surface. I hope everyone who received the July UFO had a blast this month with their robot!
