Build a Biomechanical Jumping Robot with Arduino Mega — Advanced Fitness Step Counter Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Engineer a multi-joint robotic leg that replicates a human crouch-spring-jump cycle — an advanced project for engineering students and makers. Four high-torque MG996R servos drive the joints, while the MPU6050 IMU provides real-time orientation data to trigger the jump sequence exactly when the squat phase is detected. Use this kit to demonstrate mechatronics principles, from PID control to servo synchronization, or prototype a next‑gen wearable fitness motion tracker.

What You'll Build

You'll assemble a four‑joint robotic leg on aluminium brackets, wire the servo driver and buck converter, and program an Arduino Mega to detect IMU tilt patterns. The firmware counts simulated “steps” and initiates a crouch‑spring‑jump sequence when the leg stabilizes. The complete robot executes a repeatable jump, verifying your hardware integration and closed‑loop control design. The same architecture can be adapted for bipedal walking or running gait studies.

What You'll Learn

• Servo trajectory planning and multi‑channel synchronization using the PCA9685 PWM driver
• IMU sensor fusion and angle-based step detection with the MPU6050
• Power system design under peak torque loads — LiPo battery, buck converter and bulk capacitance
• Hand‑soldering and mechanical assembly of a prototype motion platform

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit targets B.Tech ECE and EEE students tackling biomechatronics or robotics major projects, Smart India Hackathon teams prototyping motion-sensing solutions, and ATL Tinkering Lab mentors guiding advanced mechanics. It’s equally valuable for IIT, NIT, VIT, or BITS Pilani undergraduates exploring embedded control, sensor fusion, and high‑torque actuation.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
