After fixing the wheel suspension the new motors where added. Every motor has a power of ~350W, they are very similar to the smaller ones, in fact the inside is the same. As clearly visible they feature a wider profile which should be profitable on grass.
Before we start, there's one more thing that needs fixing. As you can see on the picture, the front right suspension is broken. This is not surprising now that it is printed from PETG and has been in operation for half a year.
The new wheel suspensions will be milled from aluminium and should therefore be much more robust.
Beside the broken wheel suspension I can already plan ahead what exactly I need to do.
First of all the wheel to wheel distance should be at least 450mm, mine is only ~300mm. To fit this rule I want to exchange the Motors with new ones, which have a longer shaft and have a wider profile.
The Moving objects should have a bumper to protect your own feet as well as other racers.
As mentioned above my feet have to be protected, that will be solved with the bumper.
Each racer needs to have a fuse to limit the input current, so that the competition is fair to everyone.
In order to participate in the HackyRacer competition on the emfcamp site, a moving object/racing car is of course required. Since I have motorized a Bobbycar before, I already have one such racing car. That's why this project shows how to make it conform to the rules, but also a little bit how to build the bobby car.
