The B-robot EVO goes OFF-ROAD

off road small

Aaaand the B-robot EVO off-road version is here.

 

It has been easy to modify the original B-robot EVO adding new Off-road wheels (regular 83 mm diameter RC buggy wheels, quite easy to get and inexpensive). If you already have a B-robot, just modified the parameters indicated below in its code or upload this slightly modified CODE version to the Arduino:  BROBOT OFFROAD 

NOTE: We have used these NUTs to fix the wheels (working nicely so far)

Look for RC wheels (buggy car). 83 mm diameter (or so)
Create your Off-road Brobot!: Look in internet for RC wheels (buggy car). 83 mm diameter (or so) to turn your Brobot into a off road beast

JJrobots´s Brain SHIELD. Created to simplify the set up and integration of all the different devices involved in the jjrobots projects.

This SHIELD has:

  • TWO stepper motor OUTPUTs 
  • TWO SERVO OUTPUTs 
  • I2C communications
  • Push button (customisable)
  • SENSOR port (SONAR, IR…)
  • ESP12-E (ESP8266) WIFI module (you can communicate to this SHIELD from any smartphone/tablet/PC using it)

Some OPEN robots you can create with this Brain Shield:

  • B-ROBOT EVO is a remotely controlled self-balancing arduino robot created with 3D printed parts. With only two wheels, B-ROBOT is able to maintain his balance all the time by using his internal sensors and driving the motors. You can control your Robot, making him moving or spinning,  by sending command through a Smartphone, Tablet or PC while he keeps the balance.

  • The iBoardbot is an internet controlled robot capable of writing+drawing (and wiping!) on a glass surface.2
  • Remotely controlled Torch/ Laser robot: Laser pointer is a remotely controlled Arduino robot created with 3D printed parts. With only two servos, this robot is able to point any object in the X and Y axis.

3

  • Sphere-O-Bot: The Sphere-O-bot is a friendly art robot that can draw on spherical or egg-shaped objects from the size of a ping pong ball to a large duck egg (4-9 cm).

The Sphere-O-Bot is a simple 2 axis drawing machine that can draw on most spherical surfaces. You can use it to decorate balls or eggs.

  • Many more to come!

New parameters (they have been modified to reduce its stability, the new wide wheels improve its stability so we need to make the robot more agile) :

// NORMAL MODE PARAMETERS (MAXIMUN SETTINGS)
#define MAX_THROTTLE 580
#define MAX_STEERING 150
#define MAX_TARGET_ANGLE 12

// PRO MODE = MORE AGGRESSIVE (MAXIMUN SETTINGS)
