robothut Posted May 7, 2019 Share Posted May 7, 2019 I would love to have feedback on the parts colors, the flashing light effects and if the arms should move together or alternate. And if there is any interest in a build of this bot. Link to comment Share on other sites More sharing options...
robothut Posted May 7, 2019 Author Share Posted May 7, 2019 Lets start the build . Start with the gearbox. It prints with out supports and a lever micro switch can be installed to control the flashing light effects. Link to comment Share on other sites More sharing options...
robothut Posted May 7, 2019 Author Share Posted May 7, 2019 Next prep the motor with the flasher cam and drive gear. and insert in the gear box. No glue or screws required. Link to comment Share on other sites More sharing options...
robothut Posted May 7, 2019 Author Share Posted May 7, 2019 Now prep the antenna drive disc and shaft. In my case I have a few threaded shafts in the parts boxes but any hobby rod stock could be used and glued to the drive disc. Insert the shaft and drive disc unit in the gear box at this time.

robothut Posted May 7, 2019 Author Share Posted May 7, 2019 Print out the drive shaft's, gears, bushing , spacers and crank parts. Link to comment Share on other sites More sharing options...
robothut Posted May 7, 2019 Author Share Posted May 7, 2019 glue one of the small crank units to a axle, then slide on the bushing. Link to comment Share on other sites More sharing options...
robothut Posted May 7, 2019 Author Share Posted May 7, 2019 Slide in the crank, axle, bushing unit in to the gear box. Put on the spacer unit as you slide in the axle. The spacer has a place for the rubber O ring that will be used to drive the antenna drive disc. Also put on one of the large gears. Push the axle all the way threw and then slide on the bushing part and glue on the small crank. In this case glue on the small crank in the same direction as the Left side.

robothut Posted May 7, 2019 Author Share Posted May 7, 2019 Now do the same thing for the lower axle unit. The spacer is different as it does not drive a antenna disk. Put the large flat part of the spacer to the left side. Put in the large gear. Now before you put on the bushing and glue on the small crank on the right side you need to move the large gear to the correct position. The easiest way to do this is to just snap on the large crank parts on to the ends of the small cranks. This gives you more to look at to line everything up. With the bushing on the right side not installed you can jump teeth on the large gear until it is in the same position as the top cranks. It is best to have rotated the top cranks to a vertical or horizontal position so you can really see things line up. If you are off 1 tooth on this step there is a good chance the legs will bind up when you try to test run the gear box. Once you have it looking right slide in the bushing and glue on the small crank. Everything will be locked in place. If you did it wrong you will have to break or cut the axle and print new parts for the lower axle unit. Link to comment Share on other sites More sharing options...
robothut Posted May 7, 2019 Author Share Posted May 7, 2019 At this point you should test run the unit to make sure everything is OK. Start with just the 2 inside legs. If they run smoothly then you can glue on the larger outside cams. Link to comment Share on other sites More sharing options...
robothut Posted May 7, 2019 Author Share Posted May 7, 2019 We can prep the arms and antenna parts. The arms can be screwed together if you want them to bend, or glued in to postion. Just remember you have to make a left and right arms so when glueing keep that in mind. The arm levers that move the arms get glued into place . Make sure they angle back. These are hex shafts so the angle will be set automatically. The two antenna parts get glued together as well. Just some prep work to get out of the way.

robothut Posted May 7, 2019 Author Share Posted May 7, 2019 New we can insert the gear box unit into the body front. There is a place for a screw in the bottom to hold it together once you get it in place. It is a snug fit, so make sure it is all the way in and down.

robothut Posted May 7, 2019 Author Share Posted May 7, 2019 Now glue in the translucent face part and the ears. There is a motor cap that glues on to the body base as well. Link to comment Share on other sites More sharing options...
robothut Posted May 7, 2019 Author Share Posted May 7, 2019 Things should look like this at this point. Now the two translucent red body parts can be glued in or you can add LEDs to them. The tricky part of adding LED's to them is inside the LED wires will pass very close to the drive gears on the right side so be carful to rout them out of the way, or glue them out of the way. I find it best to add the LEDs to the translucent parts first, then fish the wires threw the holes and then glue the translucent parts and leds on to the body.

robothut Posted May 7, 2019 Author Share Posted May 7, 2019 close up of the antenna drive and the led wires in the gear box. Link to comment Share on other sites More sharing options...
robothut Posted May 7, 2019 Author Share Posted May 7, 2019 The body back can have the 2 AA battery holder glued in place. There is a channel on the inside of the body back that the battery wires can be run threw. it is kind of tight but they will fit. The switch can be installed as well. In this case I used a ON-OFF-ON slide switch so that I could have Forward Stop and Reverse. I wont go into the wiring of this function or how to get proper power to the LED's in a set up like this.
