Google Glass Gimbal Control

These Google Glass control was migrated from the prototype 3D printed frame to a large heavy lift quadcopter gimbal. Below is a demonstration of real-time wireless control of the pitch and roll axes of a heavy-payload carrying gimbal, controlled hands-free by Google Glass. This control is a applied to a project I worked on at Simera Technology Group, see: Anax Heavy Lift Quadcopter.

Unfortunately the yaw motor for the large gimbal is faulty, but a full three-axis demonstration video will be posted as soon as the gimbal motor is replaced.

To apply this project to your own gimbal system, you can see my instructable:

Anax Heavy Lift Quadcopter

Anax (Greek: ἄναξ; from earlier ϝάναξ, wánax) is an ancient Greek word for “King”

The Anax Quadcopter with Gimbal Payload

The Anax quadcopter is rightfully named the Anax, it is part of a side project undertaken by Simera Technology Group. I was hired as an intern to take on the project and responsibilities of building, setting up and flying the quadcopter.

The purpose of the Anax is to serve as a testing platform capable of lifting heavy payloads, such as multi-spectral cameras developed by Simera to do data acquisition and testing. The first successful flight of the Anax took place on the 28th of Nov, 2014.

The Anax is capable of lifting a large gimbal with a heavy camera payload, and has undergone rigorous testing in the hopes that my undergraduate thesis, Gimbal Control by Means of Google Glass, can be applied to it.

The Mechabrewers

The Mechabrewers are the winners of the 2015 Pneudrive national South African engineering design competition. The winning design submission received an all-expenses-paid trip to the SEW and SMC head quarters in Germany and the UK.

More about us:

The Mechabrewers is a mechatronics design team from the University of Stellenbosch that was formed to compete in the Pneudrive Challenge, a national engineering design competition in South Africa. We love designing mechatronic systems through our specific and individual skill sets. Using our combined experience and expertise, we can solve any automation problem.

We undertook the project in collaboration with Stellenbrau Breweries to assist them in their production line by design a system that could potentially automate a specific process.

Our design submission for the 2015 Pneudrive competition was the BottleBot, an automated robotic arm intended to move beverage bottles around in a production line.

To assist with our design submission we also built a prototype of the BottleBot that was made out of wood and pneumatics. Below is a video of the prototype in action:

My FPV Quadcopters

Over the years I’ve built several FPV racing quadcopters. My current fleet looks something like this:

2016-09-15-115920_511x598_scrot

My first setup included ever:

  • DYS 1806 motors
  • AfroESC 12A ESC’s with SimonK firmware
  • Naze 32 Flight Controller
  • Turnigy Nano-Tech 45C 1300mAh batteries
  • Hobbyking FPV Camera starter kit

The second quad I built was a a variation with the diatone frame, in an attempt to build a warp-quad (a very, very fast quadcopter) with my newly acquired 2206 Tiger Motors, as shown below:

The third multirotor I built was a tricopter. I had access to a friend’s 3D printer and from that point on it felt like the world was my oyster. I was curious to see what the flight characteristics of a tricopter would feel like, so I nonchalantly printed one, and many hours later it was up in the air:

You can find the design on Thingiverse: http://www.thingiverse.com/make:143530

After realising that my motors were a little bit too powerful for the tricopter setup, I opted for a V-Tail, a quadcopter design that has enhanced yaw-control. Despite the awesome look, there aren’t many tutorials or details on tuning setups for this design, so getting it to fly properly was quite a challenge.

You can find the design on Thingiverse: http://www.thingiverse.com/thing:596820

My newest quadcopter is the EchoQuad 270, the frame is designed locally by a legend called Saadiq. FlyingRobot and EchoQuad have done an exceptional job of furthering the FPV racing scene in South Africa, and I commend them for that.

The setup on the EchoQuad quadcopter is as follows:

  • Tiger Motor 2206 2000kv Motors
  • ZTW Spider 18A Lite Opto ESCs
  • 1.2 Ghz VTx
  • Naze 32 Flight Controller
  • Turnigy Nano-Tech 45C 1300mAh batteries
  • Hobbyking FPV Camera starter kit

I recently got sponsored by Drone X Labs in Australia. They sent me enough parts to build two fully functional racing quads with their DXL Hyper X Frame:

Military Simulation Paintball

I recently discovered the military simulation paintball scene in Cape Town and was surprised to see how big it is. MilSim paintball is a form of paintball where the tactics, realism and scenarios each play very important roles. Strict rules apply and teams usually play against each other in good faith, trusting that each member will adhere to the set rules.

I recently played with an awesome team called Ghost Squad Paintball at one of the country’s best paintball ranges, called X Paintball. Check out the team on their website: http://www.ghostsquadpaintball.com/

The team meets up once a month to play at X-Paintball, if you’re interested contact the field in Somerset West to inquire about their open days.

Most MilSim games are play with magazine fed paintball guns, which enhance the style and feel of each game. The marker (or gun) I use at the moment is a Spyder EMR5.
