Activity 6: Build the TaskBot
We need a robot. Because the focus of this guide is on working with PRIZM and the
Arduino Software (IDE), we do not need a complicated robot. With that in mind, we
created the PRIZM TaskBot. The TaskBot is meant to be simple, easy to build, and
exactly what we need for the purposes of this guide without any unnecessary parts.
That being said, everything you learn with this basic bot can be transferred to a
more complicated bot as you continue on your robotics journey.
The TaskBot uses two 12-volt motors mounted back to back for a good example of a
differential-drive robot. Two omni wheel assemblies on the opposite end combined
with the maneuverable drive make a perfect test vehicle for our work with PRIZM.
We will start with a basic drive frame and add more to it in later activities.
This build should be perfect for students who have little to no experience with
metal-based building systems.
Building Time Expectations
45-55 minutes
Real-World Connection
The construction of a machine will determine its effectiveness as well as its
durability. Engineers design machines (including robots) for specific purposes. For
instance, a bulldozer is built from very strong and durable materials to be able to
withstand the forces involved in pushing over trees and buildings or digging out
large holes in the ground.
STEM Extensions
Science
• Structure and function

• Materials
• Fasteners
Engineering
• Machine design
Math
• Measurement
• Modulus
Teacher note: Many factors
can affect building time,
including such things as set
organization and whether
the builder has a partner.
The above time is only an
estimate and is based on
an individual builder of
average experience who is
comfortable with hands-on
building activities and has
access to complete, well-
organized sets. Actual time
might vary.
