Our robot 2024/25

We use the Spike Prime robot. Our robot's name is MilliCube, or Miku for short. The name comes from the fact that our square-shaped robot this year features a gearbox, the complexity of which at certain moments reminds us of a Rubik's Cube, and jellyfishes (Est: Millimallikad) are central to our innovation project theme. The brick orientation is 90 degrees compared to the direction of movement.

We have:

  • Spike Prime brick
  • Gearbox
  • 4 medium motors
  • Gyroscope
  • 2 SPIKE PRIME 57mmx14mm wheels
  • 2 (steel) ball wheels
  • 2 color sensors

Our complete robot design file (in English) 2024/25 (Last update: 16. March)

In this file you can read everything that is about our this year's robot, robot game and its process.

The Gearbox

  • It uses one motor for gear switching and another for winding the ports that are in gear.
  • For gear shifting, we use LEGO Technic Gear Switcher’s gear shift dowels and long cogwheel transmissions.
  • The gearbox is a composition of ideas from Karl Joonas and a YouTube creator William Frantz.
  • GOAL: To create 4 outputs from 2 motors.

 

3D model of our gearbox made in Stud.io.

Attachments

We have a total of 5 attachments, each designed in different colors.

The frames of the attachments have the same structure and can be quickly and easily attached by just placing them onto the robot. We also made 3D models of all our attachments in Stud.io.

Blue attachment: 

  • A crane that moves up and down by a motor, along with cogwheels. We use it to collect the scuba diver (M04). Gear number 1 must be active for it to function.
  • A wave-shaped beam, which helps with solving the coral buds (M01) and removing the shark (M02).
  • A beam on the right side of the attachment, designed to solve the coral reef (M03).
  • A collector system with a rake/cage mechanism for collecting a krill and corals.
  • The attachment has ball wheels at the front and back of the frame to make it heavier and more stable.

 

Black-and-White attachment:

  • A catapult with a rubber band system, which we use to remove the trident (M14). We use LEGO belts that are tightened and locked with a trigger mechanism, which activates when the robot drives into the shipwreck, releasing the stored energy in the belts and launching the trident out of the shipwreck, hopefully landing in the home area.
  • A small collector system with a rake/cage mechanism for collecting 1 krill (M12).
  • A joint system made of angles and beams, which we use to knock the shark off the robot. This system is inspired by the angler fish (M05) mission.

 

Yellow attachment:

  • A scoop, made of beams with teeth and cross axles, which we use to transport the scuba diver (M03) and lift up the water sample (M14). Gear number 1 must be active for this to function.
  • A hammer in the right front corner of the attachment, that rotates and which we use to send the submersible away (M10). Gear number 2 must be active for this to function.
  • A ramp made of beams, which we use to lift up the mast of a shipwreck (M06).
  • The attachment has ball wheels at the front and back of the frame to make it heavier and more stable.

 

Green attachment:

  • A sting-like combination of cross axles that rotates in a circular motion. Gear number 4 must be active for it to function. We use this for solving Sonar Discovery (M11).
  • Collector system with a rake/cage mechanism for collecting krills, corals, and a plankton sample.
  • Box made of beams where the Kraken (M09) drops.
  • The attachment has ball wheels at the front and back of the frame to make it heavier and more stable.

 

Red attachment:

  • A box with a drawer at the top of a tower made of beams, which we use to drop 5 krills (M12) into the whale.
  • In front of the attachment are guides, which cause the whale's mouth to open when driving into it.
  • A block with a ramp, for changing the shipping lane (M13).
  • The attachment has ball wheels at the front and back of the frame to make it heavier and more stable.

Our robot 2023/24

We use the Spike Prime brick, with which we built a cute and compact robot. Our robot's name is Gigant-Beetle. The robot consists of two large motors for the wheels and two small motors for the attachments. It has two color sensors, and in some missions, we also use a gyroscope. The robot has a strong black body so that each attachment creates a different color effect. We have five attachments, of which 4 (colored ones) have names inspired by different insects. The robot also has a trunk where we store weights, hide cables, etc. To charge our robot, the trunk opens easily. Our maximum points are 360p.

RUNS

0. run – The robot fits in the launch area and doesn't lose precision tokens on the field.

1. run – We lift the rolling camera obstacle, pull the shooting platform camera into our target circle.

2. run – We solve the 3D cinema.

3. run – We lift the three buttons on the soundboard to the correct height.

4. run – We change the scene of the performance to orange and drive to the other side of the table.

5. run – We solve the stage mission and turn on the hologram projectors. (M06;M07)

6. run – We push the rolling camera to moving.

7. run – We take the expert (Anna), four orange fans, and the fully supported innovation project model to the museum area.

8. run – We ram into the printer and drive towards the tower. We raise the light show to blue and leave three orange little figures in the circle around the tower.

Attachments

Our robot has 5 attachments + 1 stable starting point frame. Four of these are built based on colors – blue (picture 1), red (picture 2), yellow (picture 3) and green (picture 4). Each colored attachment represents an insect. Green represents a grasshopper, yellow represents a bee, red represents a ladybug, and blue represents a butterfly. The robot's base itself is a beetle. The fifth attachment (picture 5) is small and a bit different. The attachments are attached to the robot from the front by pulling them on using a universal locking system. Each attachment has cross-shaped pieces that easily connect to the motor of our robot.

Yellow attachment – The yellow attachment consists of two scoops and this uses both of the two motors. We use this attachment for runs 1, 2, and 4. This is the only one of the colored attachments that we use on the western side of the table.

Picture 1

Red attachment – The red attachment consists of a smooth wall/beam, a cogwheel system, and a small but tall lever. We use this attachment on the eastern side of the table, for run 5. With it, we solve missions M06 and M07.

Picture 2

Blue attachment – The blue attachment consists of a scoop for carrying objects and a shaft lever. We use this attachment on the eastern side of the table, during runs 6 and 7. First, we solve mission M09 (camera) with the shaft lever, and then we transport a pile of gadgets to the museum area and solve the blue flower mission. This attachment does not use any motors.

Picture 3

Green attachment – The green attachment consists of a scoop-lift and direction guides, but it uses only one motor. We use this attachment on the eastern side of the table during run 8, the final run. With it, we solve the printer mission and the tower mission (M11). First, we ram into the printer, then head towards the tower, where we transport three orange fans and with the lift, raise the light show to the blue setting. Our robot game ends with the green attachment under the tower.

Picture 4

Fifth attachment – The fifth attachment was built after the semifinals, inspired by the Öökullid team’s attachment. We use this attachment on the western side of the table during run 3. With it, we solve mission M10. It is the only attachment that, unlike the colored ones, does not attach to the robot using the locking system.

Strategy

We chose the order of the missions based on which attachments are used for which missions and their respective locations. We created a timeline, marking the order in which we would complete the missions and began programming accordingly. We started by creating the basic structures, then proceeded to enhance and develop them as needed. Additionally, we marked on the robot’s game table diagram which attachment is responsible for each mission.

Attachment locking system

To attach the accessories, we have created an original locking system. When the attachment is put onto the robot, two levers appear on the sides. By pushing these levers together, the hooks attached to the sides of the robot latch onto the accessories and are secured in place by a rubber system.
