Classic TI-RSLK Parts and Accessories

Use this motor driver and power distribution board to get your Romi chassis running quickly. It offers all of the same features as the smaller Power Distribution board for Romi Chassis — battery contact slots, reverse voltage protection, several power switching options, and easy access to the various power busses — and adds a two-channel motor driver and powerful switching step-down regulator that can supply a continuous 2.5 A at 5 V or 3.3 V. Just add a microcontroller and sensors to complete your Romi robot.

This replacement gearmotor for the Romi/TI-RSLK MAX has an encoder already installed. The assembly is ready to plug into corresponding headers on our various Romi electronics modules, including the Romi 32U4 control board and the Romi Motor Driver and Power Distribution Board. Two of these are included with the Pololu Chassis Kit for TI-RSLK MAX.

This sensor module has 8 IR LED/phototransistor pairs mounted on a 0.375" pitch, making it a great detector for a line-following robot. Pairs of LEDs are arranged in series to halve current consumption, and a MOSFET allows the LEDs to be turned off for additional sensing or power-savings options. Each sensor provides a separate digital I/O-measurable output.

This single-pole, double-throw (SPDT) momentary switch can be used as a general-purpose micro switch or tactile bump sensor for your robot. The switch body dimension is 20.0 x 6.4 x 10.2 mm, and the 16.3mm lever arm is has a roller at the tip.

The GP2Y0A21 Sharp distance sensor is a great way to add obstacle avoidance or motion sensing to your robot or any other project. With a detection range of 4″ to 32″ (10 cm to 80 cm) and an analog voltage indicating the distance, this sensor is very easy to use.

This 12-inch (30-cm) cable has 26 AWG wires with a 3-pin female JST PH-style connector that works with Sharp analog distance sensors that have mating PH connectors. The other ends of the wire are terminated with male pins for 0.1" housing. The wire color scheme matches the Sharp distance sensor pinout: red for power, black for ground, and white for signal.

These lightweight aluminum brackets make it easy to mount and integrate the Sharp GP2Y0A02, GP2Y0A21, and GP2Y0A41 Distance Sensors into your project. The brackets are strong enough to hold their position, but they can also be bent by hand to different angles if the application calls for it. These brackets, which allow for many different sensor mounting options, are sold in pairs, and four M3 screws and nuts are included for securing sensors to the brackets.

This #2-56, pan-head screw is 1/2″ (0.5″) long. It is made from steel, is zinc-plated, and comes in packs of 25.

This #4-40, pan-head screw is 1/2″ (0.5″) long. It is made from steel, is zinc-plated, and comes in packs of 25.
