Mini Space Rover

A solar-assisted STEM rover demonstrating basic circuits, motors and renewable-energy concepts.

₹349 Batteries not included

About 145 g of parts recovered from discarded electronics get a second life in every kit. (Estimate)

  • A recovered solar panel, for example from a solar garden light, demonstrates renewable-energy concepts.
  • Salvaged DC motors with recovered wheels and gears.
  • A switch and LED lights to explore simple circuits.
  • Recycled cardboard or wooden chassis on a recycled base plate.

Price excludes delivery. Ships from Ambattur, Tamil Nadu. India Post delivery (Normal or Express) is calculated at checkout from your PIN code.

Solar-assisted, not solar-only. The rover demonstrates renewable-energy concepts. Motor operation depends on sufficient light.

Batteries are not included with ReSpark kits. New AA cells may be required for operation. Salvaged battery cells are never included.

About this kit

A rover that runs on a second-life solar panel.

The Mini Space Rover is a solar-assisted STEM rover. Students build the chassis, mount the motors and wheels, wire the switch and LEDs, and connect a recovered solar panel.

The panel is sized like the ones found in solar garden lights, recovered from suitable discarded solar devices and tested before it goes into a kit. It shows how light can be converted into electrical energy. How well the motors run depends on how much light reaches the panel.

What’s in the kit

Recovered where suitable. New where it matters.

ReSpark combines suitable recovered components with selected new components to create affordable, safe and reliable STEM kits.

Recovered / reused

Recovered / Reused Components

Components that can safely be recovered from suitable discarded electronics after inspection and testing.

  • Solar panelRecovered from suitable discarded solar devices, such as solar garden lights
  • DC motorsSalvaged from broken RC toys and electronic toys
  • Wheels and gearsRecovered from broken RC toys and suitable discarded devices
  • SwitchRecovered from suitable e-waste
  • LED lightsFrom old devices
  • Connecting wiresRecovered from suitable e-waste
  • Chassis and base plateRecycled cardboard or wooden chassis on a recycled base plate
  • Battery holder / casingWhere appropriate, reused after appropriate quality checks. It holds new cells only.
New

New Components

Components intentionally purchased new because they are inexpensive, safety-critical, difficult to recover reliably, or unsuitable for reuse.

  • Breadboard / simple control circuitA simple control and switch circuit setup, so it isn’t tied to an old device’s board

Not included: batteries. New AA cells may be required for operation. Salvaged battery cells are never included.
