Meet Pip

Pip is a tiny robot on a 7 by 7 grid. Drive, watch bump, light, and distance, then tap sensor, brain, motor, and battery. Drive Pip and Pip's Parts are ready now. Think and Act will show up here when they are ready. No kit, no account, no upload.

Step 1 · DriveLet's go

Drive Pip

Steer Pip around the room. Watch bump, light, and distance, then queue up to six steps and press Run. Eight short missions.

Step 2 · PiecesLet's go

What is each piece?

Tap sensor, brain, motor, and battery. See which part looks, chooses, moves, and gives Pip energy.

Step 3 · ThinkComing soon

Think

Longer plans for Pip. This lab is not ready yet.

Step 4 · ActComing soon

Act

Motors and doing the plan. This lab is not ready yet.

Coming soon

How to start robotics without a kit

Sense, think, and act on a tablet. Drive Pip and name the pieces. More labs later.

1Why a sandbox beats a definition

A search result can tell you what a bumper is. It cannot show a child the moment the bumper lights up because they drove into a wall, then the choice to turn. That loop is the real first lesson.

2Sense, think, act

Robots do not magically know the room. They sample a few sensors, pick a next step, then move. Drive Pip keeps that loop tiny on purpose so it is visible on an iPad from typical viewing distance.

3What is ready today

Drive Pip and Pip's Parts are playable. Think and Act stay coming soon so the hub stays honest. Empty URLs would 404; coming-soon cards do not.

4Tablet first

Buttons are large. The grid is square. Sensors sit under the floor so a child can see cause and effect without pinching a tiny joystick. A mouse still works on a laptop.

5Tips for parents

Sit beside them for the first mission. Ask what the bumper says before they press Forward. Let them fail and retry. There is no score that follows them, only a local checklist of solved missions.

6What this is not

This is not Scratch, ROS, Arduino, or a USB robot. There is no camera, no AI chat, and no maze editor. Those belong later, if ever, after the first hour feels easy.

How to use this tool

  1. Open Drive Pip to meet bump, light, and distance on a 7 by 7 grid.
  2. Steer with Forward, Turn left, and Turn right. Watch the three sensors change.
  3. Queue up to six steps, then press Run to see Pip follow your plan.
  4. Open Pip's Parts to name sensor, brain, motor, and battery. Tap a piece to see it work.
  5. Come back later for Think and Act. Those labs are not ready yet.

Frequently asked questions

What is Learn Robotics on Justools?▾

It is a free browser sandbox for a first robot hour. You meet Pip, a tiny grid robot, drive with three sensors (bump, light, and distance), then think a short list of steps and run them. Drive Pip is the steer lab. Pip's Parts lets you tap sensor, brain, motor, and battery and see each piece work. It is not a textbook article, and it is not Scratch, ROS, or a kit that plugs into USB. Think and Act will appear on this hub when they are ready. Nothing is uploaded. Puzzle progress stays in this browser.

Why practice on a grid instead of reading about sensors?▾

A paragraph about sensors is easy for a search engine to summarize. A sandbox is not. You need to see the bumper change when they face a wall, then decide to turn. That loop (sense, think, act) is the actual idea of a robot, and it only clicks when they drive. Parents get a calm tablet session without accounts or hardware. Teachers get a shared activity that works in a browser. That is why this family exists as a lab, not as another explainer page.

Which lab can I use today?▾

Drive Pip and Pip's Parts are playable. Drive Pip is steer, sensors, and a six-step list. Pip's Parts is naming sensor, brain, motor, and battery on the same robot. Think and Act are coming later. They show as coming soon so you are not sent to a missing page.

Does this work on an iPad?▾

Yes. The grid and buttons are built for tablet thumbs first, then phone and laptop. Tap Forward or queue steps, then Run. No app store install and no extra plug-in.

What does sense, think, act mean here?▾

Sense is the three readouts: bump if a wall is ahead, light if the floor is a lamp, dim, or dark, and distance as empty cells ahead (0 to 3). Think is a list of at most six steps. Act is moving or turning, either one tap at a time or by running the list.

Will there be more robotics labs?▾

Yes. Think will grow longer sequences. Act will focus on doing. They are not pretend-live. When a lab is ready it will get its own URL under /learn/robotics.

Where is puzzle progress saved?▾

Solved Drive Pip and Pip's Parts missions are stored locally in this browser under Justools keys. There is no account and nothing is sent to a server. Clearing site data on the device will reset the checklists.

Who is this for?▾

Beginners who want a calm first hour with Pip. You do not need a classroom kit or prior coding. If you already build robots in Scratch or on hardware, this lab is still useful as a tiny sensor demo you can finish in a few minutes.
