HotRod + PocketLab Voyager

The PocketLab HotRod is a fun and creative take on the classic “physics cart”, except it’s not boring and it doesn’t look like a brick on wheels.
Kit includes a 3D printed cart, parts for bearings, axels, and wheels, bumpers, and a holder for a PocketLab Voyager.
All 3D printer files are on-line, so you can print your own extra cars and accessories.


The PocketLab HotRod and PocketLab Voyager

The PocketLab HotRod is a fun and creative take on the classic "physics cart", except it's not boring and it doesn't look like a brick on wheels. 

The HotRod zooms through classic investigations on force and motion, measuring position, velocity, acceleration, rotation, force, magnetism, and more. The brains of the HotRod is a PocketLab Voyager, which means its more than just a smart car - it's a genius car! In addition to traditional physics cart activities, you can also detach the PocketLab Voyager and conduct literally hundreds of other science experiments.

What's Included?

  • PocketLab Voyager Sensor
  • Micro USB charging cable
  • Hardshell case for PocketLab Voyager
  • Getting started cards
  • 3D printed HotRod cart
  • bearing, axel and wheel set
  • 100+ Lessons and Activities available on-line

PocketLab HotRod Features

The kit includes a detachable, fully functional PocketLab Voyager, an award winning wireless sensor that is capable of hundreds of science experiments. Measure the speed of your PocketLab HotRod, then detach the Voyager, strap it to a rocket and measure its altitude during launch. The possibilities are endless.

The detachable PocketLab Voyager can measure, acceleration, rotation, position, velocity, magnetism, barometric pressure, altitude, temperature, humidity, dew point, and heat index. Voyager connects via Bluetooth to the PocketLab app to stream and record data in real-time, and has onboard memory for recording data without a Bluetooth connection.

The PocketLab HotRod is designed to be customized. With a 3D printer you can design and print your own accesories or use one of our free designs from our library.

Super low friction bearings and low rolling resistance wheels make for excellent low friction “physics cart” experiments. You can 3D print as many PocketLab HotRods as you want for free.

Measure position, velocity, and acceleration using PocketLab Voyager’s built-in rangefinder or by attaching PocketLab Voyager to the PocketLab HotRod’s wheel. The built in accelerometer is also a great way to independently measure acceleration, especially during “impact” experiments. More options means more use cases.

PocketLab Voyager Sensor Functions

All the sensor functions are integrated into a small, rugged, and portable sensor device that can be attached to almost anything and used in almost any application. You can stream data from up to three measurements simultaneously to the PocketLab app and visualize the data in real-time.

Experienced STEM educators, scientists, and educational researchers have developed the library of PocketLab activities that emphasizes the Next Generation Science Standards (NGSS) from 4th grade through high school. University professors and researchers have also developed AP-level and university-level experiments that dive deep into physics and engineering concepts. You can find all of the lessons on the PocketLab Educator pages.
