This is an easy to assemble toy car made using lots of high-tech tools. Once you 3D print, and laser cut your parts, the rest can be zip tied and bolted together in minutes. I was initially planning on making more of a hot rod. However, thanks to the slow speed of the servos, it turned out to be more of a cruiser. This vehicle has a slow smooth ride, which makes it the perfect motorized platform for all kinds of applications. For instance, it makes a great camera dolly (for silent films and music videos), and a suitable robot base. Nonetheless, it was a fun exercise in state-of-the-art personal fabrication.






I made it at TechShop.

(x1) 1/4" x 2" stainless Steel rod
(x1) 4 x AA battery holder
(x4) AA batteries
(x12) 4" zip ties

Sanding and staining will ensure your cruiser's frame is more durable and has a longer lifespan.

Sand both sides of your wooden bracket and wipe them off.

Coat one side with wood stain. Wait for it to dry, sand it lightly, and then coat it again.

When the first side is dry, repeat on the opposite side.

Step 3: Drill

Grab one of the servo motors. Widen the outermost hole in each corner of the servo's horn with a 1/8" drill bit.

Repeat on the other servo.

Step 4: Zip tie

Place the pivots onto each end of the metal rod.

Slip the wheel into front fork of the laser cut bracket and zip tie the pivots firmly in place.

If you enlarge this project could it become a motorized skateboard? If so do you think it would have a chance of holding a 90 lbs child?.

This is very similar to my things but my one has two wheels at the front one at the back like the Morrigan. DO you have any other cars like this and does that car have a switch.

Ps its worth looking at my ones a the you will see how similar they are

It looks pretty useful. Lets see some simple bots based off this platform!
does it even matter if it flips?
randofo (author)  thecrazymagnetman2 years ago
If it flips, it goes backwards
cool
Cool project, but from the looks of that video, it is pulling to the left pretty good. Might want to have the front wheel some how a little adjustable to fix that. You could also then set it to slightly turn left or right if you wanted to that way.

a remote would be pretty usefull, like one from a mini rc
