Step one
I was watching my favourite TV show BattleBots that’s when I got the idea to build my own BattleBots with my Lego Minestorms set
Step two
To make things simple to start off with I thought I would make it three wheeled and I would use the inside of a tire Lego brick so it would have not very much friction so it could pivot around easily
I also wanted a big hammer that could swing up and down
Step three
First, I found a base piece to put the hub on and then I attach the motors into the sockets on the hub Now I could start to make the hammer I wanted the hammer to have two spiky points at the front of it I quickly put this together and first it was very floppy and wouldn’t stay upright so I added some support underneath it I then put a long beam to attach it to the motor I had to put two connectors so it would stay upright the final part of the build was to attach the wheels but this was pretty easy. I plugged in the motors to the hub and attached two axles with two wheels on
Step four
Now it was time to program it I hadn’t really thought about this part yet first I had to figure out which will was which letter motor then? I decided that I wanted to make this remote control on the app I had never tried this before, but I had wanted to give it a go. to start off, I found the block that allowed me to use the remote control. I then did basic movements of forwards and backwards this worked fine. but when I tried left and right it did not move because it kept on getting stuck on the floor. this is when I realise that the friction was too high on the Tyres.
And then I replaced them for the inside which was plastic which glided along the floor quite easily now Now I had all of the movements I needed to make the hammer swing I wanted to make it so one press and release of a button would swing it forwards then backward then I realise this was quite hard as sometimes the hammer would swing too far back and then wouldn’t get down to the ground which Which meant I had to debug the code what I had done wrong was set it so it went backwards sometimes as I had accidentally not deleted my old code when I fully debugged that part it was fully working
Here are some photos and videos of it
