This chassis base plate is a round piece of 1/8" (3 mm) acrylic with a 5" (127 mm) diameter and cutouts for building a differential-drive robot chassis based on our micro metal gearmotors and 42×19mm wheels. The chassis has assorted general-purpose holes and slots that support many configurations of sensors and other robot components.
These white plastic wheels have rubber tires measuring 42 mm (1.65?) in diameter and press-fit onto the 3mm D output shafts on many of our motors, including our micro metal gearmotors and our plastic gearmotors with 3mm D-shafts. Teeth on the hub optionally allow a reflectance sensor to be used for encoder feedback. These wheels are sold in pairs.
This Peltier is a thermoelectric cooler with the ability to heat and cool objects in minutes by simply feeding its terminals.
When reversing the feed the effect will be the opposite, that is, one side of the Peltier pellet will cool and the other will heat up. This allows a wide application in projects with Arduino like CPU cooler, mini-refrigerators and water heaters.
These white plastic wheels press-fit onto the 3mm D shafts on many of our motors, including our micro metal gearmotors and our mini plastic gearmotors, to make a nice drive solution for small robots. The wheels have silicone tires and measure 60 mm (2.36?) in diameter. Two additional mounting holes for 4-40 screws make it possible to use the wheel with several of our universal mounting hubs.
This is the Multi-Chassis Tank Kit, an easy to assemble and use robot chassis platform. The Multi-Chassis kit provides you with everything you need to give your robot a rugged tank tread platform with plenty of room for expansion to add various sensors and controllers. All you need to do is supply is a basic motor driver and power and you’ll be ready to drive!
The Pololu 3pi robot is a complete, high-performance mobile platform featuring two micro metal gearmotors, five reflectance sensors, an 8×2 character LCD, a buzzer, and three user pushbuttons, all connected to a C-programmable ATmega328 microcontroller.
