Petoi Programmable Robot Dog & Cat Comparison
Petoi programmable robot pets come in various flavors: Bittle X robot dog, Bittle STEM Kit/Robotics Kit, Nybble robot cat, and Nybble Q robot cat.
Bittle Robot Dog Family vs Nybble Robot Cat Family
- They all have 8 limbs. Bittle has 9 movable joints(servos), Nybble has 11 movable joints(servos).
- Head movement
- Bittle's head has one servo, enabling the head to move left & right
- Nybble's head has two servos, enabling the head to move left & right and up & down.
- Tail movement
- Bittle doesn't have a servo on its tailbone, so it cannot wag its tail
- Nybble has a servo on its tailbone, so it can wag its tail
- Nybble's head comes with a pair of ultrasonic sensors, so it has a pair of eyes to sense things. Its head is fully sealed and cannot attach any more sensors
- Bittle's mouth can open and clip on a sensor from Petoi Sensor Pack.
- Skills
- Bittle can perform backflips and frontflips.
- Nybble cannot backflip, front flip because it's heavier than Bittle with 2 extra servos and has a real tail. The tail may be broken during the process.
- They come with gyroscopes, so they can self-right after being upside down.
