FlexCar With 3D Printed Parts

FlexCar With 3D Printed Parts We still use the PCBA of Flexbot to serve as the electronic part, drawing power from it seamlessly. The metal gear set with built-in motor that I purchased performed exceptionally well. At a compact size of 24 x 12 x 10 MM, FlexCar generates much less noise than expected. However, the only limitation is its relatively small power output. Under a 3V voltage supply, the rotating speed reaches 500r/min without load, and the speed reducing ratio is set at 1/30. Still, I am on the lookout for a gear set with built-in motor that packs more punch. Working Mechanism: With brush motors powering FlexCar, the direction of rotation depends entirely on the electronics controlling them. Changing programs slightly to enable reverse rotation proves challenging, making it difficult to get both front and back wheels moving in one direction simultaneously. To overcome this limitation, I tweaked the software so that the two front wheels can move forward while the two rear wheels move backward. This adjustment allows for easy control via the Flexbot copter App. Renewing the Flexbot App to create a fantastic FlexCar App is also on my agenda. Given its simplicity, I anticipate only minor changes will be required. Apart from the battery, PCBA, and motors, all other components are 3D printed, paving the way for even cooler shell and chassis designs in the future. I'm hard at work bringing new ideas to life. The models are also available on GrabCAD, open to improvement and refinement: https://grabcad.com/library/flexcar-with-3d-printed-parts-1 If you have any suggestions or ideas, please don't hesitate to share them with me – I'd love to see what others come up with.
