Meet eBumper4:  Explore With Confidence

See how eBumper4 makes it easier and safer to fly near things.

What It Does


Fly as usual when there are no obstacles nearby.


When eBumper4 senses an obstacle in its field of view, it activates to reduce the likelihood of a collision.


eBumper4 “bumps” the drone away from the obstacle and returns control to the operator.

Supported Aircraft

eBumper4 is available for the DJI Phantom 2, Phantom 2 Vision, Phantom 2 Vision+ and the 3DR Iris+.

Obstacle Avoidance

eBumper4 uses echolocation (like bats or dolphins do) to detect obstacles as you fly. When the sensors detect an obstacle, eBumper4 slows your drone down to make sure it stops before something unfortunate happens.

Precision Control

eBumper4 helps you navigate your environment a little easier, so you can fly in places you may not have dared to go before.

  • Auto-Takeoff:  Take off and hover to 6 feet off the ground with the literal flip of a switch. No more unfortunate encounters with your living room ceiling.
  • Self-Centering:  Automatically centers the drone when flying between two objects.
  • Indoor Mode:  Finely control the position and speed of your drone when you're in tight spaces. Of course, you'll still have collision protection if you get too close.
  • Outdoor Mode:  Fly at higher speeds with collision protection in less cluttered environments.


eBumper is designed as a retrofit kit that attaches to pre-existing interfaces on your drone, and installs in about 10-20 minutes.  Here are the main installation steps for the eBumper on the DJI Phantom.
