clev3r

This page covers clev3r (EV3 BASIC) only: how to set it up for the Ranger 8-Way (TOF8) on MINDSTORMS EV3, how to read every value, the commands it supports and examples. Use the switcher above to change product, host or software.

Setup

What you need

  • Sensor: Ranger 8-Way (TOF8) (EV3 edition, RJ12 plug).
  • Brick: LEGO MINDSTORMS EV3.
  • Software: clev3r (a BASIC programming environment for the EV3, also called EV3 Basic). The version tested for this site is v1.7.1.0. Pick this if you already use clev3r.

Install the software

  1. Install clev3r (v1.7.1.0 recommended).
  2. To open an example: open the .bp file in clev3r → "Compile and download" → run it from the folder starting with MBC_ in the EV3 file browser.

Make the software see the sensor

No extension needed. On the EV3 the sensor emulates an original LEGO sensor (most products are an "Infrared Sensor"), with exactly the same modes as the official EV3 software: Proximity / Beacon / Remote, with the same ranges.

  • Read them with BASIC commands such as IR_PROXIMITY / IR_BEACON / IR_REMOTE. See the readings below.
  • clev3r can also read modes that EV3-G and Classroom cannot, so examples marked "Pybricks / EV3 MicroPython / clev3r only" run here too.
  • Some products come with MBC subroutines. They are already inside the example files.

Important

Do not switch modes in the middle of a program. Every time the EV3 switches a sensor mode it stalls (about 1 s). Pick one mode at the start and use it for the whole run.

Wiring

  1. Plug the sensor into EV3 port 1 with the cable (any of 1~4 works; use the same port in the program).
  2. Turn the EV3 on first, then plug in the sensor.
  3. Latch up, push the plug in gently.

Wait 2~4 seconds after power-on

The Ranger 8-Way needs no calibration; plug it in and go. After power-on, wait 2~4 seconds for the 8 lasers to get ready; meanwhile everything reads 120 (cm). Start your program with a short wait before reading distances.

Channel 1 2 3 4 5 6 7 8
Facing left left-front 60° left-front 30° front front right-front 30° right-front 60° right

The table assumes the sensor faces forward with the components up. Put your hand on the robot's left: example 1 should show a negative direction. If it shows a positive one, the sensor is mounted the other way, and "turn left" / "turn right" in the examples must be swapped too.

First test

  1. Open the .bp of example 1 on this page and press "Compile and download".
  2. Run it from the folder starting with MBC_ in the EV3 file browser.
  3. If the number on the EV3 screen changes with what is in front of the sensor, everything is connected.

FAQ

  • Cannot find the program on the EV3? Look in the EV3 file browser for the folder starting with MBC_.
  • The number never changes? Unplug the sensor and plug it back in (the EV3 must be on first).
  • The program hiccups now and then? It switches sensor modes. Use one mode only.

Reading values

Code assumes port 1: Sensor.SetMode picks the mode, Sensor.ReadRawValue reads the n-th value.

What you need:

  • TOF8 eight-direction laser (EV3 edition)
  • EV3 brick

How to connect: TOF8 eight-direction laser in port 1.

    • Row 1 shows the straight-ahead distance (0~100)
    • Row 2 converts to centimetres: × 1.2
    • Wait 0.1 s

What you should see: Move your hand in front and the number follows; with nothing ahead it reads 100.

FAQ:

  • The number does not match a ruler? On EV3, 1 unit = 1.2 cm (for example 25 = 30 cm); 100 means nothing within 120 cm ahead.
  • The number stays at 0 or never changes? Turn the EV3 on before plugging in the sensor, or unplug and plug it back in; make sure there is no protective film over the laser.

Example 2: Stop 30 cm before the wall

What this example does: The robot drives forward and stops when something is within 30 cm (value 25) straight ahead.

What you need:

  • EV3 brick + Education base robot (left wheel on B, right wheel on C)
  • TOF8 eight-direction laser (EV3 edition)
  • A few boxes as obstacles

How to connect: TOF8 eight-direction laser in port 1, mounted at the front with lasers 4 and 5 facing straight ahead, about 5 cm above the ground.

    • Row 8 shows the distance of laser 8
    • Wait 0.1 s

What you should see: 8 rows of numbers, one per laser; bring your hand near a laser and that row gets smaller.

FAQ:

  • The number does not match a ruler? On EV3, 1 unit = 1.2 cm (for example 25 = 30 cm); 100 means nothing within 120 cm ahead.
  • Is laser 1 on the left or the right? Try it with your hand and write it down; you will need it when programming.

Example 4: Sumo chaser: turn towards the nearest object and charge

What this example does: Mode 2 tells you directly "where the nearest object is and how far", so you do not have to compare 8 numbers yourself. The robot turns towards the nearest object and charges; when it sees nothing it spins to search.

What you need:

  • EV3 brick + Education base robot (left wheel on B, right wheel on C)
  • TOF8 eight-direction laser (EV3 edition)
  • A can as the opponent

              • Object straight ahead: charge at full power
      • Otherwise:
        • Nothing nearby: spin on the spot to look for the opponent

What you should see: Put the can anywhere around the robot: it turns towards the can and pushes it.

FAQ:

  • The direction reads 8 or -8? ±8 means nothing within 120 cm in that direction, not "far left" or "far right".
  • It overshoots and swings back and forth? Lower the turning power 20, or change -1 and 1 to -2 and 2.

Example 5: Drive towards the most open direction

What this example does: Mode 2 also tells you "the most open direction". With proportional control the robot keeps heading for open space and finds its way out of a box maze.

What you need:

  • A few boxes as obstacles

  • It keeps driving into walls? The sign of the direction may be opposite to your robot: swap "+turn" and "−turn" in the program.

Example 6: Where is the nearest object, and how many millimetres away

Pybricks v4 / EV3 MicroPython v2.0 / clev3r only (the EV3-G and Classroom blocks cannot read this mode)

What this example does: Mode 5 gives two numbers at once: how many millimetres away the nearest object is, and in which direction (-7~+7). That is 12 times finer than the 1.2 cm units of mode 2. This example shows both numbers and beeps when something comes within 15 cm.

What you should see: Move your hand around the sensor: row 1 follows in millimetres and row 2 tells you whether your hand is on the left (negative) or right (positive); within 15 cm the EV3 keeps beeping.

FAQ:

  • The direction reads 8 or -8? ±8 means nothing within 120 cm in that direction, not "far left" or "far right".
  • The number stays at 0 or never changes? This mode needs sensor firmware v4.0 (2026-10) or later; update older firmware first.
  • Why is there no EV3-G / Classroom version? This example uses a new mode (firmware v4, 2026-10). The EV3-G and Classroom infrared blocks cannot read it; only Pybricks, EV3 MicroPython and clev3r can.

More questions

  • The EV3 shows an infrared sensor? Expected: the sensor emulates a LEGO sensor so the stock blocks can read it.
  • A short freeze when switching modes? The EV3 needs about 1 s per mode change. Stick to one mode during a run.

Still stuck? Contact us with your software and a screenshot of the program.
