3D printed “GorillaBot” robot run and jumps around 🦍 !

GorillaBot by Sebastian Coddington is a full 3D printed opensource robot based on the Baby MIT Cheetah!

Design Upgrades

The design is based on a five  bar linkage mechanism for each leg 2 servos power each leg for a total of 8 servos. The robot uses Arduino Nano as brain, a servo controller , x2 18560 Lipo battery and ultrasonic sensors to navigate in the track.

The robot was build to compete in the Toulouse Robot Race #TRR2021 (France)  where quadruped and biped robots compete in a 10 meter sprint race.

The race consists of a 10 meter autonomous sprint for biped and quadruped robots. The current record I gather for quadrupeds is 42 seconds for a 10 meter sprint.

Fully 3D printed & OpenSource

Everything apart from the electronics and screws to attach the electronics are 3D printable making GorillaBot fully customizable and easy to assemble, it can cost as low as 75$.

The list of electronic components is the following: 

  • 8x Tower Pro MG90S analog 180 deg servo
  • Sunfounder Wireless Servo Control Board
  • Arduino NANO
  • NRF24L01 Transceiver Module ( to use with remote controller )
  • Magnetometer (digital compass) QMC5883L GY-273
  • 1x Ultrasonic sensor HC-SR04
  • 2x 18650 3.7V Li-ion batteries
  • 18650 dual Battery holder with on off switch
  • 18650 Li-ion Battery charger
  • 4x female to female dupont jumper cables 10 cm long
  • 4x female to female dupont jumper cables 20 cm long
  • 10x Screws 2mm x 8mm
  • 3D printed parts 
  • Source Code ( Arduino )
