The versatile Romi chassis is a great starting point for your next mobile robot. This kit includes all the basic mechanical parts to get up and running, including two motors, two wheels, one ball caster, and battery contacts. The wheels...

This power distribution board is designed specifically for the Romi chassis as a convenient way to access the chassis’s battery power and pass that on the rest of the electronics that make up your robot. It has slots for soldering...

Add quadrature encoders to the mini plastic gearmotors on your Romi chassis with this kit that uses a magnetic disc and Hall effect sensors to provide 12 counts per revolution of the motor shaft. The sensors operate from 3.5 V to 18 V...

This smart servo from XYZrobot was designed for their Bolide Y-01 Advanced Humanoid Robot, making it well suited for applications that require a lot of strong and complex actuation, such as humanoid robots, hexapod robots, and robotic...

The FS90 analog servo from FEETECH is a great general-purpose micro servo at a great price. Servo horns and associated hardware are included. Key specs at 6 V: 0.10 sec/60°, 21 oz-in (1.5 kg-cm), 9.0 g. This is a great general-purpose...

These tiny brushed DC gearmotors are available in a wide range of gear ratios—from 5:1 up to 1000:1—and with five different motors: high-power 6 V and 12 V motors with long-life carbon brushes (HPCB), and high-power (HP), medium power...

The compact (0.5″ × 0.7″) D24V10F9 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 9 V while allowing for a maximum output current of 1 A . This regulator offers typical efficiencies...

This switching regulator uses the SEPIC topology to produce 9 V from input voltages between 2.5 V and 18 V. The wide input range coupled with its ability to convert both higher and lower input voltages makes it useful for applications...

This is a breakout board for Allegro’s A4988 microstepping bipolar stepper motor driver. It has two voltage regulators (5 V and 3.3 V), eliminating the need for separate logic and motor supplies. The driver features adjustable current...

This small digital distance sensor detects objects between 0.5 cm and 15 cm (0.2″ and 6″) away. With its quick response time, small size, low current draw, and short minimum sensing distance, this sensor is a good choice for non-contact,...

This small digital distance sensor detects objects between 0.5 cm and 5 cm (0.2″ and 2″) away. With its quick response time, small size, low current draw, and short minimum sensing distance, this sensor is a good choice for non-contact,...

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 9 V . The board measures only 0.7″ × 0.7″, but it allows a typical continuous output current of up to 2.5 A...
