Building a Greenhouse Robot (Part 1): Adventure

Wed, 04 Feb 2026 00:00:00 +0000

I’m doing this Zealab project now and it’s honestly been a rollercoaster already! The mission? Build an device installed on greenhose inspection robots that can detect and classify overgrown plants automatically. Sounds straightforward right? HA. Famous last words.

The concept is actually simpler than my last robot car project. Just a multi-BUS structure with sensors figuring out how far stuff is, then driving motors to move away. In theory, piece of cake. In practice… well, let me tell you about my little adventure yesterday.

Building a Greenhouse Robot (Part 2): Rain, Fog, and Victory

Okay so installation day was… not what I expected. At all.

The plan was simple: bring the device to the greenhouse, install it, power it up, watch it do its thing. The reality involved a humidity problem we hadn’t anticipated.

The greenhouse was warm, lush, and visibly moist. Plants sweating in the morning light, condensation beading on every surface. We set up the equipment, connected everything, and… the connection kept dropping. Not dramatically, just enough to be frustrating. The robot would initialize, then lose comms. Reboot, connect briefly, then drop again.

Housecare Robot Prototype Details

So, I just finished this summer program at SITP. Spent my vacation building a robot car from the ground up. And, well, it seems I’ve emerged with a new obsession. 🤖

The project itself was a small car we had to program entirely from scratch. I walked in feeling distinctly average, fully expecting to be the clueless one holding everyone back. But the instructors were genuinely supportive. And the other students? Also genuinely supportive. It wasn’t that competitive, ’look-how-smart-I-am’ atmosphere you sometimes get. It was more of a collective troubleshooting session, punctuated by shared snacks and small victories.

Hey! Nice to meet you! 👋

I’m Pengpeng Li, and you can call me Mailin. I’m a high school student in Shanghai Foreign Language School Affiliated to SISU.

🔭 What I’m into:

Mars & Space – I’m absolutely fascinated by the Red Planet. One day I want to go there! (Or at least help build robots that do.)
Sci-Fi & Three-Body – Huge fan of The Three-Body Problem trilogy. Dark forest theory? Chain of Suspicion? Mind-blowing! 🌌
Physics & Robotics – From quantum mechanics to building robot cars, I love understanding how things work and making my own creations.
AR/VR – The future is mixed reality. I’m interested in immersive experiences that blend digital and physical worlds.
Boxing 🥊 – Because sitting in front of screens all day isn’t healthy! Boxing keeps me grounded, disciplined, and ready to fight for my dreams.
