Inside the model is an N20 gearmotor with a 55mm M3 shaft e.g. https://www.aliexpress.com/item/32956961754.html -- I chose the 400RPM version. Running off a 9V battery, I guess it's spinning about 300RPM, which is plenty. The motor slides sideways...

Search online for "37mm 12v gearmotor" to find suitable suppliers at affordable prices. Opt for slower motor speeds if you want more realism and endurance. Note that the motors shown in the video are not the same as the recommended ones; I used...

Also, there is a minor amount of soldering involved in the electronics (six connections necessary to wire up the three DC gearmotors). I recommend learning to solder before trying it out on this project. I shouldn't have to say this to people who...

Inside the model is an N20 gearmotor with a 55mm M3 shaft. This motor spins at about 300RPM when running off a 9V battery. The motor slides sideways into the mount (see the yellow test print of the mount) which is then screwed to the engine mount...

If you use RC servos, or gearmotors, just ignore the upper motor holes or set the motor sizes to 0. Honestly, you probably don't need this script then. A good motor / controller / firmware package for a robot like this can be found here:...

Other than 3d printed parts the catapult uses one hobby gearmotor, rubber elastic bands, and M3 screws.In regards to screw length I used two 8mm M3 screws, and four 25mm M3 screws. Since these are the sizes I had available this is what I used;...

The small gearmotor used can operate on 24v, but stalls more easily without drawing too much current when less voltage is applied. The motor is driven by a tiny 1A H-bridge. The FFB controller was designed by me back in 2015 and has DB9 plugs on the...

3- I HAVE A METHOD FOR KEEPING THE GEARMOTORS, SOLENOIDS, ETC. WARM AT NIGHT. IT REQUIRES NO ADDITIONAL HEATING ELEMENTS, INSULATION OR WIRES. THIS SAVES A LOT OF WEIGHT. DETAILS ARE REQUESTABLE. 4- ROBOTIC ARM; THE ILLUSTRATION IS GENERIC. ITS...

The motor is a commonly available 6V 100 rpm N20 gearmotor powered by a 150 mah lipo. The batteries were purcased from Banggood and came with a charger and the small jumper cables. You need to use one of the charging cables to hook the battery to the...

You can access the connector for the battery to recharge it by removing the back of the boiler which is held on by a screw. Parts: 6V 100 rpm N20 gearmotor 1/8 inch or 3mm dia X 32 mm long rod. I used 1/8 inch brass brazing rod.<br/> 2mm X 8mm self...

In the ordinary way this would be a hindrance but here we take advantage of the backlash to create a stomping gait.AlternativeIf you have difficulty with these instructions an alternative is available on:...

A kit like this should do it. Arm servo is an MG 996R (common import servo), like this one. Intake motors on the arm are N20 300rpm 6V gearmotors like these. Wheels press on and are locked with M3 set screws like these.</p> <p>The "spatula" at the...

I also had to get m1.6-0.35mm screws to mount the gearmotor. Since the only ones I could get quickly at a reasonable price were 6mm long, that's what I designed the gantry for, so that they can be snug without interfering with the gears of the gear...

I'll leave it to the purist to remix the model so all the valves are in the correct positions. Extrusion of the blue stopped midway through the print of the base; I have other things to do, so I can't be bothered redoing that. Inside the model is an...

It has two N20 gearmotors driven by a L9110S dual H bridge. An Arduino Pro Mini controls the motors with feedback from a cam and switch on each leg. The Arduino uses the feedback to keep the motors in sync. The Arduino receives commands from an IR...

If you print the gear for the motor (gearMotor.stl) it's a good idea to use for glue (like cyanoacrylate, aka crazy glue). Just press fit is not good enough when the motor get hot. If you buy the motor with the gear already installed make sure the...
