Scientific principles illustrated

The Photosensitive Robot kit offers valuable learning opportunities

Basic Electronics

Understand circuitry with a simple PCB and through-hole components. Learn about how components can be positioned neatly together on a PCB without the need for loads of wires to connect them. Learn about the function of some basic electronics components such as resistors, transistors and photoresistors.

Soldering Skills

Develop proficiency in soldering techniques for electronic components. These skills are pre-requisite for any aspiring electronics engineer. While through-hole component soldering is less common for today's advanced miniature electronics devices, it is still essential for those wishing to prototype their own electronics ideas or who wish to repair electronics devices.

Sensor Technology

Explore the functionality of photoresistors in responding to light. Learn how electronic sensors such as photoresistors can be used to provide input into a circuit to produce a desired output or action.

Robotics Basics

Gain insights into simple robotic movements and autonomic behaviors.

STEM Concepts

Learn fundamental concepts in Science, Technology, Engineering, and Mathematics.

DIY Experience

Enhance problem-solving skills and creativity through hands-on construction. Get that amazing feeling of accomplishment when you complete the project and see it come to life when you power it up.

Gateway to Advanced Projects

This project helps you to acquire skills and knowledge providing a foundation for more complex robotics and electronics projects.


This kit is a stepping stone for enthusiasts to delve into the exciting world of electronics and robotics.

Poor quality

Most if my parts came smashed. The IC leads were bent. Other electronic were bent ir broken..like they just threw the parts in the bag.

Hello Vincent. Thanks for your purchase and sorry to hear you were not satisfied. If you had contacted us with your concerns, we'd have made it 100% right and completly to your satisfaction; we always do. And of course, we still will make it right if you wish - just email info@thesciencehut.com and we'll look after you there.

With respect to the components being bent, they all include long, thin wire stems which are very easily bent during shipping and handling, but this in no way affects their functionality. Indeed, the bent stems are snipped off and thrown away as part of the assembly. We pack the components into bags and ship them in bubble-wrapped padded mailing bags which are more than adequate for these types of products. If we were to pack in a protective box (which is completely unnecessary), the customer would end up with a higher cost for the product and most likely have to pay for shipping too. The way this product is packed means we can sell it for only $14.95 and include free shipping for that low price. We want to keep our prices as low as possible because we want to make our products easily accessible for anyone interested in learning about science. Avoiding inflating prices with unnecessary packing costs helps us to do that.

As mentioned earlier, feel free to reach out to our customer support email above if you wish, they are there to help you.

Super cool

Only took my 14 year old son about an hour to assemble this and it works great. If you're looking for a good starter electronics kit, I highly recommend this one. You can angle the two photoresistors in different ways to change the way the robot reacts to light. Great fun to play with.

Brilliant

Great soldering project, not too difficult to assemble. It's amazing what you can do with so few basic electronics components. This little robot almost seems intelligent the way it 'sees' and moves towards a light source. Loving these STEM Electronics kits!

Cool simple robot

Excellent, except that the cables are thin, which makes it very easy to break them. Everything else, 10/10. Arrived sooner than expected.
