An Arduino Uno is an excellent option to drive your SMARS. The SMARS case was specifically designed for the Arduino UNO (or clone). Official Arduinos are more expensive than Raspberry Pi Zero WH's and are only 8 bit but there is a wide range of open source code available, and they have plenty of IO pins.
Arduino is an open-source hardware and sofware platform based on easy-to-use electronics and code.Learn More
A bluetooth module can be easily added to a SMARS robot, there is code available for Arduinos and Raspberry Pi's so that you can remotely control it. The HC-06 bluetooth modules are cheap and connect to a TX and RX pin on the Arduino/Raspberry Pi/Microbit, however these do not work with iOS/iPhones - for iOS compatibility choose the HC-08, HC-09 or HC-10.

SMARS uses small 6v 150RPM motors to drive the robot around. These cannot be powered by the Arduino or Raspberry Pi directly and so need a driver board. These motors have a tiny gearbox to provide sufficient power to move the robot around. They are 3v-6volt DC, and are described as Short Shaft Torque Gear Box Motor. 200RPM & 300RPM motors are also available, which are much faster but have less torque.Learn More Buy
PCA9685 Servo Driver
The Quad SMARS uses a PCA9685 servo driver board to power and control the 8x servos (legs and feet). Some version of this board come pre-assembled; the servo driver cover doesn't have a hole for the large capacitor, but you can safely de-solder this (or just cut the legs off). You may also need to bend the header pins to the upright position to fit in the servo driver cover.Learn More Buy
Raspberry Pi Zero WH
The Raspberry Pi Zero WH is an excellent choice for driving a SMARS, they are cheap, have loads of GPIOs and the 'W' model comes with built in Wifi connectivity. The Raspberry Pi Zeo 'WH' comes with pre-soldered headers to make connecting to power and driver boards even easier.Learn More Buy
