Lego Technic Robots

Blip


 

This page will go into detail on my model of Blip.

Electronics

Blip uses the same electronics as Gabriel did, but with an extra Power Functions M motor powering the lifter.

Build

I built Blip starting with a 5 stud high base with the majority of the electronics in it, then built up the angled frame around the lifter assembly. Because the wheelbase is quite square, it can sometimes have difficulty turning on grippy surfaces, which can be seen in the drive test video. Please leave comments if you have suggestions on how I could make it a proper flipper!


Uppercut


 




This page outlines more details about my WIP of Uppercut.


Electronics

Uppercut's weapon is powered by two Mindstorms EV3 medium motors, and will hopefully be driven by two Mindstorms large servo motors. The large asymmetrical blade is spun at a ratio of around 6.65:1, and has hit quite hard in the tests I've done so far.

Build

The weapon frame features the distinctive forks of Uppercut, and also the 'horns' that assist in self-righting. Once completed, the build will sadly not be on the same scale as the two others I have, but will definitely be quite intimidating when its weapon is at top speed! The weapon itself was made by starting with the straight section, then getting the curve on the shorter end, and finally I just looked for places Technic beams could be placed to strengthen the structure. It was quite difficult getting it balanced, however adding small pieces at the required end of the blade was the way to get it spinning well.


Endgame




In this page I will explain a bit more about my Endgame model.


Electronics


Endgame uses a Powered Up Technic hub, and once completed will be driven by two Powered Up L motors. The asymmetrical spinner is powered by an XL motor, and the self-righter uses a Large Angular motor. The XL motor drives the spinner at a gear ratio of 5:1, with the self-righter being the opposite at 1:5. The four wheel drive (once finished) will be at a ratio of 1:1.667 to increase pushing power.


Build

The frame of Endgame is very strong, so strong in fact that I had difficulty putting it together! The pieces are (possibly excessively) interlocked, so it is very hard to break. The asymmetrical spinner has a large tooth, perfect for catching and breaking other robots. It also features Endgame's classic yellow stripe on the back and sides. The front wedge spells out the second half of this robot's name, and is in grey because I needed to make an example of what the wedge would look like, but didn't have enough orange to do it in the correct colour.


Gabriel




Hello, this page is going to explain a bit more about my model of Gabriel made from technic Lego.

Electronics

Gabriel is powered using a Power Functions battery box and receiver, and is driven by 2 L motors directly connected to the wheels. It is controlled by a standard Lego Power Functions controller. Using the weapon is simple, just pull down on both controller levers and the axe will swing down. Pushing both levers up will reset the axe.

Build

I built the wheels for Gabriel using inside out track pieces wrapped around a cross of technic beams. Sadly this makes the wheels not perfectly circular, but it doesn't have any difficulty driving unless on smooth, hard surfaces.

We took a trip to York at the weekend to compete in our first official event as a full competitor. Upon arriving at the venue, we realised we would have had no chance of finding it if we didn't have Thomas Yau there to point us into the right building! We were among the first to arrive, so we had time to set up and grab some space before the rest of the competitors, and spectators, arrived. With a total of 31 antweights and 12 beetleweights, there was barely enough space for everyone to work on their robots. The competition format was a sort of group stage format so everyone got 4 guaranteed fights but could have more in the form of playoffs. Fight 1: vs Baby Dead Bod This was an absolutely terrifying first fight to have, Baby Dead Bod is an immensely powerful horizontal spinner so I was not happy to face it this early on. That was quick! A single hit on the weapon was all it took to flex the weapon into the pulley, sending it flying and completely shearing the motor shaft. This wa...

Exposure 2.0 completed!

Image
 All metal has arrived and parts printed, and we just about got in weight (more on that later)! The first important parts to do were: printing the chassis, weapon uprights and front armour. Then, after quite a steep learning curve, we assembled our 1806 conversion drive without much difficulty. We had our first go at casting polyurethane wheels, and they came out really well and feel really grippy. We then had to wait a little for our new metal parts to arrive, and I decided to re-print the wedge with more walls. However, we finally ran out of green TPU! This meant we had to use the black TPU that we had difficulty printing, but after a few setting changes it went perfectly. Once the metal had arrived, it was time for a test weigh in. This unfortunately weighed in as 1.595kg with the heaviest setup (4 forks). Even with just two forks, it was around 55g overweight. This led to us completely redoing the wiring, trying to cut out as much unnecessary wire as possible. I reprinted the w...

BBB x LHG Summer Showdown

Image
 Here is the full event video, I will write the timestamps for each fight. BBB x LHG Summer Showdown 2024- All Fights - Bristol Bot Builders Beetleweight Combat Robots The venue for this event was lovely, however the constant rain was a bit annoying, especially when it dripped off the marquees down the back of my neck! We arrived at the venue and went into the tech check with the heaviest setup we could run, and passed safety with no issues.  Fight 1: (06:46) My first fight was against Om Nom and Carbon Copy. I was happy with this match up as I would be the only spinner against a grabber (?) and a cluster bot. The fight began and I quickly engaged with one of the halves of Carbon Copy, using my full weight to push it into the wall and slice some material off the front wedge. I then reversed to give myself a bit of a run up and hit the cluster again, this time ripping the wedge off and slamming it into the ceiling. Whilst this was happening, Om Nom had somehow gotten stuck with...
