Romi Chassis and Accessories, Jrk G2 Motor Controllers, A-Star Programmable Controllers, Lidar Range finders, and Pololu Plastic Gearmotors

The Romi chassis is a differential-drive mobile robot platform with a diameter of 6.5″ (165 mm). The plastic components making up the chassis are available in six colors, either individually or in kits including motors and battery contacts. Control electronics and quadrature encoders are also available.

The Jrk G2 motor controllers are highly configurable brushed DC motor controllers that can be used as an open-loop speed control or for closed-loop speed or position control. They support a variety of interface modes, including USB, TTL serial, I²C, analog voltage, and hobby radio control (RC).

The Pololu A-Star microcontroller boards are general-purpose programmable modules based on Atmel AVR microcontrollers. A USB interface and preloaded Arduino-compatible bootloader on each A* makes it easy to get started programming them.

These compact lidar systems measure the time of flight (ToF) of infrared light pulses to quickly and accurately determine the absolute distance to targets up to several meters away.

A variety of low-current brushed DC motors with plastic gearboxes that offer power and speed comparable to a continuous-rotation RC servo at a fraction of the price.
